| 摘要 |
The invention relates to expression of a recombinant C1β-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 C1β-glucosidase, operably linked to heterologous promoter, under conditions in whichβ-glucosidase is expressed and secreted by the cell and the cellobiose is enzymatically converted by saidβ-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.
