RECOMBINANT C1 B-GLUCOSIDASE FOR PRODUCTION OF SUGARS FROM CELLULOSIC BIOMASS

摘要

The invention relates to expression of a recombinant C1 ß-glucosidase. The invention also provides methods for producing a fermentable sugar from cellobiose by contacting celiobiose with a recombinant host cell comprising a polynucleotide sequence encoding C1 ß-glucosidase, operably linked to heterologous promoter, under conditions in which ß- glucosidase is expressed and secreted by the cell and the cellobiose is enzymatically converted by said ß-glucosidase to glucose. Methods of the invention may be used for conversion of a biomass substrate to a fermentable sugar, and ultimately to ethanol or other biofuel.
