Abstract
The present invention further discloses an application of Saccharomyces cerevisiae in the fermentation of a second generation fuel, ethanol, with a straw lignocellulose biomass hydrolysate as a raw material. Experiments prove that the strain of the prevent invention has an efficient co-fermentation capacity of C6/C5 while tolerating multiple inhibitors, and can consume all the glucose and xylose to produce ethanol; and the sugar-alcohol conversion rate is up to 0.43 g g−1. The strain and screening strategy used in the present invention provide technical reference and basis for the further breeding of a Saccharomyces cerevisiae strain which has a superior fermenting property and is produced by the second generation fuel, ethanol.
