METABOLIC ENGINEERING FOR IMPROVED XYLOSE UTILISATION OF SACCHAROMYCES CEREVISIAE

摘要

The present invention relates to a method for preparing an ethanol producing, xylose utilizing strain of Saccharomyces cerevisiae comprising genes for overexpression of xylose reductase, xylitol dehydrogenase and xylulokinase, wherein in addition to said genes, the genes for production of phosphoacetyltransferase, and acetaldehyde dehydrogenase are introduced and optionally overexpressed.
