FIELD

[0002] The present invention relates to the production of sugar hydrolysates from cellulosic material. More precisely the invention relates to production of fermentable sugars from lignocellulosic material by enzymatic conversion. The fermentable sugars are useful e.g. in the production of bioethanol, or for other purposes. In particular the invention is directed to a method for treating cellulosic material with cellobiohydrolase, endoglucanase, beta-glucosidase, and optionally xylanase, and to enzyme preparations and the uses thereof. The invention is further directed to novel cellulolytic polypeptides, polynucleotides encoding them, and to vectors and host cells containing the polynucleotides. Still further the invention is directed to uses of the polypeptides and to a method of preparing them.

BACKGROUND

[0003] Sugar hydrolysates can be used for microbial production of a variety of fine chemicals or biopolymers, such as organic acids e.g. lactic acid, or ethanol or other alcohols e.g. n-butanol, 1,3-propanediol, or polyhydroxyalkanoates (PHAs). The sugar hydrolysates may also serve as raw material for other non-microbial processes, e.g., for enrichment, isolation and purification of high value sugars or various polymerization processes. One of the major uses of the sugar hydrolysates is in the production of biofuels. The production of bioethanol and/or other chemicals may take place in an integrated process in a biorefinery (Wyman 2001).

[0004] Limited resources of fossil fuels, and increasing amounts of CO.sub.2 released from them and causing the greenhouse phenomenon have raised a need for using biomass as a renewable and clean source of energy. One promising, alternative technology is the production of biofuels i.e. ethanol from cellulosic materials. In the transportation sector biofuels are for the time being the only option, which could reduce the CO.sub.2 emissions by an order of magnitude. The ethanol can be used in existing vehicles and distribution systems and thus it does not require expensive infrastructure investments. Sugars derived from lignocellulosic renewable raw materials can also be used as raw materials for a variety of chemical products that can replace oil-based chemicals.

[0005] Most of the carbohydrates in plants are in the form of lignocellulose, which essentially consists of cellulose, hemicellulose, pectin and lignin. In a lignocellulose-to-ethanol process the lignocellulosic material is first pretreated either chemically or physically to make the cellulose fraction more accessible to hydrolysis. The cellulose fraction is then hydrolysed to obtain sugars that can be fermented by yeast into ethanol. Lignin is obtained as a main co-product that may be used as a solid fuel.

[0006] Bioethanol production costs are high and the energy output is low, and there is continuous research for making the process more economical. Enzymatic hydrolysis is considered the most promising technology for converting cellulosic biomass into fermentable sugars. However, enzymatic hydrolysis is used only to a limited amount at industrial scale, and especially when using strongly lignified material such as wood or agricultural waste the technology is not satisfactory. The cost of the enzymatic step is one of the major economical factors of the process. Efforts have been made to improve the efficiency of the enzymatic hydrolysis of the cellulosic material (Badger 2002).

[0007] US 2002/019 2774 A1 describes a continuous process for converting solid lignocellulosic biomass into combustible fuel products. After pretreatment by wet oxidation or steam explosion the biomass is partially separated into cellulose, hemicellulose and lignin, and is then subjected to partial hydrolysis using one or more carbohydrase enzymes (EC 3.2). Celluclast.TM., a commercial product by Novo Nordisk A/S containing cellulase and xylanase activities is given as an example.

[0008] US 2004/000 5674 A1 describes novel enzyme mixtures that can be used directly on lignocellulose substrate, whereby toxic waste products formed during pretreatment processes may be avoided, and energy may be saved. The synergistic enzyme mixture contains a cellulase and an auxiliary enzyme such as cellulase, xylanase, ligninase, amylase, protease, lipidase or glucuronidase, or any combination thereof. Cellulase in considered to include endoglucanase (EG), beta-glucosidase (BG) and cellobiohydrolase (CBH). The examples illustrate the use of a mixture of Trichoderma xylanase and cellulase preparations.

[0009] Kurabi et al. (2005) have investigated enzymatic hydrolysis of steam-exploded and ethanol organosolv-pretreated Douglas-fir by novel and commercial fungal cellulases. They tested two commercial Trichoderma reesei cellulase preparations, and two novel preparations produced by mutant strains of Trichoderma sp. and Penicillium sp. The Trichoderma sp. preparation showed significantly better performance than the other preparations. The better performance was believed to be at least partly due to a significantly higher beta-glucosidase activity, which relieves product inhibition of cellobiohydrolase and endoglucanase.

[0010] US 2004/005 3373 A1 pertains a method of converting cellulose to glucose by treating a pretreated lignocellulosic substrate with an enzyme mixture comprising cellulase and a modified cellobiohydrolase I (CBHI). The CBHI has been modified by inactivating its cellulose binding domain (CBD). Advantages of CBHI modification are e.g. better recovery and higher hydrolysis rate with high substrate concentration. The cellulase is selected from the group consisting of EG, CBH and BG. The CBHI is preferably obtained from Trichoderma.

[0011] US 2005/016 4355 A1 describes a method for degrading lignocellulosic material with one or more cellulolytic enzymes in the presence of at least one surfactant. Additional enzymes such as hemicellulases, esterase, peroxidase, protease, laccase or mixture thereof may also be used. The presence of surfactant increases the degradation of lignocellulosic material compared to the absence of surfactant. The cellulolytic enzymes may be any enzyme involved in the degradation of lignocellulose including CBH, EG, and BG.

[0012] There is a huge number of publications disclosing various cellulases and hemicellulases.

[0013] Cellobiohydrolases (CBHs) are disclosed e.g. in WO 03/000 941, which relates to CBHI enzymes obtained from various fungi. No physiological properties of the enzymes are provided, nor any examples of their uses. Hong et al. (2003b) characterizes CBHI of Thermoascus aurantiacus produced in yeast. Applications of the enzyme are not described. Tuohy et al. (2002) describe three forms of cellobiohydrolases from Talaromyces emersonii.

[0014] Endoglucanases of the cel5 family (EGs fam 5) are described e.g. in WO 03/062 409, which relates to compositions comprising at least two thermostable enzymes for use in feed applications. Hong et al. (2003a) describe production of thermostable endo-.beta.-1,4-glucanase from T. aurantiacus in yeast. No applications are explained. WO 01/70998 relates to .beta.-glucanases from Talaromyces. They also describe .beta.-glucanases from Talaromyces emersonii. Food, feed, beverage, brewing, and detergent applications are discussed. Lignocellulose hydrolysis is not mentioned. WO 98/06 858 describes beta-1,4-endoglucanase from Aspergillus niger and discusses feed and food applications of the enzyme. WO 97/13853 describes methods for screening DNA fragments encoding enzymes in cDNA libraries. The cDNA library is of yeast or fungal origin, preferably from Aspergillus. The enzyme is preferably a cellulase. Van Petegem et al. (2002) describe the 3D-structure of an endoglucanase of the cel5 family from Thermoascus aurantiacus. Parry et al. (2002) describe the mode of action of an endoglucanase of the cel5 family from Thermoascus aurantiacus.

[0015] Endoglucanases of the cel7 family (EGs fam 7) are disclosed e.g. in U.S. Pat. No. 5,912,157, which pertains Myceliphthora endoglucanase and its homologues and applications thereof in detergent, textile, and pulp. U.S. Pat. No. 6,071,735 describes cellulases exhibiting high endoglucanase activity in alkaline conditions. Uses as detergent, in pulp and paper, and textile applications are discussed. Bioethanol is not mentioned. U.S. Pat. No. 5,763,254 discloses enzymes degrading cellulose/hemicellulose and having conserved amino acid residues in CBD.

[0016] Endoglucanases of the cel45 family (EGs fam 45) are described e.g. in U.S. Pat. No. 6,001,639, which relates to enzymes having endoglucanase activity and having two conserved amino acid sequences. Uses in textile, detergent, and pulp and paper applications are generally discussed and treating of lignocellulosic material is mentioned but no examples are given. WO 2004/053039 is directed to detergent applications of endoglucanases. U.S. Pat. No. 5,958,082 discloses the use of endoglucanase, especially from Thielavia terrestris in textile application. EP 0495258 relates to detergent compositions containing Humicola cellulase. U.S. Pat. No. 5,948,672 describes a cellulase preparation containing endoglucanase, especially from Humicola and its use in textile and pulp applications. Lignocellulose hydrolysis is not mentioned.

[0017] A small amount of beta-glucosidase (BG) enhances hydrolysis of biomass to glucose by hydrolyzing cellobiose produced by cellobiohydrolases. Cellobiose conversion to glucose is usually the major rate-limiting step. Beta-glucosidases are disclosed e.g. in US 2005/021 4920, which relates to BG from Aspergillus fumigatus. The enzyme has been produced in Aspergillus oryzae and Trichoderma reesei. Use of the enzyme in degradation of biomass or detergent applications is generally discussed but not exemplified. WO02/095 014 describes an Aspergillus oryzae enzyme having cellobiase activity. Use in the production of ethanol from biomass is generally discussed but not exemplified. WO2005/074656 discloses polypeptides having cellulolytic enhancing activity derived e.g. from T. aurantiacus; A. fumigatus; T. terrestris and T. aurantiacus. WO02/26979 discloses enzymatic processing of plant material. U.S. Pat. No. 6,022,725 describes cloning and amplification of the beta-glucosidase gene of Trichoderma reesei, and U.S. Pat. No. 6,103,464 describes a method for detecting DNA encoding a beta-glucosidase from a filamentous fungus. No application examples are given.

[0018] Xylanases are described e.g. in FR2786784, which relates to a heat-stable xylanase, useful e.g. in treating animal feed and in bread making. The enzyme is derived from a thermophilic fungus, particularly of the genus Thermoascus.

[0019] U.S. Pat. No. 6,197,564 describes enzymes having xylanase activity, and obtained from Aspergillus aculeatus. Their application in baking is exemplified. WO 02/24926 relates to Talaromyces xylanases. Feed and baking examples are given. WO01/42433 discloses thermostable xylanase from Talaromyces emersonii for use in food and feed applications.

[0020] The best-investigated and most widely applied cellulolytic enzymes of fungal origin have been derived from Trichoderma reesei (the anamorph of Hypocrea jecorina). Consequently also most of the commercially available fungal cellulases are derived from Trichoderma reesei. However, the majority of cellulases from less known fungi have not been applied in processes of practical importance such as in degrading cellulosic material, including lignocellulose.

[0021] There is a continuous need for new methods of degrading cellulosic substrates, in particular lignocellulosic substrates, and for new enzymes and enzyme mixtures, which enhance the efficiency of the degradation. There is also a need for processes and enzymes, which work at high temperatures, thus enabling the use of high biomass consistency and leading to high sugar and ethanol concentrations. This approach may lead to significant saving in energy and investments costs. The high temperature also decreases the risk of contamination during hydrolysis. The present invention aims to meet at least part of these needs.

DETAILED DESCRIPTION

[0060] Cellulose is the major structural component of higher plants. It provides plant cells with high tensile strength helping them to resist mechanical stress and osmotic pressure. Cellulose is a .beta.-1,4-glucan composed of linear chains of glucose residues joined by .beta.-1,4-glycosidic linkages. Cellobiose is the smallest repeating unit of cellulose. In cell walls cellulose is packed in variously oriented sheets, which are embedded in a matrix of hemicellulose and lignin. Hemicellulose is a heterogeneous group of carbohydrate polymers containing mainly different glucans, xylans and mannans. Hemicellulose consists of a linear backbone with .beta.-1,4-linked residues substituted with short side chains usually containing acetyl, glucuronyl, arabinosyl and galactosyl. Hemicellulose can be chemically cross-linked to lignin. Lignin is a complex cross-linked polymer of variously substituted p-hydroxyphenylpropane units that provides strength to the cell wall to withstand mechanical stress, and it also protects cellulose from enzymatic hydrolysis.

[0061] Lignocellulose is a combination of cellulose and hemicellulose and polymers of phenol propanol units and lignin. It is physically hard, dense, and inaccessible and the most abundant biochemical material in the biosphere. Lignocellulose containing materials are for example: hardwood and softwood chips, wood pulp, sawdust and forestry and wood industrial waste; agricultural biomass as cereal straws, sugar beet pulp, corn stover and cobs, sugar cane bagasse, stems, leaves, hulls, husks, and the like; waste products as municipal solid waste, newspaper and waste office paper, milling waste of e.g. grains; dedicated energy crops (e.g., willow, poplar, switchgrass or reed canarygrass, and the like). Preferred examples are corn stover, switchgrass, cereal straw, sugarcane bagasse and wood derived materials.

[0062] "Cellulosic material" as used herein, relates to any material comprising cellulose, hemicellulose and/or lignocellulose as a significant component. "Lignocellulosic material" means any material comprising lignocellulose. Such materials are e.g. plant materials such as wood including softwood and hardwood, herbaceous crops, agricultural residues, pulp and paper residues, waste paper, wastes of food and feed industry etc. Textile fibres such as cotton, fibres derived from cotton, linen, hemp, jute and man made cellulosic fibres as modal, viscose, lyocel are specific examples of cellulosic materials.

[0063] Cellulosic material is degraded in nature by a number of various organisms including bacteria and fungi. Cellulose is typically degraded by different cellulases acting sequentially or simultaneously. The biological conversion of cellulose to glucose generally requires three types of hydrolytic enzymes: (1) Endoglucanases which cut internal beta-1,4-glucosidic bonds; (2) Exocellobiohydrolases that cut the dissaccharide cellobiose from the end of the cellulose polymer chain; (3) Beta-1,4-glucosidases which hydrolyze the cellobiose and other short cello-oligosaccharides to glucose. In other words the three major groups of cellulases are cellobiohydrolases (CBH), endoglucanases (EG) and beta-glucosidases (BG).

[0064] Degradation of more complex cellulose containing substrates requires a broad range of various enzymes. For example lignocellulose is degraded by hemicellulases, like xylanases and mannanases. Hemicellulase is an enzyme hydrolysing hemicellulose.

[0065] "Cellulolytic enzymes" are enzymes having "cellulolytic activity," which means that they are capable of hydrolysing cellulosic substrates or derivatives thereof into smaller saccharides. Cellulolytic enzymes thus include both cellulases and hemicellulases. Cellulases as used herein include cellobiohydrolase, endoglucanase and beta-glucosidase.

