1 It was also found that additional overexpression of XYL2 under the control of strong constitutive promoters in a xylose-fermenting strain not only reduced xylitol accumulation, but also increased ethanol yields. Xylitol D-xylulose reductase XYL2 Saccharomyces cerevisiae S288C
2 As the expression levels of XYL2 increased, the ethanol yields gradually improved from 0.1 to 0.3g ethanol/g xylose, while the xylitol yields significantly decreased from 0.4 to 0.1g xylitol/g xylose. Xylitol D-xylulose reductase XYL2 Saccharomyces cerevisiae S288C
