RECOMBINANT YEAST AND METHOD FOR PRODUCING ETHANOL USING THE SAME

摘要

The invention is intended to improve xylose assimilation ability and ethanol fermentation ability in a xylose-assimilating yeast into which a xylose isomerase gene has been introduced. The amount of NADH produced by the recombinant yeast into which the xylose isomerase gene had been introduced as a result of the enzymatic reaction of acetohydroxy acid reductoisomerase is lowered.