[0066] T. reesei has a well known and effective cellulase system containing two CBHs, two major and several minor EGs and BGs. T. reesei CBHI (Cel7A) cuts sugar from the reducing end of the cellulose chain, has a C-terminal cellulose binding domain (CBD) and may constitute up to 60% of the total secreted protein. T. reesei CBHII (Cel6A) cuts sugar from the non-reducing end of the cellulose chain, has an N-terminal cellulose binding domain and may constitute up to 20% of the total secreted protein. Endoglucanases EGI (Cel7B), and EGV (Cel45A) have a CBD in their C-terminus, EGII (Cel5A) has an N-terminal CBD and EGIII (Cel12A) does not have a cellulose binding domain at all. CBHI, CBHII, EGI and EGII are so called "major cellulases" of Trichoderma comprising together 80-90% of total secreted proteins. It is known to a man skilled in the art that an enzyme may be active on several substrates and enzymatic activities can be measured using different substrates, methods and conditions. Identifying different cellulolytic activities is discussed for example in van Tilbeurgh et al. 1988.

[0067] In addition to a catalytic domain/core expressing cellulolytic activity cellulolytic enzymes may comprise one or more cellulose binding domains (CBDs), also named as carbohydrate binding domains/modules (CBD/CBM), which can be located either at the N- or C-terminus of the catalytic domain. CBDs have carbohydrate-binding activity and they mediate the binding of the cellulase to crystalline cellulose but have little or no effect on cellulase hydrolytic activity of the enzyme on soluble substrates. These two domains are typically connected via a flexible and highly glycosylated linker region.

[0068] "Cellobiohydrolase" or "CBH" as used herein refers to enzymes that cleave cellulose from the end of the glucose chain and produce mainly cellobiose. They are also called 1,4-beta-D-glucan cellobiohydrolases or cellulose 1,4-beta-cellobiosidases. They hydrolyze the 1,4-beta-D-glucosidic linkages from the reducing or non-reducing ends of a polymer containing said linkages, such as cellulose, whereby cellobiose is released. Two different CBHs have been isolated from Trichoderma reesei, CBHI and CBHII. They have a modular structure consisting of a catalytic domain linked to a cellulose-binding domain (CBD). There are also cellobiohydrolases in nature that lack CBD.

[0069] "Endoglucanase" or "EG" refers to enzymes that cut internal glycosidic bonds of the cellulose chain. They are classified as EC 3.2.1.4. They are 1,4-beta-D-glucan 4-glucanohydrolases and catalyze endohydrolysis of 1,4-beta-D-glycosidic linkages in polymers of glucose such as cellulose and derivatives thereof. Some naturally occurring endoglucanases have a cellulose binding domain, while others do not. Some endoglucanases have also xylanase activity (Bailey et al., 1993).

[0070] "Beta-glucosidase" or "BG" or ".beta.G" refers to enzymes that degrade small soluble oligosaccharides including cellobiose to glucose. They are classified as EC 3.2.1.21. They are beta-D-glucoside glucohydrolases, which typically catalyze the hydrolysis of terminal non-reducing beta-D-glucose residues. These enzymes recognize oligosaccharides of glucose. Typical substrates are cellobiose and cellotriose. Cellobiose is an inhibitor of cellobiohydrolases, wherefore the degradation of cellobiose is important to overcome end-product inhibition of cellobiohydrolases.

[0071] Xylanases are enzymes that are capable of recognizing and hydrolyzing hemicellulose. They include both exohydrolytic and endohydrolytic enzymes. Typically they have endo-1,4-beta-xylanase (EC 3.2.1.8) or beta-D-xylosidase (EC 3.2.1.37) activity that breaks down hemicellulose to xylose. "Xylanase" or "Xyn" in connection with the present invention refers especially to an enzyme classified as EC 3.2.1.8 hydrolyzing xylose polymers of lignocellulosic substrate or purified xylan.

[0072] In addition to this cellulases can be classified to various glycosyl hydrolase families according their primary sequence, supported by analysis of the three dimensional structure of some members of the family (Henrissat 1991, Henrissat and Bairoch 1993, 1996). Some glycosyl hydrolases are multifunctional enzymes that contain catalytic domains that belong to different glycosylhydrolase families. Family 3 consists of beta-glucosidases (EC 3.2.1.21) such as Ta BG_81, At BG_101 and Ct BG_76 described herein. Family 5 (formerly known as celA) consists mainly of endoglucanases (EC 3.2.1.4) such as Ta EG_28 described herein. Family 7 (formerly cellulase family celC) contains endoglucanases (EC 3.2.1.4) and cellobiohydrolases (EC 3.2.1.91) such as Ct EG_54, Ta CBH, At CBH_A, At CBH_C and Ct CBH described herein. Family 10 (formerly celF) consists mainly of xylanases (EC 3.2.1.8) such as Ta XYN_30 and At XYN_60 described herein. Family 45 (formerly celK) contains endoglucanases (EC 3.2.1.4) such as At EG_40 and At EG_40 like described herein.

[0073] Cellulolytic enzymes useful for hydrolyzing cellulosic material are obtainable from Thermoascus aurantiacus, Acremonium thermophilum, or Chaetomium thermophilum. "Obtainable from" means that they can be obtained from said species, but it does not exclude the possibility of obtaining them from other sources. In other words they may originate from any organism including plants. Preferably they originate from microorganisms e.g. bacteria or fungi. The bacteria may be for example from a genus selected from Bacillus, Azospirillum and Streptomyces. More preferably the enzyme originates from fungi (including filamentous fungi and yeasts), for example from a genus selected from the group consisting of Thermoascus, Acremonium, Chaetomium, Achaetomium, Thielavia, Aspergillus, Botrytis, Chrysosporium, Collybia, Fomes, Fusarium, Humicola, Hypocrea, Lentinus, Melanocarpus, Myceliophthora, Myriococcum, Neurospora, Penicillium, Phanerochaete, Phlebia, Pleurotus, Podospora, Polyporus, Rhizoctonia, Scytalidium, Pycnoporus, Trametes and Trichoderma.

[0074] According to a preferred embodiment of the invention the enzymes are obtainable from Thermoascus aurantiacus strain ALKO4242 deposited as CBS 116239, strain ALKO4245 deposited as CBS 116240 presently classified as Acremonium thermophilium, or Chaetomium thermophilum strain ALKO4265 deposited as CBS 730.95.

[0075] The cellobiohydrolase preferably comprises an amino acid sequence having at least 80% identity to SEQ ID NO: 2, 4, 6 or 8, or an enzymatically active fragment thereof.

[0076] These CBHs have an advantageous cellulose inhibition constant compared to that of Trichoderma reesei CBH, and they show improved hydrolysis results when testing various cellulosic substrates. SEQ ID NO: 2 and 4 do not comprise a CBD. Particularly enhanced hydrolysis results may be obtained when a cellulose binding domain (CBD) is attached to a CBH that has no CBD of its own. The CBD may be obtained e.g. from a Trichoderma or Chaetomium species, and it is preferably attached to the CBH via a linker. The resulting fusion protein containing a CBH core region attached to a CBD via a linker may comprise an amino acid sequence having at least 80% identity to SEQ ID NO: 28 or 30. Polynucleotides comprising a sequence of SEQ ID NO: 27 or 29 encode such fusion proteins.

[0077] The endoglucanase may comprise an amino acid sequence having at least 80% identity to SEQ ID NO: 10, 12, 14 or 16, or an enzymatically active fragment thereof. These endoglucanases have good thermostability.

[0078] The beta-glucosidase may comprise an amino acid sequence having at least 80% identity to SEQ ID NO: 22, 24 or 26, or an enzymatically active fragment thereof. These beta-glucosidases have good resistance to glucose inhibition, which is advantageous to avoid end product inhibition during enzymatic hydrolysis of cellulosic material. The beta-glucosidases may also be used in preparing sophorose, a cellulase inducer used in cultivation of T. reesei.

[0080] By the term "identity" is here meant the global identity between two amino acid sequences compared to each other from the first amino acid encoded by the corresponding gene to the last amino acid. The identity of the full-length sequences is measured by using Needleman-Wunsch global alignment program at EMBOSS (European Molecular Biology Open Software Suite; Rice et al., 2000) program package, version 3.0.0, with the following parameters: EMBLOSUM62, Gap penalty 10.0, Extend penalty 0.5. The algorithm is described in Needleman and Wunsch (1970). The man skilled in the art is aware of the fact that results using Needleman-Wunsch algorithm are comparable only when aligning corresponding domains of the sequence. Consequently comparison of e.g. cellulase sequences including CBD or signal sequences with sequences lacking those elements cannot be done.

[0081] According to one embodiment of the invention, a cellulolytic polypeptide is used that has at least 80, 85, 90, 95 or 99% identity to SEQ ID NO: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24 or 26 or at least to its enzymatically active fragment.

[0082] By the term "enzymatically active fragment" is meant any fragment of a defined sequence that has cellulolytic activity. In other words an enzymatically active fragment may be the mature protein part of the defined sequence, or it may be only an fragment of the mature protein part, provided that it still has cellobiohydrolase, endoglucanase, beta-glucosidase or xylanase activity.

[0083] The cellulolytic enzymes are preferably recombinant enzymes, which may be produced in a generally known manner. A polynucleotide fragment comprising the enzyme gene is isolated, the gene is inserted under a strong promoter in an expression vector, the vector is transferred into suitable host cells and the host cells are cultivated under conditions provoking production of the enzyme. Methods for protein production by recombinant technology in different host systems are well known in the art (Sambrook et al., 1989; Coen, 2001; Gellissen, 2005). Preferably the enzymes are produced as extracellular enzymes that are secreted into the culture medium, from which they can easily be recovered and isolated. The spent culture medium of the production host can be used as such, or the host cells may be removed therefrom, and/or it may be concentrated, filtrated or fractionated. It may also be dried.

[0084] Isolated polypeptide in the present context may simply mean that the cells and cell debris have been removed from the culture medium containing the polypeptide. Conveniently the polypeptides are isolated e.g. by adding anionic and/or cationic polymers to the spent culture medium to enhance precipitation of cells, cell debris and some enzymes that have unwanted side activities. The medium is then filtrated using an inorganic filtering agent and a filter to remove the precipitants formed. After this the filtrate is further processed using a semi-permeable membrane to remove excess of salts, sugars and metabolic products.

[0085] According to one embodiment of the invention, the heterologous polynucleotide comprises a gene similar to that included in a microorganism having accession number DSM 16723, DSM 16728, DSM 16729, DSM 16727, DSM 17326, DSM 17324, DSM 17323, DSM 17729, DSM 16724, DSM 16726, DSM 16725, DSM 17325 or DSM 17667.

[0086] The production host can be any organism capable of expressing the cellulolytic enzyme. Preferably the host is a microbial cell, more preferably a fungus. Most preferably the host is a filamentous fungus. Preferably the recombinant host is modified to express and secrete cellulolytic enzymes as its main activity or one of its main activities. This can be done by deleting major homologous secreted genes e.g. the four major cellulases of Trichoderma and by targeting heterologous genes to a locus that has been modified to ensure high expression and production levels. Preferred hosts for producing the cellulolytic enzymes are in particular strains from the genus Trichoderma or Aspergillus.

[0087] The enzymes needed for the hydrolysis of the cellulosic material according to the invention may be added in an enzymatically effective amount either simultaneously e.g. in the form of an enzyme mixture, or sequentially, or as a part of the simultaneous saccharification and fermentation (SSF). Any combination of the cellobiohydrolases comprising an amino acid sequence having at least 80% identity to SEQ ID NO: 2, 4, 6 or 8 or to an enzymatically active fragment thereof may be used together with any combination of endoglucanases and beta-glucosidases. If the cellulosic material comprises hemicellulose, hemicellulases, preferably xylanases are additionally used for the degradation. The endoglucanases, beta-glucosidases and xylanases may be selected from those described herein, but are not limited to them. They can for example also be commercially available enzyme preparations. In addition to cellulases and optional hemicellulases one or more other enzymes may be used, for example proteases, amylases, laccases, lipases, pectinases, esterases and/or peroxidases. Another enzyme treatment may be carried out before, during or after the cellulase treatment.

[0088] The term "enzyme preparation" denotes to a composition comprising at least one of the desired enzymes. The preparation may contain the enzymes in at least partially purified and isolated form. It may even essentially consist of the desired enzyme or enzymes. Alternatively the preparation may be a spent culture medium or filtrate containing one or more cellulolytic enzymes. In addition to the cellulolytic activity, the preparation may contain additives, such as mediators, stabilizers, buffers, preservatives, surfactants and/or culture medium components. Preferred additives are such, which are commonly used in enzyme preparations intended for a particular application. The enzyme preparation may be in the form of liquid, powder or granulate. Preferably the enzyme preparation is spent culture medium. "Spent culture medium" refers to the culture medium of the host comprising the produced enzymes. Preferably the host cells are separated from the said medium after the production.

[0089] According to one embodiment of the invention the enzyme preparation comprises a mixture of CBH, EG and BG, optionally together with xylanase and/or other enzymes. The CBH comprises an amino acid sequence having at least 80% identity to SEQ ID NO: 2,4,6 or 8 or to an enzymatically active fragment thereof, and it may be obtained from Thermoascus aurantiacus, Acremonium thermophilum, or Chaetomium thermophilum, whereas EG, BG and xylanase may be of any origin including from said organisms. Other enzymes that might be present in the preparation are e.g. proteases, amylases, laccases, lipases, pectinases, esterases and/or peroxidases.

[0090] Different enzyme mixtures and combinations may be used to suit different process conditions. For example if the degradation process is to be carried out at a high temperature, thermostable enzymes are chosen. A combination of a CBH of family 7 with an endoglucanase of family 45, optionally in combination with a BG of family 3 and/or a xylanase of family 10 had excellent hydrolysis performance both at 45.degree. C., and at elevated temperatures.

[0091] Cellulolytic enzymes of Trichoderma reesei are conventionally used at temperatures in the range of about 40-50.degree. C. in the hydrolysis, and at 30-40.degree. C. in SSF. CBH, EG, BG and Xyn obtainable from Thermoascus aurantiacus, Acremonium thermophilum, or Chaetomium thermophilum are efficient at these temperatures too, but in addition most of them also function extremely well at temperatures between 50.degree. C. and 75.degree. C., or even up to 80.degree. C. and 85.degree. C., such as between 55.degree. C. and 70.degree. C., e.g. between 60.degree. C. and 65.degree. C. For short incubation times enzyme mixtures are functional up to even 85.degree. C., for complete hydrolysis lower temperatures are normally used.

[0092] The method for treating cellulosic material with CBH, EG, BG and Xyn is especially suitable for producing fermentable sugars from lignocellulosic material. The fermentable sugars may then be fermented by yeast into ethanol, and used as fuel. They can also be used as intermediates or raw materials for the production of various chemicals or building blocks for the processes of chemical industry, e.g. in so called biorefinery. The lignocellulosic material may be pretreated before the enzymatic hydrolysis to disrupt the fiber structure of cellulosic substrates and make the cellulose fraction more accessible to the cellulolytic enzymes. Current pretreatments include mechanical, chemical or thermal processes and combinations thereof. The material may for example be pretreated by steam explosion or acid hydrolysis.

