Application of high glucose-tolerant yeast to alcohol production by sweet sorghum stalk juice fermentation

Alcohol with sweet sorghum stalk juice as raw material was fermented by angel high-temperature dry-alcohol yeast in this paper. The optimum conditions of alcohol fermentation were determined by orthogonal test and the experimental index was as follow: (NH4)2HPO4 0.20% , MgSO4 0.10% , CaCl2 0.10% . The sweet sorghum stalk juice was adjusted 28.0 g·100 mL-1, and under the suitable condition, fermentation rate was 93.0%, alcohol degree was 14.1%(v/v).
