Abstract
Provided are a fungus-sourced high-temperature acid β-glucosidase as well as a coding gene, and an application thereof. The provide β-glucosidase has the optimal pH value of 4.5 and the optimal temperature of 75° C., and maintains over 90% enzyme activity in the optimal condition after being processed at 60° C. for 1 h. The re-engineering yeast strain GS115/bgl3A of the coding gene comprising the β-glucosidase has high fermentation level.