[0093] A number of novel cellulolytic polypeptides were found in Thermoascus aurantiacus, Acremonium thermophilum, and Chaetomium thermophilum. The novel polypeptides may comprise a fragment having cellulolytic activity and be selected from the group consisting of a polypeptide comprising an amino acid sequence having at least 66%, preferably 70% or 75%, identity to SEQ ID NO: 4, 79% identity to SEQ ID NO: 6, 78% identity to SEQ ID NO: 12, 68%, preferably 70% or 75%, identity to SEQ ID NO: 14, 72%, preferably 75%, identity to SEQ ID NO: 16, 68%, preferably 70% or 75%, identity to SEQ ID NO: 20, 74% identity to SEQ ID NO: 22 or 24, or 78% identity to SEQ ID NO: 26.

[0094] The novel polypeptides may also be variants of said polypeptides. A "variant" may be a polypeptide that occurs naturally e.g. as an allelic variant within the same strain, species or genus, or it may have been generated by mutagenesis. It may comprise amino acid substitutions, deletions or insertions, but it still functions in a substantially similar manner to the enzymes defined above i.e. it comprises a fragment having cellulolytic activity.

[0095] The cellulolytic polypeptides are usually produced in the cell as immature polypeptides comprising a signal sequence that is cleaved off during secretion of the protein. They may also be further processed during secretion both at the N-terminal and/or C-terminal end to give a mature, enzymatically active protein. A polypeptide "comprising a fragment having cellulolytic activity" thus means that the polypeptide may be either in immature or mature form, preferably it is in mature form, i.e. the processing has taken place.

[0096] The novel polypeptides may further be a "fragment of the polypeptides or variants" mentioned above. The fragment may be the mature form of the proteins mentioned above, or it may be only an enzymatically active part of the mature protein. According to one embodiment of the invention, the polypeptide has an amino acid sequence having at least 80, 85, 90, 95, or 99% identity to SEQ ID NO: 4, 6, 12, 14, 16, 20, 22, 24 or 26, or to a cellulolytically active fragment thereof. It may also be a variant thereof, or a fragment thereof having cellobiohydrolase, endoglucanase, xylanase, or beta-glucosidase activity. According to another embodiment of the invention, the polypeptide consists essentially of a cellulolytically active fragment of a sequence of SEQ ID NO: 4, 6, 12, 14, 16, 20, 22, 24 or 26.

[0097] The novel polynucleotides may comprise a nucleotide sequence of SEQ ID NO: 3, 5, 11, 13, 15, 19, 21, 23 or 25, or a sequence encoding a novel polypeptide as defined above, including complementary strands thereof. Polynucleotide as used herein refers to both RNA and DNA, and it may be single stranded or double stranded. The polynucleotide may also be a fragment of said polynucleotides comprising at least 20 nucleotides, e.g. at least 25, 30 or 40 nucleotides. According to one embodiment of the invention it is at least 100, 200 or 300 nucleotides in length. Further the polynucleotide may be degenerate as a result of the genetic code to any one of the sequences as defined above. This means that different codons may code for the same amino acid.

[0098] According to one embodiment of the invention the polynucleotide is "comprised in" SEQ ID NO: 3, 5, 11, 13, 15, 19, 21, 23 or 25, which means that the sequence has at least part of the sequence mentioned. According to another embodiment of the invention, the polynucleotide comprises a gene similar to that included in a microorganism having accession number DSM 16728, DSM 16729, DSM 17324, DSM 17323, DSM 17729, DSM 16726, DSM 16725, DSM 17325 or DSM 17667.

[0099] The novel proteins/polypeptides may be prepared as described above. The novel polynucleotides may be inserted into a vector, which is capable of expressing the polypeptide encoded by the heterologous sequence, and the vector may be inserted into a host cell capable of expressing said polypeptide. The host cell is preferably of the genus Trichoderma or Aspergillus.

[0100] A heterologous gene encoding the novel polypeptides has been introduced on a plasmid into an Escherichia coli strain having accession number DSM 16728, DSM 16729, DSM 17324, DSM 17323, DSM 17729, DSM 16726, DSM 16725, DSM 17325 or DSM 17667.

[0101] The novel enzymes may be components of an enzyme preparation. The enzyme preparation may comprise one or more of the novel polypeptides, and it may be e.g. in the form of spent culture medium, powder, granules or liquid. According to one embodiment of the invention it comprises cellobiohydrolase, endoglucanase, beta-glucosidase, and optionally xylanase activity and/or other enzyme activities. It may further comprise any conventional additives.

[0102] The novel enzymes may be applied in any process involving cellulolytic enzymes, such as in fuel, textile, detergent, pulp and paper, food, feed or beverage industry, and especially in hydrolysing cellulosic material for the production of biofuel comprising ethanol. In the pulp and paper industry they may be used to modify cellulosic fibre for example in treating kraft pulp, mechanical pulp, or recycled paper.

[0103] The invention is illustrated by the following non-limiting examples. It should be understood, however, that the embodiments given in the description above and in the examples are for illustrative purposes only, and that various changes and modifications are possible within the scope of the invention.

Example 1

Screening for Strains Expressing Cellulolytic Activity and their Cultivation for Purification

[0104] About 25 fungal strains from the Roal Oy culture collection were tested for cellulolytic activity including beta-glucosidases. After preliminary screening six strains were chosen for further studies. These were Thermoascus aurantiacus ALKO4239 and ALKO4242, Acremonium thermophilum ALKO4245, Talaromyces thermophilus ALKO4246 and Chaetomium thermophilum ALKO4261 and ALKO4265.

[0105] The strains ALKO4239, ALKO4242 and ALKO4246 were cultivated in shake flasks at 42.degree. C. for 7 d in the medium 3.times.B, which contains g/litre: Solka Floc cellulose 18, distiller's spent grain 18, oats spelt xylan 9, CaCO.sub.3 2, soybean meal 4.5, (NH.sub.4)HPO.sub.4 4.5, wheat bran 3.0, KH.sub.2PO.sub.4 1.5, MgSO.sub.4.H.sub.2O 1.5, NaCl 0.5, KNO.sub.3 0.9, locust bean gum 9.0, trace element solution #1 0.5, trace element solution #2 0.5 and Struktol (Stow, Ohio, USA) antifoam 0.5 ml; the pH was adjusted to 6.5. Trace element solution #1 has g/litre: MnSO.sub.4 1.6, ZnSO.sub.4.7H.sub.2O 3.45 and CoCl.sub.2.6H.sub.2O 2.0; trace element solution #2 has g/litre: FeSO.sub.4.7H.sub.2O 5.0 with two drops of concentrated H.sub.2SO.sub.4.

[0106] The strain ALKO4261 was cultivated in shake flasks in the medium 1.times.B, which has one third of each of the constituents of the 3.times.B medium (above) except it has same concentrations for CaCO.sub.3, NaCl and the trace elements. The strain was cultivated at 45.degree. C. for 7 d.

[0107] The strain ALKO4265 was cultivated in shake flasks in the following medium, g/l: Solka Floc cellulose 40, Pharmamedia.TM. (Traders Protein, Memphis, Tenn., USA) 10, corn steep powder 5, (NH.sub.4).sub.2SO.sub.4 5 and KH.sub.2PO.sub.4 15; the pH was adjusted to 6.5. The strain was cultivated at 45.degree. C. for 7 d.

[0108] After the cultivation the cells and other solids were collected by centrifugation down and the supernatant was recovered. For the shake flask cultivations, protease inhibitors PMSF (phenylmethyl-sulphonylfluoride) and pepstatin A were added to 1 mM and 10 .mu.g/ml, respectively. If not used immediately, the preparations were stored in aliquots at -20.degree. C.

[0109] For the estimation of the thermoactivity of the enzymes, assays were performed of the shake flask cultivation preparations at 50.degree. C., 60.degree. C., 65.degree. C., 70.degree. C. and 75.degree. C. for 1 h, in the presence of 100 .mu.g bovine serum albumin (BSA)/ml as a stabilizer. Preliminary assays were performed at 50.degree. C. and 65.degree. C. at two different pH values (4.8/5.0 or 6.0) in order to clarify, which pH was more appropriate for the thermoactivity assay.

[0110] All shake flask supernatants were assayed for the following activities:

[0111] Cellobiohydrolase I-like activity (`CBHI`) and the endoglucanase I-like activity (`EGI`):

[0112] These were measured in 50 mM Na-acetate buffer with 0.5 mM MUL (4-methylumbelliferyl-beta-D-lactoside) as the substrate. Glucose (100 mM) was added to inhibit any interfering beta-glucosidase activity. The liberated 4-methylumbelliferyl was measured at 370 nm. The `CBHI` and the `EGI` activities were distinguished by measuring the activity in the presence and absence of cellobiose (5 mM). The activity that is not inhibited by cellobiose represents the `EGI` activity and the remaining MUL activity represents the `CBHI` activity (van Tilbeurgh et al, 1988). The assay was performed at pH 5.0 or 6.0 (see below).

[0113] The endoglucanase (CMCase) activity:

[0114] This was assayed with 2% (w/v) carboxymethylcellulose (CMC) as the substrate in 50 mM citrate buffer essentially as described by Bailey and Nevalainen 1981; Haakana et al. 2004. Reducing sugars were measured with the DNS reagent. The assay was performed at pH 4.8 or 6.0 (see below).

[0115] Beta-glucosidase (BGU) activity:

[0116] This was assayed with 4-nitrophenyl-.beta.-D-glucopyranoside (1 mM) in 50 mM citrate buffer as described by Bailey and Nevalainen 1981. The liberated 4-nitrophenol was measured at 400 nm. The assay was performed at pH 4.8 or 6.0 (see below).

[0117] The relative activities of the enzymes are presented in FIG. 1A-B. The relative activities were presented by setting the activity at 60.degree. C. as 100% (FIG. 1A-B). All strains produced enzymes, which had high activity at high temperatures (65.degree. C.-75.degree. C.).

[0118] For protein purifications. ALKO4242 was also grown in a 2 litre bioreactor (Braun Biostat.RTM. B, Braun, Melsungen, Germany) in the following medium, g/litre: Solka Floc cellulose 40, soybean meal 10, NH.sub.4NO.sub.3 5, KH.sub.2PO.sub.4 5, MgSO.sub.4.7H.sub.2O 0.5, CaCl.sub.2.2H.sub.2O 0.05, trace element solution #1 0.5, trace element solution #2 0.5. The aeration was 1 vvm, antifoam control with Struktol, stirring 200-800 rpm and temperature at 47.degree. C. Two batches were run, one at pH 4.7.+-.0.2 (NH.sub.3/H.sub.2SO.sub.4) and the other with initial pH of pH 4.5. The cultivation time was 7 d. After the cultivation the cells and other solids were removed by centrifugation.

[0119] The strain ALKO4245 was grown in 2 litre bioreactor (Braun Biostat.RTM. B, Braun, Melsungen, Germany) in the following medium, g/litre: Solka Floc cellulose 40, corn steep powder 15, distiller's spent grain 5, oats spelt xylan 3, locust bean gum 3, (NH.sub.4).sub.2SO.sub.4 5 and KH.sub.2PO.sub.4 5. The pH range was 5.2.+-.0.2 (NH.sub.3/H.sub.2SO.sub.4), aeration 1 vvm, stirring 300-600 rpm, antifoam control with Struktol and the temperature 42.degree. C. The cultivation time was 4 d.

Purification and Characterization of Cellobiohydrolases from Acremonium thermophilum ALKO4245 and Chaetomium thermophilum ALKO4265

[0122] Acremonium thermophilum ALKO4245 and Chaetomium thermophilum ALKO4265 were grown as described in Example 1. The main cellobiohydrolases were purified using p-aminobenzyl 1-thio-.beta.-cellobioside-based affinity column, prepared as described by Tomme et al., 1988.

[0123] The culture supernatants were first buffered into 50 mM sodium acetate buffer pH 5.0, containing 1 mM .delta.-gluconolactone and 0.1 M glucose in order to retard ligand hydrolysis in the presence of .beta.-glucosidases. Cellobiohydrolases were eluted with 0.1 M lactose and finally purified by gel filtration chromatography using Superdex 200 HR 10/30 columns in the AKTA system (Amersham Pharmacia Biotech). The buffer used in gel filtration was 50 mM sodium phosphate pH 7.0, containing 0.15 M sodium chloride.

[0124] Purified cellobiohydrolases were analysed by SDS-polyacrylamide gel electrophoresis and the molecular mass of both proteins was determined to be approximately 70 kDa evaluated on the basis of the molecular mass standards (Low molecular weight calibration kit, Amersham Biosciences). Purified Acremonium and Chaetomium cellobiohydrolases were designated as At Cel7A and Ct Cel7A, respectively, following the scheme in Henrissat et al. (1998) (Henrissat, 1991; Henrissat and Bairoch, 1993).

[0125] The specific activity of the preparations was determined using 4-methylumbelliferyl-.beta.-D-lactoside (MUL), 4-methylumbelliferyl-.beta.-D-cellobioside (MUG2) or 4-methylumbelliferyl-.beta.-D-cellotrioside (MUG3) as substrate (van Tilbeurgh et al., 1988) in 0.05 M sodium citrate buffer pH 5 at 50.degree. C. for 10 min. Endoglucanase and xylanase activities were determined by standard procedures (according to IUPAC, 1987) using carboxymethyl cellulose (CMC) and birch glucuronoxylan (Bailey et al., 1992) as substrates. Specific activity against Avicel was calculated on the basis of reducing sugars formed in a 24 h reaction at 50.degree. C., pH 5.0, with 1% substrate and 0.25 .mu.M enzyme dosage. The protein content of the purified enzyme preparations was measured according to Lowry et al., 1951. To characterize the end products of hydrolysis, soluble sugars liberated in 24 h hydrolysis experiment, as described above, were analysed by HPLC (Dionex). Purified cellobiohydrolase I (CBHI/Cel7A) of Trichoderma reesei was used as a reference.

[0126] The specific activities of the purified enzymes and that of T. reesei CBHI/Cel7A are presented in Table 1. The purified At Cel7A and Ct Cel7A cellobiohydrolases possess higher specific activities against small synthetic substrates as compared to T. reesei CBHI/Cel7A. The specific activity against Avicel was clearly higher with the herein disclosed enzymes. Low activities of the purified enzyme preparations against xylan and CMC may either be due to the properties of the proteins themselves, or at least partially to the remaining minor amounts of contaminating enzymes. The major end product of cellulose hydrolysis by all purified enzymes was cellobiose which is typical to cellobiohydrolases.

