RECOMBINANT YEAST CAPABLE OF PRODUCING ETHANOL FROM XYLOSE AND METHOD FOR PRODUCING ETHANOL USING SAME

摘要

The present invention relates to recombinant yeast having high productivity of ethanol from xylose and, more specifically, to recombinant yeast having a high productivity of ethanol from xylose in which a gene encoding xylose reductase (XR) derived from Spathaspora passalidarum, a gene encoding xylitol dehydrogenase (XDH), and a gene encoding xylulokinase (XK) are introduced, anda method for producing ethanol using the recombinant yeast. When ethanol is produced from cellulosic biomass full of xylose, yeast strains of the present invention are capable of producing a high yield of ethanol with little accumulation of xylitol as a by-product, and are very useful for producing biofuel using cellulosic ethanol (CE).
