20100192308 | METHOD FOR SCOURING AND BLEACHING COTTON FABRIC WITH COMPOSITE ENZYME PREPARATION IN ONE BATH - A method for scouring and bleaching cotton fabric with composite enzyme preparation in one bath is provided. The method relates to the application of composite alkaline enzyme preparation in scouring and bleaching processes of cotton fabric. The enzyme preparation for scouring and bleaching cotton fabric is compounded from cutinase, alkaline pectase, alkaline xylanase, alkaline cellulose, and carbohydrate oxidase. The method includes: scouring the cotton fabric by adding the composite enzyme preparation, glucose, oxidation bleaching stabilizer RB-3, penetrant JFC, and Triton X-100 in a treating bath at 55-70° C. and pH 8-10, and then bleaching the cotton fabric for 30 min by directly adding tetraacetyl ethylenediamine (TAED) in the scouring bath to activate hydrogen peroxide. After being treated by the method of the present invention, the cotton fabric has high impurity removal ratio, favorable wettability, and high whiteness. The present invention has the advantages of low power consumption, short process flow, and being environment friendly, and may be used to replace conventional chemical treatment process under the condition of concentrated alkali and high temperature. | 08-05-2010 |
20130065292 | Method for Increasing Microbial Catalase Production - Disclosed are methods for increasing microbial catalase production. 1-10 g/L sodium hexametaphosphate was added to the culture medium between 30-40 hours of fermentation to inhibit proteinase activity and increase the production of catalase. This simple modification of fermentation procedure can result in up to 45% increase of the production of catalase. | 03-14-2013 |

20140322788 | method for increasing protein thermal stability - The invention provides a simple and effective method for increasing thermal stability of a wide range of proteins, comprising fusing a self-assembling amphipathic peptide to the C- or N-terminal of target proteins. The fusion protein can have a half life up to 26 times longer than that of the wild type protein. | 10-30-2014 |
20150031085 | Novel Leech Hyaluronidase and Its Application - The present invention provides a novel leech HAase and a method of producing low-molecular-weight HA oligosaccharides using the leech HAase. This invention successfully cloned the first leech HAase gene and provides a method for high-level expression of the leech HAase gene. By controlling the incubation condition, different HA oligosaccharides, particularly HA4, HA6, HA8 and HA10, can be selectively generated using the leech HAase. The large-scale expression of the leech HAase and the enzymatic production of specific HA oligosaccharides are not only useful for the cosmetic, healthcare and the medical industries but also can be a great help to polysaccharides chemical synthesis and cancer research. | 01-29-2015 |
