FERMENTATION OF GLUCOSE AND XYLOSE IN CELLULOSIC BIOMASS USING GENETICALLY MODIFIED SACCHAROMYCES CEREVISIAE AND A SIMULTANEOUS SACCHARIFICATION AND CO-FERMENTATION PROCESS

摘要

The present invention relates to a method for the manufacture of ethanol by fermenting a cellulose containing biomass using a strain of Saccharomyces cerevisiae, wherein the method encompasses a) using a strain of Saccharomyces cerevisiae being capable of fermenting pentoses, including xylose, to ethanol, b) subjecting a slurry of biomass and said Saccharomyces cerevisiae strain for a simultaneous saccharification and co-fermentation of glucose and xylose, and c) isolating ethanol from the fermented slurry obtained.
