20090053782 | YEAST CELLS HAVING DISRUPTED PATHWAY FROM DIHYDROXYACETONE PHOSPHATE TO GLYCEROL - Yeast cells are genetically modified to disrupt a native metabolic pathway from dihydroxyacetone to glycerol. In certain aspects, the yeast cell is of the genera | 02-26-2009 |
20090253189 | Lactic Acid-Producing Yeast Cells Having Nonfunctional L- or D-Lactate:Ferricytochrome C Oxidoreductase Cells - Yeast cells having an exogenous lactate dehydrogenase gene ae modified by reducing L- or D-lactate:ferricytochrome c oxidoreductase activity in the cell. This leads to reduced consumption of lactate by the cell and can increase overall lactate yields in a fermentation process. Cells having the reduced I, or D-lactate:ferricytochrome c oxidoreductase activity can be screened for by resistance to organic acids such as lactic or glycolic acid. | 10-08-2009 |
20100137551 | Methods and materials for the production of D-lactic acid in yeast - The present invention relates to biocatalysts that are cells, optimally of the Crabtree-negative phenotype, comprising expression vectors encoding genes heterologous to the cell that enable increased production of organic products. More specifically, the invention relates to genetically modified | 06-03-2010 |
20100144041 | L-Arabinose Fermenting Yeast - An L-arabinose utilizing yeast strain is provided for the production of ethanol by introducing and expressing bacterial araA, araB and araD genes. L-arabinose transporters are also introduced into the yeast to enhance the uptake of arabinose. The yeast carries additional genomic mutations enabling it to consume L-arabinose, even as the only carbon source, and to produce ethanol. Methods of producing ethanol include utilizing these modified yeast strains. | 06-10-2010 |
20110287505 | GENETICALLY MODIFIED YEAST SPECIES, AND FERMENTATION PROCESSES USING GENETICALLY MODIFIED YEAST - Yeast cells are transformed with an exogenous xylose isomerase gene. Additional genetic modifications enhance the ability of the transformed cells to ferment xylose to ethanol or other desired fermentation products. Those modifications include deletion of non-specific or specific aldose reductase gene(s), deletion of xylitol dehydrogenase gene(s) and/or overexpression of xylulokinase. | 11-24-2011 |
20110287506 | GENETICALLY MODIFIED YEAST SPECIES, AND FERMENTATION PROCESSES USING GENETICALLY MODIFIED YEAST - Yeastcells are transformed with an exogenous xylose isomerase gene. Additional genetic modifications enhance the ability of the transformed cells to ferment xylose to ethanol or other desired fermentation products. Those modifications include deletion of non-specific or specific aldose reductase gene(s), deletion of xylitol dehydrogenase gene(s) and/or overexpression of xylulokinase. | 11-24-2011 |
20120129230 | Genetically Modified Yeast of the Species Issatchenkia Orientalis and Closely Related Species, and Fermentation Processes Using Same - Cells of the species | 05-24-2012 |
20140038253 | COMPOSITIONS AND METHODS FOR INCREASED ETHANOL PRODUCTION FROM BIOMASS - The present application discloses the identification of the novel | 02-06-2014 |
20140080192 | Genetically Modified Yeast Species, and Fermentation Processes Using Genetically Modified Yeast - Yeast cells are transformed with an exogenous xylose isomerase gene. Additional genetic modifications enhance the ability of the transformed cells to ferment xylose to ethanol or other desired fermentation products. Those modifications include deletion of non-specific or specific aldose reductase gene(s), deletion of xylitol dehydrogenase gene(s) and/or overexpression of xylulokinase. | 03-20-2014 |
