  • Hexose-pentose cofermenting yeast having excellent xylose fermentability and method for highly efficiently producing ethanol using the same
    Patent number: 8445243
    Abstract: Genetic recombinant yeast expressing xylose reductase (XR), (wild-type or mutant) xylitol dehydrogenase (XDH), and xylulokinase (XK) and a method for highly efficiently producing ethanol from xylose using the yeast are provided. Pichia stipitis-derived XR and (wild-type or modified-type) XDH genes and Saccharomyces cerevisiae-derived XK gene were introduced via chromosomal integration. Thus, a genetic recombinant yeast having a high xylose fermentation rate, being capable of producing ethanol from xylose in high yields, and having high xylose fermentability in the presence of glucose, as well as a method using the recombinant yeast for highly efficiently producing ethanol from xylose or a saccharified solution from lignocellulose-based biomass are provided. Furthermore, a method for improving the xylose fermentability of the genetic recombinant yeast of the present invention via acclimatization treatment is also provided herein.
