Abstract:
We constructed a set of recombinant Saccharomyces cerevisiae strains with xylose-fermenting ability. A recombinant S. cerevisiae strain D-XR/ARSdR/XK, in which protein engineered NADP⁺-dependent XDH was expressed, showed 40% increased ethanol production and 23% decrease in xylitol excretion as compared with the reference strain D-XR/XDH/XK expressing the wild-type XDH.