[0127] Thermal stability of the purified cellobiohydrolases was determined at different temperatures. The reaction was performed in the presence of 0.1% BSA at pH 5.0 for 60 min using 4-methylumbelliferyl-.beta.-D-lactoside as substrate. C. thermophilum ALKO4265 CBH/Cel7A and A. thermophilum ALKO4245 CBH/Cel7A were stable up to 65.degree. and 60.degree. C., respectively. The T. reesei reference enzyme (CBHI/Cel7A) retained 100% of activity up to 55.degree. C.

Construction of Genomic Libraries for Thermoascus aurantiacus, Chaetomium thermophilum and Acremonium thermophilum

[0169] The genomic library of Chaetomium thermophilum ALKO4265 and Acremonium thermophilum ALKO4245 were made to Lambda DASH.RTM.II vector (Stratagene, USA) according to the instructions from the supplier. The chromosomal DNAs, isolated by the method of Raeder and Broda (1985), were partially digested with Sau3A. The digested DNAs were size-fractionated and the fragments of the chosen size (.apprxeq.5-23 kb) were dephosphorylated and ligated to the BamHI digested lambda vector arms. The ligation mixtures were packaged using Gigapack III Gold packaging extracts according to the manufacturer's instructions (Stratagene, USA). The titers of the Chaetomium thermophilum and Acremonium thermophilum genomic libraries were 3.6.times.10.sup.6 pfu/ml and 3.7.times.10.sup.5 pfu/ml and those of the amplified libraries were 6.5.times.10.sup.10 pfu/ml and 4.2.times.10.sup.8 pfu/ml, respectively.

[0170] Lambda FIX.RTM. II/Xho I Partial Fill-In Vector Kit (Stratagene, USA) was used in the construction of the genomic libraries for Thermoascus aurantiacus ALKO4242 and Chaetomium thermophilum ALKO4261 according to the instructions from the supplier. The chromosomal DNAs, isolated by the method of Raeder and Broda (1985), were partially digested with Sau3A. The digested DNAs were size-fractionated and the fragments of the chosen size (.apprxeq.6-23 kb) were filled-in and ligated to the XhoI digested Lambda FIX II vector arms. The ligation mixtures were packaged using Gigapack III Gold packaging extracts according to the manufacturer's instructions (Stratagene, USA). The titers of the Thermoascus aurantiacus ALKO4242 and Chaetomium thermophilum ALKO4261 genomic libraries were 0.2.times.10.sup.6 and 0.3.times.10.sup.6 pfu/ml and those of the amplified libraries were 1.8.times.10.sup.9 and 3.8.times.10.sup.9 pfu/ml, respectively.

Cloning of the Cellobiohydrolase (cbh/cel7) Genes from Thermoascus aurantiacus, Chaetomium thermophilum and Acremonium thermophilum

[0171] Standard molecular biology methods were used in the isolation and enzyme treatments of DNA (plasmids, DNA fragments), in E. coli transformations, etc. The basic methods used are described in the standard molecular biology handbooks, e.g., Sambrook et al. (1989) and Sambrook and Russell (2001).

[0172] The probes for screening the genomic libraries which were constructed as described in Example 12 were amplified by PCR using the Thermoascus aurantiacus ALKO4242, Chaetomium thermophilum ALKO4265 and Acremonium thermophilum ALKO4245 genomic DNAs as templates in the reactions. Several primers tested in PCR reactions were designed according to the published nucleotide sequence (WO 03/000941, Hong et al., 2003b). The PCR reaction mixtures contained 50 mM Tris-HCl, pH 9.0, 15 mM (NH.sub.4).sub.2SO.sub.4, 0.1% Triton X-100, 1.5 mM MgCl.sub.2, 0.2 mM dNTPs, 5 .mu.M each primer and 1 units of Dynazyme EXT DNA polymerase (Finnzymes, Finland) and .apprxeq.0.5-1 .mu.g of the genomic DNA. The conditions for the PCR reactions were the following: 5 min initial denaturation at 95.degree. C., followed by 30 cycles of 1 min at 95.degree. C., either 1 min annealing at 62.degree. C. (.+-.8.degree. C. gradient) for Thermoascus ALKO4242 and Chaetomium ALKO4265 templates or 1 min annealing at 58.degree. C. (.+-.6.degree. C. gradient) for Acremonium ALKO4245 template, 2 min extension at 72.degree. C. and a final extension at 72.degree. C. for 10 min.

[0173] DNA products of the expected sizes (calculated from published cbh sequences) were obtained from all genomic templates used. The DNA fragments of the expected sizes were isolated from the most specific PCR reactions and they were cloned to pCR.RTM. Blunt-TOPO.RTM. vector (Invitrogen, USA). The inserts were characterized by sequencing and by performing Southern blot hybridizations to the genomic DNAs digested with several restriction enzymes. The PCR fragments, which were chosen to be used as probes for screening of the Thermoascus aurantiacus, Chaetomium thermophilum and Acremonium thermophilum genomic libraries are presented in Table 6.

[0174] The deduced amino acid sequences from all these probes had homology to several published CBH sequences (BLAST program, version 2.2.9 at NCBI, National Center for Biotechnology Information; Altschul et al., 1990) of glycoside hydrolase family 7 (Henrissat, 1991; Henrissat and Bairoch, 1993).

[0175] The inserts from the plasmids listed in Table 6 were labeled with digoxigenin according to the supplier's instructions (Roche, Germany), and the amplified genomic libraries (2.times.10.sup.5-3.times.10.sup.5 plaques) were screened with the labeled probe fragments. The hybridization temperature for the filters was 68.degree. C. and the filters were washed 2.times.5 min at RT using 2.times.SSC-0.1% SDS followed by 2.times.15 min at 68.degree. C. using 0.1.times.SSC-0.1% SDS with the homologous probes used. Several positive plaques were obtained from each of the hybridizations. In screening of the Acremonium ALKO4245 genomic libraries, some of the positive plaques were strongly hybridizing to the probe in question but, in addition, there was an amount of plaques hybridizing more weakly to the probes. This suggested that other cellobiohydrolase gene(s) might be present in the genome, causing cross-reaction. From four to five strongly hybridizing plaques were purified from Thermoascus ALKO4242 and Chaetomium ALKO4265 genomic library screenings. In the case of the Acremonium thermophilum ALKO4245, four out of six purified plaques hybridized weakly by the probe used. The phage DNAs were isolated and characterized by Southern blot hybridizations. The chosen restriction fragments hybridizing to the probe were subcloned to pBluescript II KS+ vector and the relevant regions of the clones were sequenced.

[0176] In total four cbh/cel7 genes were cloned; one from Thermoascus aurantiacus ALKO4242, one from Chaetomium thermophilum ALKO4265 and two from Acremonium thermophilum ALKO4245 (at the early phase of the work, these had the codes At_cbh_C and At_cbh_A, and were then designated as At cel7A and At cel7B, respectively). Table 7 summarizes the information on the probes used for screening the genes, the phage clones from which the genes were isolated, the chosen restriction fragments containing the full-length genes with their promoter and terminator regions, the plasmid names, and the DSM deposit numbers for the E. coli strains carrying these plasmids.

[0177] The relevant information on the genes and the deduced protein sequences (SEQ ID NO: 1-8) are summarized in Table 8 and Table 9, respectively.

[0178] The peptide sequences of the purified CBH proteins from Chaetomium thermophilum ALKO4265 and Acremonium thermophilum ALKO4245 (Table 2) were found from the deduced amino acid sequences of the clones containing the Ct cel7A and At cel7A genes. Thus, it could be concluded that the genes encoding the purified CBH/Cel7 proteins from Chaetomium thermophilum and Acremonium thermophilum were cloned.

[0179] The deduced amino acid sequences of Thermoascus aurantiacus Cel7A and Acremonium thermophilum Cel7A (core, without the CBD) were most homologous to each other (analyzed by Needleman-Wunsch global alignment, EMBOSS 3.0.0 Needle, with Matrix EBLOSUM62, Gap Penalty 10.0 and Extend Penalty 0.5; Needleman and Wunsch, 1970). In addition, the deduced Acremonium thermophilum Cel7A had a lower identity to the deduced Chaetomium thermophilum Cel7A. The Acremonium thermophilum Cel7B was most distinct from the CBH/Cel7 sequences of the invention.

[0180] The deduced Chaetomium Cel7A sequence possessed the highest identities (analyzed by Needleman-Wunsch global alignment, EMBOSS Needle, see above) to polypeptides of Chaetomium thermophilum, Scytalidium thermophilum and Thielavia australiensis CBHI described in WO 03/000941. Similarly, the deduced Thermoascus aurantiacus Cel7A sequence was highly identical to the published CBHI of the Thermoascus aurantiacus (WO 03/000941, Hong et al., 2003b). Acremonium thermophilum Cel7B had significantly lower identities to the previously published sequences, being more closely related to the CBHI polypeptide from Oryza sativa. The highest homologies of the deduced Acremonium thermophilum Cel7A sequence were to Exidia gladulosa and Acremonium thermophilum CBHI polynucleotides (WO 03/000941). The alignment indicates that the cloned Thermoascus aurantiacus ALKO4242, Chaetomium thermophilum ALKO4265 and Acremonium thermophilum ALKO4245 sequences encode the CBH proteins having high homology to the polypeptides of the glycoside hydrolase family 7, therefore these were designated as Cel7A or Cel7B (Henrissat et al. 1998).

[0181] The comparison of the deduced amino acid sequences of the cbh/cel7 genes from Thermoascus aurantiacus ALKO4242, Chaetomium thermophilum ALKO4265 and Acremonium thermophilum ALKO4245 Thielavia to each other, and further to the sequences found from the databases, are shown in Table 10.

Production of Recombinant CBH/Cel7 Proteins in Trichoderma reesei

[0182] Expression plasmids were constructed for production of the recombinant CBH/Cel7 proteins from Thermoascus aurantiacus (Ta Cel7A), Chaetomium thermophilum (Ct Cel7A) and Acremonium thermophilum (At Cel7A, At Cel7B; at early phase of the work these proteins had the temporary codes At CBH_C and At CBH_A, respectively). The expression plasmids constructed are listed in Table 11. The recombinant cbh/cel7 genes, including their own signal sequences, were exactly fused to the T. reesei cbh1 (cel7A) promoter by PCR. The transcription termination was ensured by the T. reesei cel7A terminator and the A. nidulans amdS marker gene was used for selection of the transformants as described in Paloheimo et al. (2003). The linear expression cassettes (FIG. 2), were isolated from the vector backbones after EcoRI digestion and were transformed into T. reesei A96 and A98 protoplasts (both strains have the genes encoding the four major cellulases CBHI/Cel7A, CBHII/Cel6A, EGI/Cel7B and EGII/Cel5A deleted). The transformations were performed as in Penttila et al. (1987) with the modifications described in Karhunen et al. (1993), selecting with acetamide as a sole nitrogen source. The transformants were purified on selection plates through single conidia prior to sporulating them on PD.

[0183] The CBH/Cel7 production of the transformants was analysed from the culture supernatants of the shake flask cultivations (50 ml). The transformants were grown for 7 days at 28.degree. C. in a complex lactose-based cellulase-inducing medium (Joutsjoki et al. 1993) buffered with 5% KH.sub.2PO.sub.4. The cellobiohydrolase activity was assayed using 4-methylumbelliferyl-.beta.-D-lactoside (MUL) substrate according to van Tilbeurgh et al., 1988. The genotypes of the chosen transformants were confirmed by using Southern blots in which several genomic digests were included and the respective expression cassette was used as a probe. Heterologous expression of the Ta Cel7A, Ct Cel7A, At Cel7A and At Cel7B proteins was analyzed by SDS-PAGE with subsequent Coomassive staining. The findings that no cellobiohydrolase activity or heterologous protein production in SDS-PAGE could be detected for the At Cel7B transformants containing integrated expression cassette, suggest that At Cel7B is produced below detection levels in Trichoderma using the described experimental design.

[0184] The recombinant CBH/Cel7 enzyme preparations were characterized in terms of pH optimum and thermal stability. The pH optimum of the recombinant CBH/Cel7 proteins from Thermoascus aurantiacus, Chaetomium thermophilum, and Acremonium thermophilum were determined in the universal McIlvaine buffer within a pH range of 3.0-8.0 using 4-methylumbelliferyl-.beta.-D-lactoside (MUL) as a substrate (FIG. 3A). The pH optimum for Ct Cel7A and At Cel7A enzymes is at 5.5, above which the activity starts to gradually drop.

[0185] The pH optimum of the recombinant crude Ta Cel7A is at 5.0 (FIG. 3A). Thermal stability of the recombinant Cel7 enzymes was determined by measuring the MUL activity in universal McIlvaine buffer at the optimum pH with reaction time of 1 h. As shown from the results Ta Cel7A and Ct Cel7A retained more than 60% of their activities at 70.degree. C., whereas At Cel7A showed to be clearly less stable at the higher temperatures (65.degree. C.) (FIG. 3B).

[0186] The chosen CBH/Cel7 transformants were cultivated in lab bioreactors at 28.degree. C. in the medium indicated above for 3-4 days with pH control 4.4.+-.0.2 (NH.sub.3/H.sub.3PO.sub.4) to obtain material for the application tests. The supernatants were recovered by centrifugation and filtering through Seitz-K 150 and EK filters (Pall SeitzSchenk Filtersystems GmbH, Bad Kreuznach, Germany).

Production of the Recombinant Thermoascus aurantiacus Cel7A+CBD Fusion Proteins in T. reesei

[0187] Thermoascus aurantiacus Cel7A (AF478686, Hong et al., 2003b; SEQ ID. NO: 1) was fused to linker and CBD of Trichoderma reesei CBHI/Cel7A (AR088330, Srisodsuk et al. 1993) (=Tr CBD) followed by the production of the fusion protein (SEQ ID NO: 28 corresponding nucleic acid SEQ ID. NO: 27) in the T. reesei as was described in FI20055205/US 11/119,526; filed Apr. 29, 2005. In addition, Thermoascus aurantiacus Cel7A was fused to linker and CBD of Chaetomium thermophilum Cel7A (SEQ ID. NO: 7) (Ct CBD). For that purpose, the coding sequence of the linker and the CBD of Chaetomium thermophilum Cel7A were synthesized by PCR using following primers:

TABLE-US-00016 (forward sequence) 5'-TTAAACATATGTTATCTACTCCAACATCAAGGTCGGACCCATCGG CTC-GACCGTCCCTGGCCTTGAC-3' And (reverse sequence) 5'-TATATGCGGCCGCAAGCTTTACCATCAAGTTACTCCAGCAAATCA GGG-AACTG-3'.

