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.
On divulgue une souche de levure mutante de fermentation du xylose dans laquelle l'expression du cytochrome c est réduite, et dont les propriétés de fermentation du xylose sont supérieures à celles des souches de levures de fermentation du xylose dont l'expression du cytochrome c est complète. En outre, on présente une méthode de production d'éthanol à partir de xylose par culture de la souche de levure mutante de fermentation du xylose dans laquelle l'expression du cytochrome c est réduite, en présence de matières contenant du xylose.
