mutated xylose reductase in xylose - fermentation by s. cerevisiae.

摘要

New xylose-utilizing Saccharomyces cerevisiae mutant strain which ferments xylose to ethanol, wherein the strain expresses a K270M mutated P. stipitis XYL1 gene (1 or 2 copies of the mutated gene) together with the native P. stipitis XYL2 gene and overexpresses the endogenous XKS1 gene.