[0188] The PCR reaction mixture contained 1.times. DyNAzyme.TM. EXT reaction buffer (Finnzymes, Finland), 15 mM Mg.sup.2+, 0.2 mM dNTPs, 2 .mu.M of each primer, 0.6 units of DyNAzyme.TM. EXT DNA polymerase (Finnzymes, Finland), and approximately 75 ng/30 .mu.l of template DNA, containing full-length cel7A gene from the Chaetomium thermophilum. The conditions for the PCR reaction were the following: 2 min initial denaturation at 98.degree. C., followed by 30 cycles of 30 sec at 98.degree. C., 30 sec annealing at 68.degree. C. (.+-.4.degree. C. gradient), 30 sec extension at 72.degree. C. and a final extension at 72.degree. C. for 10 min. The specific DNA fragment in PCR reaction was obtained at annealing temperature range from 64.degree. C. to 68.5.degree. C. The synthesized CBD fragment of the Chaetomium thermophilum was ligated after Thermoascus aurantiacus cel7A gene resulting in a junction point of GPIGST between the domains. The PCR amplified fragment in the plasmid was confirmed by sequencing (SEQ ID. NO: 29). The constructed fusion cel7A gene was exactly fused to the T. reesei cbh1 (cel7A) promoter. The transcription termination was ensured by the T. reesei cel7A terminator and the A. nidulans amdS marker gene was used for selection of the transformants as described in Paloheimo et al. (2003).

[0189] The linear expression cassette was isolated from the vector backbone after NotI digestion and was transformed to T. reesei A96 protoplasts. The transformations were performed as in Penttila et al. (1987) with the modifications described in Karhunen et al. (1993), selecting with acetamide as a sole nitrogen source. The transformants were purified on selection plates through single conidia prior to sporulating them on PD.

[0190] Thermoascus aurantiacus Cel7A+CBD (SEQ ID. NO: 28 and 30) production of the transformants was analyzed from the culture supernatants of the shake flask cultivations (50 ml). The transformants were grown for 7 days in a complex cellulase-inducing medium (Joutsjoki et al. 1993) buffered with 5% KH.sub.2PO.sub.4 at pH 5.5. The cellobiohydrolase activity was assayed using 4-methylumbelliferyl-.beta.-D-lactoside (MUL) substrate according to van Tilbeurgh et al., 1988. The genotypes of the chosen transformants were confirmed by using Southern blots in which several genomic digests were included and the expression cassette was used as a probe. The SDS-PAGE analyses showed that the recombinant Thermoascus aurantiacus Cel7A+CBD enzymes were produced as stable fusion proteins in T. reesei.

[0191] The chosen transformant producing the Ta Cel7A+Tr CBD fusion protein (SEQ ID. NO: 28) was also cultivated in 2 litre bioreactor at 28.degree. C. in the medium indicated above for 3-4 days with pH control 4.4.+-.0.2 (NH.sub.3/H.sub.3PO.sub.4) to obtain material for the application tests. The supernatants were recovered by centrifugation and filtering through Seitz-K 150 and EK filters (Pall SeitzSchenk Filtersystems GmbH, Bad Kreuznach, Germany).

Comparison of the Michaelis-Menten and Cellobiose Inhibition Constants of Purified Recombinant Cellobiohydrolases

[0192] The Michaelis-Menten and cellobiose inhibition constants were determined from the cellobiohydrolases produced heterologously in T. reesei (Examples 14 and 15). The enzymes were purified as described in Example 2. Protein concentrations of purified enzymes were measured by their absorption at 280 nm using a theoretical molar extinction co-efficient, which were calculated from the amino acid sequences (Gill and von Hippel, 1989).

[0193] Kinetic constants (Km and kcat values) and cellobiose inhibition constant (Ki) for Tr CBHI/Cel7A, Ta CBH/Cel7A, At CBH/Cel7A and Ct CBH/Cel7A, were measured using CNPLac (2-Chloro-4-nitrophenyl-.beta.-D-lactoside) as substrate at ambient temperature (22.degree. C.) in 50 mM sodium phosphate buffer, pH 5.7. For the determination of the inhibition constant (Ki), eight different substrate concentrations (31-4000 .mu.M) in the presence of a range of five inhibitor concentrations (0-100 .mu.M or 0-400 .mu.M), which bracket the Ki value, were used. All experiments were performed in microtiter plates and the total reaction volume was 200 .mu.l. The initial rates were in each case measured by continuous monitoring the release of the chloro-nitrophenolate anion (CNP, 2-Chloro-4-nitrophenolate) through measurements at 405 nm using Varioscan (Thermolabsystems) microtiter plate reader. The results were calculated from CNP standard curve (from 0 to 100 .mu.M). Enzyme concentrations used were: Tr CBHI/Cel7A 2.46 .mu.M, Ta CBH/Cel7A 1.58 .mu.M, Ct CBH/Cel7A 0.79 .mu.M and At CBH/Cel7A 3 .mu.M. The Km and kcat constants were calculated from the fitting of the Michaelis-Menten equation using the programme of Origin. Lineweaver-Burk plots, replots (LWB slope versus [Glc2; cellobiose]) and Hanes plots were used to distinguish between competitive and mixed type inhibition and to determine the inhibition constants (Ki).

[0194] The results from the kinetic measurements are shown in Table 12 and Table 13. As can be seen, Ct CBH/Cel7A has clearly the higher turnover number (kcat) on CNPLac and also the specificity constant (kcat/Km) is higher as compared to CBHI/Cel7A of T. reesei. Cellobiose (Glc2) is a competitive inhibitor for all the measured cellulases, and the Tr CBHI/Cel7A (used as a control) has the strongest inhibition (i.e. the lowest Ki value) by cellobiose. The At CBH/Cel7A had over 7-fold higher inhibition constant as compared to that of Tr CBHI/Cel7A. These results indicate that all three novel cellobiohydrolases could work better on cellulose hydrolysis due to decreased cellobiose inhibition as compared to Trichoderma reesei Cel7A cellobiohydrolase I.

Hydrolysis of Crystalline Cellulose (Avicel) by the Recombinant Cellobiohydrolases

[0195] The purified recombinant cellobiohydrolases Ct Cel7A, Ta Cel7A, Ta Cel7A+Tr CBD, Ta Cel7A+Ct CBD, At Cel7A as well as the core version of Ct Cel7A (see below) were tested in equimolar amounts in crystalline cellulose hydrolysis at two temperatures, 45.degree. C. and 70.degree. C.; the purified T. reesei Tr Cel7A and its core version (see below) were used as comparison.

[0196] The crystalline cellulose (Ph 101, Avicel; Fluka, Bucsh, Switzerland) hydrolysis assays were performed in 1.5 ml tube scale 50 mM sodium acetate, pH 5.0. Avicel was shaken at 45.degree. C. or at 70.degree. C., with the enzyme solution (1.4 .mu.M), and the final volume of the reaction mixture was 325 .mu.l. The hydrolysis was followed up to 24 hours taking samples at six different time points and stopping the reaction by adding 163 .mu.l of stop reagent containing 9 vol of 94% ethanol and 1 vol of 1 M glycine (pH 11). The solution was filtered through a Millex GV13 0.22 .mu.m filtration unit (Millipore, Billerica, Mass., USA). The formation of soluble reducing sugars in the supernatant was determined by para-hydroxybenzoic-acidhydrazide (PAHBAH) method (Lever, 1972) using a cellobiose standard curve (50 to 1600 .mu.M cellobiose). A freshly made 0.1 M PAHBAH (Sigma-Aldrich, St. Louis, Mo., USA) in 0.5 M NaOH (100 .mu.l) solution was added to 150 .mu.l of the filtered sample and boiled for 10 minutes after which the solution was cooled on ice. The absorbance of the samples at 405 nm was measured.

[0197] The core versions of the cellobiohydrolases harboring a CBD in their native form were obtained as follows: Ct Cel7A and Tr Cel7A were exposed to proteolytic digestion to remove the cellulose-binding domain. Papain (Papaya Latex, 14 U/mg, Sigma) digestion of the native cellobiohydrolases was performed at 37.degree. C. for 24 h in a reaction mixture composed of 10 mM L-cystein and 2 mM EDTA in 50 mM sodium acetate buffer (pH 5.0) with addition of papain (two papain concentrations were tested: of one fifth or one tenth amount of papain of the total amount of the Cel7A in the reaction mixture). The resultant core protein was purified with DEAE Sepharose FF (Pharmacia, Uppsala, Sweden) anion exchange column as described above. The product was analysed in SDS-PAGE.

[0198] The hydrolysis results at 45.degree. C. and 70.degree. C. are shown in FIG. 4A-B and FIG. 5A-B, respectively. The results show clearly that all the cellobiohydrolases show faster and more complete hydrolysis at both temperatures as compared to the state-of-art cellobiohydrolase T. reesei Cel7A. At 70.degree. C. the thermostable cellobiohydrolases from Thermoascus aurantiacus ALKO4242 and Chaetomium thermophilum ALKO4265 are superior as compared to the T. reesei Cel7A, also in the case where the Thermoascus Cel7A core is linked to the CBD of T. reesei Cel7A (Ta Cel7A+Tr CBD). It was surprising that the cellobiohydrolases isolated and cloned in this work are superior, when harboring a CBD, in the rate and product formation in crystalline cellulose hydrolysis also at the conventional hydrolysis temperature of 45.degree. C. when compared to the state-of-art cellobiohydrolase T. reesei Cel7A (CBHI) at the same enzyme concentration. The results are also in agreement with those enzyme preparations (At Cel7A and Ct Cel7A), which were purified from the original hosts and tested in Avicel hydrolysis (50.degree. C., 24 h) (Example 2, Table 1).

Cloning of Acremonium thermophilum ALKO4245, Chaetomium thermophilum ALKO4261, and Thermoascus aurantiacus ALKO4242 Endoglucanase Genes

[0199] Standard molecular biology methods were used as described in Example 13. The construction of the Acremonium, Chaetomium, and Thermoascus genomic libraries has been described in Example 12.

[0200] The peptides derived from the purified Acremonium and Chaetomium endoglucanases shared homology with several endoglucanases of glycosyl hydrolase family 45 such as Melanocarpus albomyces Cel45A endoglucanase (AJ515703) and Humicola insolens endoglucanase (A35275), respectively. Peptides derived from the Thermoascus endoglucanase shared almost 100% identity with the published Thermoascus aurantiacus EG1 endoglucanase sequence (AF487830). To amplify a probe for screening of the Acremonium and Chaetomium genomic libraries, degenerate primers were designed on the basis of the peptide sequences. The order of the peptides in the protein sequence and the corresponding sense or anti-sense nature of the primers was deduced from the comparison with the homologous published endoglucanases. Primer sequences and the corresponding peptides are listed in Table 14. Due to almost 100% identity of the Thermoascus peptides with the published sequence, the endoglucanase gene was amplified by PCR directly from the genomic DNA.

TABLE-US-00019 TABLE 14 Oligonucleotides synthesized and used as PCR primers to amplify a probe for screening of Acremonium thermophilum cel45A (EG_40) and Chaetomium thermophilum cel7B (EG_54) gene from the corresponding genomic libraries.

[0201] The Acremonium thermophilum cel45A gene specific probe to screen the genomic library was amplified with the forward (TAYTGGGAYTGYTGYAARCC) and reverse (RTTRTCNGCRTTYTGRAACCA) primers using genomic DNA as a template. The PCR reaction mixtures contained 50 mM Tris-HCl, pH 9.0, 15 mM (NH.sub.4).sub.2SO.sub.4, 0.1% Triton X-100, 1.5 mM MgCl.sub.2, 0.1 mM dNTPs, 0.5 .mu.g each primer, 1 unit of Dynazyme EXT DNA polymerase (Finnzymes, Finland) and approximately 0.5 .mu.g of Acremonium genomic DNA. The conditions for PCR reactions were the following: 5 min initial denaturation at 95.degree. C., followed by 30 cycles of 1 min at 95.degree. C., 1 min annealing at 50-60.degree. C., 2 min extension at 72.degree. C. and a final extension at 72.degree. C. for 10 min. For amplification of the Chaetomium thermophilum cel7B gene (coding for Ct EG 54) specific probe, a forward primer (GGAATTCGAYCARACNGARCARTA) and a reverse primer (GCAAGCTTCGRCARAARTCRTCRTT) were used. The PCR reaction mixtures contained 10 mM Tris-HCl, pH 8.8, 50 mM KCl, 0.1% Triton X-100, 1.5 mM MgCl.sub.2, 0.2 mM dNTPs, 250 pmol each primer, 2 unit of Dynazyme II DNA polymerase (Finnzymes, Finland) and approximately 2 .mu.g of Chaetomium genomic DNA. The conditions for PCR reaction were as described above, except that annealing was performed at 45-50.degree. C.

[0202] Two PCR products were obtained from the Acremonium PCR reaction. DNA fragments of about 0.6 kb and 0.8 kb were isolated from agarose gel and were cloned into the pCR4-TOPO.RTM. TA vector (Invitrogen, USA) resulting in plasmids pALK1710 and pALK1711, respectively. The DNA products were characterized by sequencing and by performing Southern blot hybridizations to the genomic Acremonium DNA digested with several restriction enzymes. The hybridization patterns obtained with the two fragments in stringent washing conditions suggest that two putative endoglucanase genes could be screened from the Acremonium genomic library. The deduced amino acid sequences of both PCR products have homology to several published endoglucanase sequences of glycosyl hydrolase family 45 (BLAST program, National Center for Biotechnology Information; Altschul et al., 1990).

[0203] One PCR product of expected size (estimated from the homologous Humicola insolens endoglucanase sequence, A35275) was obtained from the Chaetomium PCR reaction. This DNA fragment of about 0.7 kb was cloned into the pCR4-TOPO.RTM. TA vector (Invitrogen, USA) resulting in plasmid pALK2005 and analyzed as described above. The deduced amino acid sequence of the PCR product has homology to several published cellulase sequences of glycosyl hydrolase family 7 (BLAST program, version 2.2.9 at NCBI, National Center for Biotechnology Information; Altschul et al., 1990).

