20150152445 | MICROORGANISMS AND METHODS FOR THE PRODUCTION OF KETONES - The invention provides a recombinant, acetogenic, carboxydotrophic bacterium that lacks secondary alcohol dehydrogenase or comprises an inactivated secondary alcohol dehydrogenase. The inactivated secondary alcohol dehydrogenase may be encoded by a secondary alcohol dehydrogenase gene comprising an inactivating mutation that reduces the ability of the bacterium to convert acetone to isopropanol and to convert methyl ethyl ketone to 2-butanol. Since a bacterium that lacks secondary alcohol dehydrogenase or comprises an inactivated secondary alcohol dehydrogenase accumulates carbonyl-containing compounds, the invention also provides a method of producing carbonyl-containing compounds, such as acetone and methyl ethyl ketone. | 06-04-2015 |
20150191747 | MICROBIAL FERMENTATION FOR THE PRODUCTION OF TERPENES - The invention provides a method for producing a terpene or a precursor thereof by microbial fermentation. Typically, the method involves culturing a recombinant bacterium in the presence of a gaseous substrate whereby the bacterium produces a terpene or a precursor thereof, such as mevalonic acid, isopentenyl pyrophosphate, dimethylallyl pyrophosphate, isoprene, geranyl pyrophosphate, farnesyl pyrophosphate, and/or farnesene. The bacterium may comprise one or more exogenous enzymes, such as enzymes in mevalonate, DXS, or terpene biosynthesis pathways. | 07-09-2015 |
20150210977 | BACTERIUM WITH INCREASED TOLERANCE TO BUTYRIC ACIDS - The invention provides a bacterium with an increased tolerance to butyric acids, such as 2-hydroxybutyric acid (2-HIBA). In particular, the invention provides a bacterium that tolerates at least 2.5 g/L of butyric acid. The bacterium may be derived, for example, from genus | 07-30-2015 |
20150210987 | RECOMBINANT MICROORGANISMS AND METHODS OF USE THEREOF - The invention provides a carboxydotrophic acetogenic bacterium comprising a disrupting mutation in a lactate biosynthesis pathway enzyme and a method of producing a product by culturing the bacterium in the presence of a substrate comprising carbon monoxide. Preferably, the lactate biosynthesis pathway enzyme is lactate dehydrogenase (LDH) or another enzyme that converts pyruvate to lactate, wherein the disrupting mutation reduces or eliminates the expression or activity of the enzyme such that the bacterium produces a reduced amount of lactate or no lactate. | 07-30-2015 |
20150211022 | METHOD OF PRODUCING A RECOMBINANT MICROORGANISM - The invention provides a genetic tool to insert, replace, delete, or otherwise manipulate a nucleic acid sequence in a microorganism to produce a recombinant microorganism. Notably, the invention makes use of homologous recombination, a type of genetic recombination in which nucleotide sequences are exchanged between two similar or identical molecules of DNA. Since the invention involves three homologous recombination events, it is referred to as a “triple cross” method. | 07-30-2015 |
20150299737 | RECOMBINANT MICROORGANISMS AND METHODS OF USE THEREOF - The invention relates to methods for the production of chemical compounds, particularly but not exclusively ethanol, by microbial fermentation. Also described are genetically modified micro-organisms capable of using carbon monoxide to produce one or more products, particularly but not exclusively ethanol as a main product, and producing a reduced amount or substantially no 2,3-butanediol and/or a precursor thereof. | 10-22-2015 |
20150353965 | CARBON CAPTURE IN FERMENTATION - The invention relates to methods of capturing carbon by microbial fermentation of a gaseous substrate comprising CO. The methods of the invention include converting CO to one or more products including alcohols and/or acids and optionally capturing CO2 to improve overall carbon capture. In certain aspects, the invention relates to processes for producing alcohols, particularly ethanol, from industrial waste streams, particularly steel mill off-gas. | 12-10-2015 |
20150376654 | RECOMBINANT MICROORGANISMS WITH INCREASED TOLERANCE TO ETHANOL - The invention relates to a recombinant carboxydotrophic acetogenic microorganism capable of producing one or more products by fermentation of a substrate comprising CO, wherein the microorganism has an increased tolerance to ethanol versus a parental carboxydotrophic acetogenic microorganism. The invention also provides, inter alia, methods for the production of ethanol and one or more other products from a substrate comprising CO using the recombinant carboxydotrophic acetogenic microorganism. | 12-31-2015 |
