MUTANT SACCHAROMYCES CEREVISIAE STRAIN UTILIZING XYLOSE FOR ETHANOL PRODUCTION

摘要

The present invention relates to a new xylose utilizing Saccharomyces cerevisiae strain being able to utilize xylose for ethanol production which strain is up-regulated with regard to the genes for xylose reductase (XR) and xylulose dehydrogenase (XDH) as well as xululokinase (XK) and over-expressing the non-oxidative pentose phosphate pathway (PPP) and comprising a deletion of the gene GRE3 deletion, as well as the strain has been adapted to xylose feeding.