[0204] The insert from plasmids pALK1710, pALK1711, and pALK2005 was isolated by restriction enzyme digestion and labeled with digoxigenin according to the supplier's instructions (Roche, Germany). About 1-2.times.10.sup.5 plaques from the amplified Acremonium or Chaetomium genomic library were screened. The temperature for hybridisation was 68.degree. C. and the filters were washed 2.times.5 min at RT using 2.times.SSC-0.1% SDS followed by 2.times.15 min at 68.degree. C. using 0.1.times.SSC-0.1% SDS. Several positive plaques were obtained, of which five to six strongly hybridizing plaques were purified from each screening. Phage DNAs were isolated and analysed by Southern blot hybridization. Restriction fragments hybridizing to the probe were subcloned into the pBluescript II KS+ vector (Stratagene, USA) and the relevant parts were sequenced. In all cases the subcloned phage fragment contains the full-length gene of interest. Table 15 summarises the information of the probes used for screening of the endoglucanase genes, phage clones from which the genes were isolated, chosen restriction fragments containing the full-length genes with their promoter and terminator regions, names of plasmids containing the subcloned phage fragment, and the deposit numbers in the Deutsche Sammlung von Mikroorganismen und Zellkulturen GmbH culture collection (DSM) for E. coli strains carrying these plasmids.

[0205] Thermoascus aurantiacus cel5A gene (coding for EG_28) (SEQ ID NO: 9) was amplified directly from the isolated genomic DNA by PCR reaction. The forward (ATTAACCGCGGACTGCGCATCATGAAGCTCGGCTCTCTCGTGCTC) and reverse (AACTGAGGCATAGAAACTGACGTCATATT) primers that were used for amplification were designed on the basis of the published T. aurantiacus eg1 gene (AF487830). The PCR reaction mixtures contained 1.times. Phusion HF buffer, 0.3 mM dNTPs, 0.5 .mu.M of each primer, 2 units of Phusion.TM. DNA polymerase (Finnzymes, Finland) and approximately 0.25 .mu.g of Thermoascus genomic DNA. The conditions for PCR reactions were the following: 5 min initial denaturation at 95.degree. C., followed by 25 cycles of 30 s at 95.degree. C., 30 s annealing at 57-67.degree. C., 2.5 min extension at 72.degree. C. and a final extension at 72.degree. C. for 5 min. The amplified 1.3 kb product containing the exact gene (from START to STOP codon) was cloned as a SacII-PstI fragment into the pBluescript II KS+ vector. Two independent clones were sequenced and one clone was selected and designated as pALK1926. The deposit number of the E. coli strain containing pALK1926 in the Deutsche Sammlung von Mikroorganismen und Zellkulturen GmbH culture collection is DSM 17326.

[0206] Relevant information of the genes and the deduced protein sequences (SEQ ID NO: 9-16) are summarized in Table 16 and Table 17, respectively. Peptide sequences of the purified Acremonium EG_40 (gene At cel45A), Chaetomium EG_54 (gene Ct cel7B), and Thermoascus EG_28 (gene Ta cel5A) endoglucanases were found in the corresponding deduced amino acid sequences of the cloned genes confirming that appropriate genes were cloned.

[0207] The deduced protein sequences of Acremonium EG_40 (At Cel45A) and EG_40_like (At Cel45B), Chaetomium EG_54 (Ct Cel7B), and Thermoascus EG_28 (Ta Cel5A) endoglucanases share homology with cellulases of glycosyl hydrolase family 45 (Acremonium), family 7 (Chaetomium), and family 5 (Thermoascus), thus identifying the isolated genes as members of these gene families. The closest homologies of the Acremonium endoglucanases EG_40/Cel45A and EG_40_like/Cel45B are endoglucanases of Thielavia terrestris (CQ827970, 77.3% identity) and Myceliophthora thermophila (AR094305, 66.9% identity), respectively (Table 18). The two isolated Acremonium family 45 endoglucanases share only an identity of 53.7% with each other. Of these enzymes only EG 40/Cel45A contains a cellulose binding domain (CBD).

[0208] The closest homology for the predicted protein sequence of Chaetomium EG_54/Cel7B endoglucanase is found in the Melanocarpus albomyces Cel7A cellulase sequence (AJ515704). The identity between these two protein sequences is 70.6%.

[0209] The protein sequence of the isolated Thermoascus aurantiacus endoglucanase is completely identical with that of the published T. aurantiacus EGI (AF487830, Table 18). The closest homology was found in a .beta.-glucanase sequence of Talaromyces emersonii (AX254752, 71.1% identity).

Production of Recombinant Endoglucanases in Trichoderma reesei

[0210] Expression plasmids were constructed for production of the recombinant Acremonium EG_40/Cel45A, EG_40_like/Cel45B, and Thermoascus EG_28/Cel5A proteins as described in Example 14. Linear expression cassettes (Table 19) were isolated from the vector backbone by restriction enzyme digestion, transformed into T. reesei A96 and transformants purified as described in Example 14.

[0211] The endoglucanase production of the transformants was analyzed from the culture supernatants of shake flask cultivations (50 ml). Transformants were grown as in Example 14 and the enzyme activity of the recombinant protein was measured from the culture supernatant as the release of reducing sugars from carboxymethylcellulose (2% (w/v) CMC) at 50.degree. C. in 50 mM citrate buffer pH 4.8 essentially as described by Bailey and Nevalainen 1981; Haakana et al. 2004. Production of the recombinant proteins was also detected from culture supernatants by SDS-polyacrylamide gel electrophoresis. Acremonium EG_40-specific polyclonal antibodies were produced in rabbits (University of Helsinki, Finland). The expression of EG_40 was verified by Western blot analysis with anti-EG_40 antibodies using the ProtoBlot Western blot AP system (Promega). The genotypes of the chosen transformants were analysed by Southern blotting using the expression cassette as a probe.

[0212] The pH optimum of the heterologously produced endoglucanases was determined in the universal McIlvaine's buffer within a pH range of 4.0-8.0 using carboxymethylcellulose as substrate. As shown in FIG. 6A the broadest pH range (4.5-6.0) is that of the Acremonium EG_40/Cel45A protein, the optimum being at pH 5.5. The pH optima for the other heterologously produced endoglucanases are pH 5.0-5.5 and 6.0 for Acremonium EG_40_like/Cel45B and Thermoascus EG_28/Cel5A, respectively. The optimal temperature for enzymatic activity of these endoglucanases was determined at the temperature range of 50-85.degree. C. as described above. The highest activity of the enzymes was determined to be at 75.degree. C., 60.degree. C., and 75.degree. C. for the Acremonium EG_40/Cel45A, EG_40_like/Cel45B, and Thermoascus EG_28/Cel5A, respectively (FIG. 6B).

[0213] The chosen transformants were cultivated, as described in Example 14, in a 2 litre bioreactor for four days (28.degree. C., pH 4.2) to obtain material for the application tests.

Example 20

Cloning of Acremonium thermophilum ALKO4245, Chaetomium thermophilum ALKO4261, and Thermoascus aurantiacus ALKO4242 Beta-Glucosidase Genes

[0214] Standard molecular biology methods were used as described in Example 13. The construction of the Acremonium, Chaetomium, and Thermoascus genomic libraries has been described in Example 12.

[0215] The peptides derived from the purified Acremonium, Chaetomium, and Thermoascus .beta.-glucosidases shared homology with several .beta.-glucosidases of glycosyl hydrolase family 3 such as Acremonium cellulolyticus (BD168028), Trichoderma viride (AY368687), and Talaromyces emersonii (AY072918) .beta.-glucosidases, respectively. To amplify a probe for screening of the Acremonium, Chaetomium, or Thermoascus genomic libraries, degenerate primers were designed on the basis of the peptide sequences. The order of the peptides in the protein sequence and the corresponding sense or anti-sense nature of the primers was deduced from the comparison with the homologous published .beta.-glucosidases. Primer sequences and the corresponding peptides are listed in Table 20.

[0216] The probes for screening genomic libraries constructed were amplified with the listed primer combinations (Table 20) using Acremonium, Chaetomium, or Thermoascus genomic DNA as template. The PCR reaction mixtures contained 50 mM Tris-HCl, pH 9.0, 15 mM (NH.sub.4).sub.2SO.sub.4, 0.1% Triton X-100, 1.5 mM MgCl.sub.2, 0.1-0.2 mM dNTPs, 0.25 .mu.g each primer, 1 unit of Dynazyme EXT DNA polymerase (Finnzymes, Finland) and approximately 0.5 .mu.g of genomic DNA. The conditions for PCR reactions were the following: 5 min initial denaturation at 95.degree. C., followed by 30 cycles of 1 min at 95.degree. C., 1 min annealing at 40.degree. C. (Acremonium DNA as a template), at 50.degree. C. (Chaetomium DNA as a template), or at 63.degree. C. (Thermoascus DNA as a template), 2-3 min extension at 72.degree. C. and a final extension at 72.degree. C. for 5-10 min.

[0217] Specific PCR products of expected size (estimated from the homologous .beta.-glucosidase sequences BD168028, AY072918, and AY368687) were isolated from the agarose gel. DNA fragments of about 1.8 kb (Acremonium), 1.5 kb (Chaetomium), and 1.52 kb (Thermoascus) were cloned into the pCR4-TOPO.RTM. TA vector (Invitrogen, USA) resulting in plasmids pALK1924, pALK1935, and pALK1713, respectively. The DNA products were characterized by sequencing and by performing Southern blot hybridizations to the genomic DNA digested with several restriction enzymes. The hybridization patterns in stringent washing conditions suggest that one putative .beta.-glucosidase gene could be isolated from the Acremonium, Chaetomium, and Thermoascus genomic library. The deduced amino acid sequences of all three PCR products have homology to several published .beta.-glucosidase sequences of glycosyl hydrolase family 3 (BLAST program, National Center for Biotechnology Information; Altschul et al., 1990).

[0218] The insert from plasmids pALK1713, pALK1924, and pALK1935 was isolated by restriction enzyme digestion and labeled with digoxigenin according to the supplier's instructions (Roche, Germany). About 1-2.times.10.sup.5 plaques from the amplified Acremonium, Chaetomium, or Thermoascus genomic library were screened as described in Example 18. Several positive plaques were obtained, of which five to six strongly hybridizing plaques were purified from each screening. Phage DNAs were isolated and analysed by Southern blot hybridization. Restriction fragments hybridizing to the probe were subcloned into the pBluescript II KS+ vector (Stratagene, USA) and the relevant parts were sequenced. In all cases the subcloned phage fragment contains the full-length gene of interest. Table 21 summarises the information of the probes used for screening of the .beta.-glucosidase genes, phage clones from which the genes were isolated, chosen restriction fragments containing the full-length genes with their promoter and terminator regions, names of plasmids containing the subcloned phage fragment, and the deposit numbers in the Deutsche Sammlung von Mikroorganismen and Zellkulturen GmbH culture collection (DSM) for E. coli strains carrying these plasmids.

Production of Recombinant Beta-Glucosidases in Trichoderma reesei

[0221] Expression plasmids were constructed for production of the recombinant Acremonium .beta.G_101/Cel3A, Chaetomium PG_76/Cel3A, and Thermoascus .beta.G_81/Cel3A proteins as described in Example 14. Linear expression cassettes (Table 25) were isolated from the vector backbone by restriction enzyme digestion, transformed into T. reesei A96 or A33 (both strains have the genes encoding the four major cellulases CBHI/Cel7A, CBHII/Cel6A, EGI/Cel7B and EGII/Cel5A deleted) and transformants purified as described in Example 14.

[0222] The beta-glucosidase production of the transformants was analyzed from the culture supernatants of shake flask cultivations (50 ml). Transformants were grown as in Example 14 and the enzyme activity of the recombinant protein was measured from the culture supernatant using 4-nitrophenyl-.beta.-D-glucopyranoside substrate as described by Bailey and Nevalainen 1981. Production of the recombinant proteins was also detected from culture supernatants by SDS-polyacrylamide gel electrophoresis. In addition, the expression of Thermoascus .beta.G_81 was verified by Western blot analysis with anti-.beta.G_81 antibodies as described in Example 19. The genotypes of the chosen transformants were analysed by Southern blotting using the expression cassette as a probe.

[0223] The pH optimum of the heterologously produced .beta.-glucosidases was determined in the universal McIlvaine's buffer within a pH range of 3.0-8.0 using 4-nitrophenyl-.beta.-D-glucopyranoside as substrate. The pH optima for the Acremonium .beta.G_101, Chaetomium .beta.G_76, and Thermoascus .beta.G_81 are pH 4.5, 5.5, and 4.5, respectively (FIG. 7A). The optimal temperature for enzymatic activity of these .beta.-glucosidases was determined at the temperature range of 50-85.degree. C. as described above. The highest activity of the enzymes was determined to be at 70.degree. C., 65.degree. C., and 75.degree. C. for the Acremonium .beta.G_101/Cel3A, Chaetomium .beta.G_76/Cel3A, and Thermoascus .beta.G_81/Cel3A, respectively (FIG. 7B).

[0224] The chosen transformants were cultivated, as described in Example 14, in a 2 litre bioreactor for four days (28.degree. C., pH 4.2) to obtain material for the application tests.

Example 22

Cloning of Acremonium thermophilum ALKO4245 and Thermoascus aurantiacus ALKO4242 Xylanase Genes

[0225] Standard molecular biology methods were used as described in Example 13. The construction of the Acremonium genomic library has been described in Example 12.

[0226] The peptides derived from the purified Acremonium xylanase shared homology with xylanases of the glycosyl hydrolase family 10 such as Humicola grisea XYNI (AB001030). All peptides derived from the Thermoascus xylanase were completely identical with the published Thermoascus aurantiacus XYNA sequence (AJ132635) thus identifying the purified protein as the same enzyme. Due to this the Thermoascus xylanase gene was amplified by PCR from the genomic DNA.

[0227] To amplify a probe for screening of the Acremonium xylanase gene from the genomic library, degenerate primers were designed on the basis of the peptide sequences (Example 11, Table 5). The order of the peptides in the protein sequence and the corresponding sense or antisense nature of the primers was deduced from the comparison with the homologous Humicola insolens XYNI sequence (AB001030). The sense primer sequence (GAYGGYGAYGCSACYTAYATG) is based on Peptide 3 (amino acids 2-8) and anti-sense primer (YTTYTGRTCRTAYTCSAGRTTRTA) on Peptide 1 (amino acids 4-11).

[0228] A PCR product of expected size (estimated from the homologous Humicola insolens XYNI sequence AB001030) was obtained from the reaction. This DNA fragment of about 0.7 kb was cloned into the pCR4-TOPO.RTM. TA vector (Invitrogen, USA) resulting in plasmid pALK1714, and was characterized by sequencing. The deduced amino acid sequence of the PCR product has homology to several published xylanase sequences of glycosyl hydrolase family 10 (BLAST program, National Center for Biotechnology Information; Altschul et al., 1990).

