TRAITS IN RECOMBINANT XYLOSE-GROWING SACCHAROMYCES CEREVISIAE STRAINS USING GENOME-WIDE TRANSCRIPTION ANALYSIS

摘要

New xylose-utilizing Saccharomyces cerevisiae strain which can ferment xylose to ethanol. It expresses the gene for A) xylose reductase (XR) and Xylitol dehydrogenase (XDH) or B) xylose isomerase (XI) and has a) increased transporting capacity with regard to xylose, b) increased conversion capacity of xylulose to xylulose-5P, c) increased activity of the oxidative pentose phosphate pathway, and/or d) increased activity of the non-oxidative pentose phosphate pathway.
