Title
Simultaneous saccharification and co-fermentation of glucose and xylose in steam-pretreated corn stover at high fiber content with Saccharomyces cerevisiae TMB3400
Abstract

The two main sugars in the agricultural by-product corn stover are glucose and xylose. Co-fermentation of glucose and xylose at high content of water-insoluble solids (WIS) without detoxification is a prerequisite to obtain high ethanol concentration and to reduce production costs. A recombinant strain of Saccharomyces cerevisiae, TMB3400, was used in simultaneous saccharification and fermentation (SSF) of whole pretreated slurry of corn stover at high WIS. TMB3400 co-fermented glucose and xylose with relatively high ethanol yields giving high final ethanol concentration. The ethanol productivity increased with increasing concentration of pretreatment hydrolysate in the yeast production medium and when SSF was performed in a fed-batch mode.