[0229] The insert from plasmid pALK1714 was isolated by restriction enzyme digestion and labeled with digoxigenin according to the supplier's instructions (Roche, Germany). About 1-2.times.10.sup.5 plaques from the amplified Acremonium genomic library were screened as described in Example 18. Several positive plaques were obtained, of which five strongly hybridizing plaques were purified. Phage DNAs were isolated and analysed by Southern blot hybridization. A 3.0 kb XbaI restriction fragment hybridizing to the probe was subcloned into the pBluescript II KS+ vector (Stratagene, USA) resulting in plasmid pALK1725. Relevant parts of pALK1725 were sequenced and found to contain the full-length Acremonium thermophilum xyn10A gene (SEQ ID NO: 19). The deposit number of the E. coli strain containing pALK1725 in the Deutsche Sammlung von Mikroorganismen und Zellkulturen GmbH culture collection is DSM 16726.

[0230] Thermoascus aurantiacus xyn10A gene (SEQ ID NO: 17) was amplified directly from the isolated genomic DNA by PCR reaction. The forward (TTATACCGCGGGAAGCCATGGTTCGACCAACGATCCTAC) and reverse (TTATAGGATCCACCGGTCTATACTCACTGCTGCAGGTCCTG) primers that were used in the amplification of the gene were designed on the basis of the published T. aurantiacus xynA gene (AJ132635). The PCR reaction mixtures contained 50 mM Tris-HCl, pH 9.0, 15 mM (NH.sub.4).sub.2SO.sub.4, 0.1% Triton X-100, 1.5 mM MgCl2, 0.3 mM dNTPs, 1 .mu.M each primer, 1 unit of Dynazyme EXT DNA polymerase (Finnzymes, Finland) and approximately 0.5 .mu.g of Thermoascus genomic DNA. The conditions for PCR reactions were the following: 5 min initial denaturation at 95.degree. C., followed by 30 cycles of 1 min at 95.degree. C., 1 min annealing at 60-66.degree. C., 3 min extension at 72.degree. C. and a final extension at 72.degree. C. for 10 min. The amplified 1.9 kb product containing the exact gene (from START to STOP codon) was cloned as a SacII-BamHI fragment into the pBluescript II KS+ vector. Three independent clones were sequenced and one clone was selected and designated as pALK1715. The deposit number of the E. coli strain containing pALK1715 in the Deutsche Sammlung von Mikroorganismen und Zellkulturen GmbH culture collection is DSM 16724.

[0231] Relevant information of the genes and deduced protein sequences (SEQ ID NO: 17-20) are summarized in Table 26 and Table 27, respectively. Peptide sequences of the purified Acremonium XYN_60 and Thermoascus XYN_30 proteins were found in the corresponding deduced amino acid sequences of the cloned genes (At xyn10A and Ta xyn10A, respectively) confirming that appropriate genes were cloned.

[0232] The deduced protein sequences of Acremonium and Thermoascus xylanases share homology with several enzymes of glycosyl hydrolase family 10, identifying the corresponding genes as members of family 10 xylanases. The closest counterpart for the Acremonium XYN_60/Xyn10A found is the Humicola grisea XYLI (AB001030) showing 67.1% identity with XYN_60 (Table 28). The predicted protein sequence of the isolated Thermoascus aurantiacus XYN_30/Xyn10A xylanase is completely identical with that of the published T. aurantiacus XYNA (P23360, Table 28). The closest homology was found in a xylanase sequence of Aspergillus niger (A62445, 69.7% identity).

Production of Recombinant Xylanases in Trichoderma reesei

[0233] Expression plasmids were constructed for production of the recombinant Acremonium XYN_60/Xyn10A and Thermoascus XYN_30/Xyn10A proteins as described in Example 14. Linear expression cassettes (Table 29) were isolated from the vector backbone by restriction enzyme digestion, transformed into T. reesei A96, and transformants purified as described in Example 14.

[0234] The xylanase production of the transformants was analyzed from the culture supernatants of shake flask cultivations (50 ml). Transformants were grown as in Example 14 and the enzyme activity of the recombinant protein was measured from the culture supernatant as the release of reducing sugars from birch xylan (1% w/v) at 50.degree. C. in 50 mM citrate buffer pH 5.3 as described by Bailey and Poutanen 1989. Production of the recombinant protein was also analyzed from culture supernatant by SDS-polyacrylamide gel electrophoresis. In addition, the expression of both xylanases was determined by Western blot analysis with anti-XYN_30 or anti-XYN_60 antibodies as described in Example 19. The genotypes of the chosen transformants were analysed by Southern blotting using the expression cassette as a probe.

[0235] Thermoascus XYN_30/Xyn10A was produced in T. reesei and the pH optimum of the heterologously produced protein was determined in the universal McIlvaine's buffer within a pH range of 3.0-8.0 using birch xylan as substrate (FIG. 8A). The optimal pH was determined to be 4.5. The temperature optimum for the enzymatic activity of XYN_30 was determined to be 75.degree. C. (FIG. 8B).

[0236] The chosen transformants were cultivated, as described in Example 14, in a 2 litre bioreactor for four days (28.degree. C., pH 4.2) to obtain material for the application tests.

Example 24

Performance of the Recombinant Cellobiohydrolases in the Hydrolysis

[0237] The performance of the purified recombinant cellobiohydrolases was evaluated in the hydrolysis studies with purified T. reesei enzymes. Hydrolysis was carried out with controlled mixtures of purified enzymes on several pre-treated substrates. Culture filtrates of T. reesei, containing different cloned CBH/Cel7 enzymes were obtained as described in Examples 14 and 15, and the CBH enzymes were purified by affinity chromatography as described in Example 2. In addition, pure T. reesei cellulases (purified as described by Suurnakki et al., 2000) were used in the enzyme mixtures. The cellobiohydrolases used in the experiment were:

[0238] Thermoascus aurantiacus ALKO4242 CBH (Ta Cel7A)

[0239] Thermoascus aurantiacus ALKO4242 CBH (Ta Cel7A) with genetically attached CBD of Trichoderma reesei (Ta Cel7A+Tr CBD)

[0240] Thermoascus aurantiacus ALKO4242 CBH (Ta Cel7A) with genetically attached CBD of Chaetomium thermophilum (Ta Cel7A+Ct CBD)

[0241] Acremonium thermophilum ALKO4245 CBH (At Cel7A)

[0242] Chaetomium thermophilum ALKO4265 CBH (Ct Cel7A).

[0243] Each CBH/Cel7 to be tested (dosage 14.5 mg/g dry matter of substrate) was used either together with EGII/Cel5A of T. reesei (3.6 mg/g) or with a mixture containing T. reesei EGI/Cel7B (1.8 mg/g), EGII/Cel5A (1.8 mg/g), xylanase pI 9 (Tenkanen et al. 1992) (5000 nkat/g) and acetyl xylan esterase (AXE) (Sundberg and Poutanen, 1991) (250 nkat/g). All mixtures were supplemented with additional .beta.-glucosidase from a commercial enzyme preparation Novozym 188 (176 nkat/g d.w.). Triplicate tubes containing the enzyme mixture and 10 mg (dry matter)/ml of the substrate suspended in 0.05 M sodium acetate were incubated in mixing by magnetic stirring at 45.degree. C. for 48 h. Reference samples with inactivated enzymes and corresponding substrates were also prepared. The release of hydrolysis products was measured as reducing sugars with DNS method using glucose as standard (Table 30).

[0244] The following substrates were used in the experiment:

[0245] Crystalline cellulose (Avicel)

[0246] Washed steam pre-treated spruce fibre (impregnation with 3% w/w SO.sub.2 for 20 min, followed by steam pre-treatment at 215.degree. C. for 5 min), dry matter 25.9% (SPRUCE).

[0249] In Table 30 the different cellobiohydrolases have been compared based on the same protein dosage in the hydrolysis. The results show that on cellulosic substrates (Avicel and spruce fibre) Cel7A of Thermoascus aurantiacus with genetically attached CBD showed clearly higher hydrolysis than T. reesei CBHI/Cel7A. Without CBD, T. aurantiacus Cel7A was less efficient on these substrates. The performance of Acremonium thermophilum and Chaetomium thermophilum cellobiohydrolases was also better than that of T. reesei CBHI/Cel7A on several substrates; in particular, C. thermophilum Cel7A showed high efficiency on pure cellulose (Avicel).

[0250] In the case of substrates containing notable amounts of hemicellulose (willow and corn stover) the CBH/Cel7 enzymes clearly needed additionally both hemicellulases and endoglucanases to perform efficiently. If no additional hemicellulases were present, Cel7A of T. aurantiacus with genetically attached CBD showed again clearly highest hydrolysis. With the most important hemicellulose-degrading enzymes (xylanase, acetyl xylan esterase and EGI) Cel7A of T. aurantiacus with genetically attached CBD performed again with highest efficiency. A. thermophilum Cel7A was more efficient than T. reesei enzyme and C. thermophilum Cel7A produced hydrolysis products on the same level than T. reesei CBHI/Cel7A. The cellulose binding domain of T. reesei seemed to give slightly better efficiency than CBD of C. thermophilum in the hydrolytic performance of T. aurantiacus Cel7A, even though the difference was rather small.

[0251] It can be concluded that when CBHI/Cel7A was replaced in the mixture of Trichoderma enzymes by the herein produced cellobiohydrolases, the hydrolysis efficiency as judged by this experimental arrangements was clearly improved in the case of T. aurantiacus Cel7A with genetically attached CBD, and also improved in the case of A. thermophilum Cel7A and C. thermophilum Cel7A. Considering also the better temperature stability of the herein produced cellobiohydrolases, the results indicate that the performance of cellulase enzyme mixtures in higher temperatures than 45.degree. C. can be clearly improved by using the herein produced cellobiohydrolases.

Example 25

Performance of the Recombinant Endoglucanases in the Hydrolysis

[0252] The preparations containing the endoglucanases were compared in hydrolysis studies mixed with the purified CBH/Cel7 and CBH/Cel6 enzymes on several pre-treated substrates. Culture filtrates of T. reesei, containing different cloned endoglucanase enzymes were obtained as described in Example 19. The enzymes were enriched by removing thermolabile proteins from the mixtures by a heat treatment (60.degree. C., 2 h, pH 5) and the supernatant was used for the hydrolysis studies. In addition, pure T. reesei cellulases (purified as described by Suurnakki et al., 2000) were used in the enzyme mixtures. The endoglucanases used in the experiment were:

[0253] Acremonium thermophilum ALKO4245 endoglucanase At EG_40/Cel45A (ALKO4245 EG_40)

[0254] Acremonium thermophilum ALKO4245 endoglucanase At EG_40_like/Cel45B (ALKO4245 EG_40_like)

[0255] Thermoascus aurantiacus ALKO4242 endoglucanase Ta EG_28/Cel5A (ALKO4242 EG_28).

[0256] The following substrates were used in the experiment:

[0257] Washed steam pre-treated spruce fibre (impregnation with 3% SO.sub.2 for 20 min, followed by steam pre-treatment at 215.degree. C. for 5 min), dry matter 25.9% (SPRUCE).

[0258] Steam exploded corn stover fibre (steam pre-treatment at 210.degree. C. for 5 min), dry matter 31.0% (SECS).

[0259] The endoglucanases to be studied (dosage 840 nkat/g dry matter, based on endoglucanase activity against HEC according to IUPAC, 1987) were used either with cellobiohydrolases of T. reesei (CBHI/Cel7A, 8.1 mg/g d.m. and CBHII/Cel6A, 2.0 mg/g d.m.) or with Thermoascus aurantiacus Cel7A with genetically attached CBD of T. reesei (10.1 mg/g d.m.). Purified (Suurnakki et al., 2000) EGI (Cel7B) and EGII (Cel5A) of T. reesei were also included in the experiments for comparison. All mixtures were supplemented with additional .beta.-glucosidase from Novozym 188 (to make the total .beta.-glucosidase dosage 560 nkat/g d.w., the relatively high dosage was used to compensate the differences in the background activities of the different EG preparations). Triplicate tubes were incubated in mixing at 45.degree. C. for 48 h and reference samples with inactivated enzymes and corresponding substrates were prepared. The release of hydrolysis products was measured as reducing sugars with DNS method using glucose as standard (Table 31).

[0260] In Table 31 the different endoglucanases have been compared based on the same activity dosage in the hydrolysis. This may favour enzymes with low specific activity against the substrate (hydroxyethyl cellulose) used in the assay and underestimate the efficiency of enzymes with high specific activity against hydroxyethyl cellulose. In any case, the results show that Acremonium thermophilum endoglucanases perform very well in the hydrolysis when affecting together with both cellobiohydrolases used in the mixture. A. thermophilum endoglucanases have similar performance to T. reesei EGI/Cel7B which is a very efficient enzyme on hemicellulose-containing corn stover substrate due to its strong xylanase side activity. T. aurantiacus endoglucanase Cel5A (ALKO4242 EG_28) showed lower hydrolysis than T. reesei enzymes.

[0261] It can be concluded that the endoglucanases from A. thermophilum perform with comparable or enhanced efficiency when compared to the corresponding Trichoderma enzymes in the hydrolysis as judged by this experimental arrangement. Considering also the temperature stability of the herein described endoglucanases, the results indicate that the performance of cellulase enzyme mixtures in higher temperatures than 45.degree. C. can be improved by using the herein described endoglucanases.

Example 26

Hydrolysis of Steam Pre-Treated Spruce at High Temperatures

[0262] Washed steam exploded spruce fibre (impregnation with 3% w/w SO.sub.2 for 20 min, followed by steam pre-treatment at 215.degree. C. for 5 min), with dry matter of 25.9% was suspended in 5 ml of 0.05 M sodium acetate buffer in the consistency of 10 mg/ml. This substrate was hydrolysed using different enzyme mixtures in test tubes with magnetic stirring in the water bath adjusted in different temperatures for 72 h. For each sample point, a triplicate of test tubes was withdrawn from hydrolysis, boiled for 10 min in order to terminate the enzyme hydrolysis, centrifuged, and the supernatant was analysed for reaction products from hydrolysis. The blanks containing the substrate alone (only buffer added instead of enzymes) were also incubated in the corresponding conditions.

[0263] A mixture of thermophilic cellulases was prepared using the following components:

[0264] Thermophilic CBH/Cel7 preparation containing Thermoascus aurantiacus ALKO4242 Cel7A with genetically attached CBD of T. reesei CBHI/Cel7A. The protein preparation was produced as described in Example 15 and purified according to Example 2 resulting in the purified Ta Cel7A+Tr CBD preparation with protein content of 5.6 mg/ml.

