    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.
