摘要:
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 Candida cells, methods for making the Candida cells, and their use in production of organic products, particularly lactic acid.
摘要:
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.

摘要:
Host cells, comprising Kluveryomyces expressing heterologous cellulases produce ethanol from cellulose In addition, multiple host cells expressing different heterlogous cellulases can be co-cultured together and used to produce ethanol from cellulose The recombinant yeast strains and co-cultures of the yeast strains can be used to produce ethanol on their own, or can also be used in combination with externally added cellulases to increase the efficiency of sacchanfication and fermentation processes.
