XYLOSE FERMENTATION YEAST AND METHOD FOR PRODUCING ETHANOL BY USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a gene recombined yeast expressing xylose reductase (XR), (wild or variant) xylitol dehydrogenase (XDH) and xylulokinase (XK) and a method for efficiently producing ethanol from xylose by using the yeast. SOLUTION: Provided is a method for efficiently producing ethanol from xylose by using a gene recombined yeast containing an XR derived from Pichia stipitis and a wild or variant XDH gene introduced in a plasmid state and an XK gene derived from Saccharomyces cerevisiae introduced by chromosome insertion technique.
