Disruption of the cytochrome C gene in xylose-fermenting yeast

摘要

Disclosed is a xylose-fermenting mutant yeast strain exhibiting reduced expression of cytochrome c and enhanced fermentation of xylose relative to xylose-fermenting yeast strains in which cytochrome c is fully functional. Also disclosed is a method of producing ethanol from xylose by culturing a xylose-fermenting mutant yeast strain exhibiting reduced expression of cytochrome c in the presence of xylose-containing material.
