摘要:
The invention relates to a strain of the yeast Saccharomyces cerevisiae which, owing to deletion of the genomic sequences, no longer synthesizes hexose transporters and, as a consequence, can no longer grow on substrates with hexoses as the only carbon source, and whose ability of growing on a substrate with a hexose as the only carbon source is restored when it expresses a GLUT4 gene.

摘要:
The present invention relates to a S. cerevisiae strain expressing both arabinose and xylose utilization pathways, and in particular to a S. cerevisiae strain fermenting both arabinose and xylose to ethanol, and more particularly a S. cerevisiae strain with overexpression or upregulation of xylose- or aldose reductase (XR, AR) with xylitol dehydrogenase (XDH) together with overexpression or upregulation of genes forming an arabinose utilization pathway. The invention encompasses both laboratory and industrial strain having these properties.
摘要:
The present invention relates to a method for producing a L-arabinose utilizing yeast strain for the production of ethanol, whereby a yeast strain is modified by introducing and expressing araA gene (L-arabinose isomerase), araB gene (L-ribulokinase D121-N) and araD gene (L-ribulose-5-P 4-epimerase) and carrying additional mutations in its genome or overexpressing a TALl (transaldolase) gene, enabling it to consume L-arabinose, to use it as the only carbon source, and to produce ethanol, as well as a method for producing ethanol using such a modified strain.