[0265] Thermophilic endoglucanase preparation containing Acremonium thermophilum ALKO4245 endoglucanase At EG_40/Cel45A. The protein was produced in T. reesei as described in Example 19. In order to enrich the thermophilic components, the spent culture medium was heat treated (60.degree. C. for 2 hours). The preparation obtained contained protein 4.9 mg/ml and endoglucanase activity (according to IUPAC, 1987) 422 nkat/ml.

[0266] Thermophilic .beta.-glucosidase preparation prepared as described in Example 21 containing Thermoascus aurantiacus ALKO4242 .beta.-glucosidase Ta .beta.G_81/Cel3A. In order to enrich the thermophilic components, the fermentor broth was heat treated (65.degree. C. for 2 hours). The preparation obtained contained 4.3 mg/ml protein and .beta.-glucosidase activity of 6270 nkat/ml (according to Bailey and Linko, 1990).

[0267] These enzyme preparations were combined as follows (per 10 ml of mixture): CBH/Cel7-preparation 4.51 ml, endoglucanase preparation 5.19 ml and .beta.-glucosidase preparation 0.29 ml. This mixture was used as "MIXTURE 1" of the thermophilic enzymes.

[0268] As a comparison and reference, a state-of art mixture of commercial Trichoderma reesei enzymes was constructed combining (per 10 ml): 8.05 ml Celluclast 1.5 L FG (from Novozymes A/S) and 1.95 ml Novozym 188 (from Novozymes A/S). This was designated as "T. REESEI ENZYMES."

[0269] Enzymes were dosed on the basis of the FPU activity of the mixtures: "MIXTURE 1" using the dosage of 5.5 FPU per 1 gram of dry matter in the spruce substrate, and "T. REESEI ENZYMES" using 5.8 FPU per 1 gram of dry matter in the spruce substrate.

[0270] Samples were taken from the hydrolysis after 24, 48 and 72 h and treated as described above. The hydrolysis products were quantified using the assay for reducing sugars (Bernfeld, 1955), using glucose as standard. The amount of hydrolysis products as reducing sugars is presented in FIG. 9.

[0271] The results clearly show better performance of the herein described enzymes as compared to the state-of-art Trichoderma enzymes in 55.degree. C. and 60.degree. C. on the spruce substrate. On the basis of HPLC analysis the maximum yield of sugars from the substrate would be 5.67 mg per 10 mg of dry spruce substrate. Because of the relatively low dosage of enzyme the final sugar yields were clearly lower. For thermostable enzymes the sugar yield based on reducing sugar assay was 66% and 57% of theoretical in 55.degree. C. and 60.degree. C., respectively. For state-of art Trichoderma enzymes it was only 31% and 11% in 55.degree. C. and 60.degree. C., respectively.

Example 27

Hydrolysis of Steam Pre-Treated Corn Stover at High Temperatures

[0272] Steam exploded corn stover fibre (treatment at 195.degree. C. for 5 min), with dry matter of 45.3% was suspended in 5 ml of 0.05 M sodium acetate buffer in the consistency of 10 mg/ml. The treatments and measurements were performed as described in Example 26.

[0273] A mixture of herein described thermophilic cellulases was constructed using the following components:

[0274] Thermophilic CBH preparation containing Thermoascus aurantiacus ALKO4242 Cel7A with genetically attached CBD of T. reesei CBHI/Cel7A (Ta Cel7A+Tr CBD, Example 15). The protein content of the preparation was 31 mg/ml.

[0275] Thermophilic endoglucanase preparation containing Acremonium thermophilum ALKO4245 endoglucanase At EG_40/Cel45A was obtained as described in Example 19. The concentrated enzyme preparation contained endoglucanase activity (according to IUPAC, 1987) of 2057 nkat/ml.

[0276] Thermophilic .beta.-glucosidase preparation containing Thermoascus aurantiacus ALKO 4242 .beta.-glucosidase Ta PG_81/Cel3A was obtained as described in Example 21 containing .beta.-glucosidase activity (according to Bailey and Linko, 1990) of 11500 nkat/ml.

[0277] Thermophilic xylanase product containing an AM24 xylanase originating from Nonomuraea flexuosa DSM43186. The product was prepared by using a recombinant Trichoderma reesei strain that had been transformed with the expression cassette pALK1502, as described in WO2005/100557. The solid product was dissolved in water to make a 10% solution and an enzyme preparation with xylanase activity (assayed according to Bailey et al., 1992) of 208000 nkat/ml was obtained.

[0278] These enzyme preparations were combined as follows (per 10 ml of mixture): CBH/Cel7 preparation 7.79 ml, endoglucanase preparation 0.96 ml, .beta.-glucosidase preparation 1.14 ml and xylanase preparation 0.31 ml. This mixture was used as "MIXTURE 2" of the thermophilic enzymes.

[0279] As a comparison and reference, a state-of art mixture of commercial Trichoderma reesei enzymes was constructed by combining (per 10 ml) 8.05 ml Celluclast 1.5 L FG (from Novozymes A/S) and 1.95 ml Novozym 188 (from Novozymes A/S). This was designated as "T. REESEI ENZYMES."

[0280] Samples were taken from the hydrolysis after 24, 48 and 72 h and treated as described above. The hydrolysis products were quantified using the assay for reducing sugars (Bernfeld, 1955), using glucose as standard. The results from the substrate blanks were subtracted from the samples with enzymes, and the concentration of hydrolysis products as reducing sugars is presented in FIG. 10.

[0281] The results clearly show better performance of the herein described enzymes as compared to the state-of-art Trichoderma enzymes. In 45.degree. C. the mixture of thermophilic enzymes showed more efficient hydrolysis as compared to T. reesei enzymes: The hydrolysis was faster and higher sugar yields were also obtained. On the basis of HPLC analysis the maximum yield of sugars (including free soluble sugars in the unwashed substrate that was used) from the substrate would be 5.73 mg per 10 mg of dry substrate. Thus, the hydrolysis by the MIXTURE 2 enzymes was nearly complete within 48 hours. In 55.degree. C. and 57.5.degree. C. the herein described thermophilic enzymes showed also clearly better performance in the hydrolysis as compared to the state-of art Trichoderma enzymes.

Example 28

Hydrolysis of Pre-Treated Corn Stover at High Temperatures Using Mixture with a Thermostable Xylanase

[0282] The procedure explained in Example 27 was repeated except that the xylanase product XT 02026A3 was replaced by thermophilic xylanase preparation containing Thermoascus aurantiacus ALKO4242 xylanase Ta XYN_30/Xyn10A produced in T. reesei. The fermentor broth, produced as described in Example 23 contained xylanase activity of 132 000 nkat/ml (assayed according to Bailey et al., 1992).

[0283] These enzyme preparations were combined as follows (per 10 ml of mixture): CBH/Cel7-preparation 7.64 ml, endoglucanase preparation 0.96 ml, .beta.-glucosidase preparation 1.15 ml and xylanase preparation 0.25 ml. This mixture was used as "MIXTURE 3" of the thermophilic enzymes.

[0284] As a comparison and reference, a state-of-art mixture of commercial Trichoderma reesei enzymes was constructed by combining (per 10 ml) 8.05 ml Celluclast 1.5 L FG (from Novozymes A/S) and 1.95 ml Novozym 188 (from Novozymes A/S). This was designated as "T. REESEI ENZYMES."

[0285] Samples were taken from the hydrolysis after 24, 48 and 72 h and treated as described above. The hydrolysis products were quantified using the assay for reducing sugars (Bernfeld, 1955), using glucose as standard. The results from the substrate blanks were subtracted from the samples with enzymes, and the concentration of hydrolysis products as reducing sugars is presented in FIG. 11.

[0286] The results clearly show better performance of the mixture of the herein described enzymes as compared to the state-of-art Trichoderma enzymes. In 45.degree. C. the mixture of thermophilic enzymes showed more efficient hydrolysis as compared to T. reesei enzymes. In 55.degree. C. and 60.degree. C. the herein described thermophilic enzymes showed clearly better performance in the hydrolysis as compared to the state-of art Trichoderma enzymes. The performance of the new enzyme mixture at 60.degree. C. was at the same level than the performance of state-of-art enzymes at 45.degree. C.

Example 29

Hydrolysis of Pre-Treated Spruce at High Temperatures Using Mixture with a Thermostable Xylanase

[0287] Procedure as described in Example 28 was repeated with washed steam exploded spruce fibre (impregnation with 3% w/w SO.sub.2 for 20 min, followed by steam pre-treatment at 215.degree. C. for 5 min, with dry matter of 25.9%) as substrate using hydrolysis temperatures 45.degree. C., 55.degree. C. and 60.degree. C. Samples were taken from the hydrolysis after 24, 48 and 72 h and treated as described above. The hydrolysis products were quantified using the assay for reducing sugars (Bernfeld, 1955), using glucose as standard. The results from the substrate blanks were subtracted from the samples with enzymes, and the concentration of hydrolysis products as reducing sugars is presented in FIG. 12.

[0288] The results clearly show better performance of the mixture of herein described enzymes as compared to the state-of-art Trichoderma enzymes in all the temperatures studied. At 45.degree. C. the mixture of thermophilic enzymes showed more efficient hydrolysis as compared to T. reesei enzymes, evidently due to the better stability in long term hydrolysis. At 55.degree. C. the efficiency of the mixture of herein described enzymes was still on the same level than at 45.degree. C., whereas the state-of-art mixture was inefficient with the substrate used in this temperature. At 60.degree. C. the herein described thermophilic enzymes showed decreased hydrolysis although the hydrolysis was nearly at the same level as the performance of the state-of-art enzymes at 45.degree. C.

Example 30

Evaluation of Glucose Inhibition of .beta.-Glucosidases from Acremonium thermophilium ALKO4245, Chaetomium thermophilum ALKO4261 and Thermoascus aurantiacus ALKO4242

[0289] The culture filtrates produced by Acremonium thermophilium ALKO4245, Chaetomium thermophilum ALKO4261 and Thermoascus aurantiacus ALKO4242 strains are described in Example 1. The .beta.-glucosidase activities (measured according to Bailey and Linko, 1990) of these preparations were 21.4 nkat/ml, 5.6 nkat/ml and 18.6 nkat/ml, respectively. For comparison, commercial enzymes Celluclast 1.5 L (.beta.-glucosidase 534 nkat/ml) and Novozym 188 (.beta.-glucosidase 5840 nkat/ml) were also included in the experiment.

[0290] In order to evaluate the sensitivity of the different .beta.-glucosidases towards glucose inhibition, the standard activity assay procedure was performed in the presence of different concentrations of glucose. The substrate (p-nitrophenyl-.beta.-D-glucopyranoside) solutions for .beta.-glucosidase activity assay were supplemented by glucose so that the glucose concentration in the assay mixture was adjusted to the values from 0 to 0.5 M. Except this glucose addition the assay was performed using the standard procedure (Bailey and Linko, 1990). The activities in the presence of varying glucose concentrations as a percentage of the activity without glucose are presented in FIG. 13.

[0291] The results show that .beta.-glucosidases from C. thermophilum and T. aurantiacus were affected less by glucose inhibition than the .beta.-glucosidases present in the commercial enzymes: Aspergillus-derived .beta.-glucosidase in Novozym 188 or Trichoderma-derived .beta.-glucosidase in Celluclast 1.5 L. A. thermophilum enzyme showed behaviour comparable to T. reesei enzyme of Celluclast. Especially C. thermophilum enzyme was clearly less affected by high glucose concentration. Thus, these results indicate that considering glucose inhibition the use of the new .beta.-glucosidases, especially from strains Acremonium thermophilium ALKO4242 and Chaetomium thermophilum ALKO4261, would give clear advantages in hydrolysis in industrial conditions with high glucose concentration.

Example 31

Filter Paper Activity of Enzyme Mixtures in High Temperatures

[0292] Filter paper activity of enzyme preparations was measured according to the method of IUPAC (1987) as described in the procedure except enzyme reaction was performed at temperatures from 50.degree. C. to 70.degree. C. The calculated FPU activity is based on the amount of enzyme required to hydrolyse 4% of filter paper substrate in 1 h under the experimental conditions. The FPU activity is considered to represent the total overall cellulase activity of an enzyme preparation.

[0293] The enzyme mixtures were MIXTURE 2 prepared as described in Example 27, MIXTURE 3 prepared as described in Example 28, and MIXTURE 4. MIXTURE 4 was prepared by combining enzyme preparations described in Example 27 as follows (per 10 ml of mixture): CBH/Cel7-preparation 7.84 ml, endoglucanase preparation 0.99 ml and .beta.-glucosidase preparation 1.17 ml.

[0294] The enzyme mixtures used as reference, representing the state-of art-mixtures, were:

[0295] "T. REESEI ENZYMES A" prepared as preparation "T. REESEI ENZYMES" described in Example 26.

[0296] "T. REESEI ENZYMES B" was constructed combining (per 10 ml) 8.05 ml Econase CE (a commercial T. reesei cellulase preparation from AB Enzymes Oy, Rajamaki, Finland) and 1.95 ml Novozym 188 (from Novozymes A/S).

[0297] The FPU activities measured for the enzyme preparations at different temperatures are presented in FIG. 14 as percentages of the activity under standard (IUPAC, 1987) conditions (at 50.degree. C.).

[0298] Results clearly show that the mixtures of the invention show higher overall cellulase activity in elevated (60-70.degree.) temperatures as compared to the state-of art mixtures based on enzymes from Trichoderma and Aspergillus.

Example 32

Use of the Novel Beta-Glucosidases in Preparation of Sophorose

[0299] A high concentration starch hydrolysate mixture (Nutriose 74/968, Roquette) was treated with Thermoascus aurantiacus .beta.G_81/Cel3A enriched enzyme preparation produced as described in Example 21 to produce a sugar mixture containing appreciable amounts of cellulase inducer (sophorose) to overcome the glucose repression.

[0300] The Ta .beta.G_81/Cel3A enriched enzyme preparation was added to a 70% (w/w) Nutriose solution to a final concentration of 1 g total protein/litre. The container of the mixture was incubated in a water bath at 65.degree. C. for 3 days with constant stirring and used as a carbon source in a shake flask medium for two different Trichoderma-strains (A47 and Rut-C30). The effect of the enzyme treatment was measured as an endoglucanase activity formed during a 7 days shake flask cultivation. As a reference cultivations were performed under the same conditions with untreated Nutriose as a carbon source. More than two-fold increase in the activities was obtained in the shake flask cultivations performed on Ta .beta.G_81/Cel3A pretreated Nutriose media with the strains tested. Results are shown in FIG. 15.
