Abstract
The present invention relates to a composite yeast for high concentration alcohol fermentation, which includes thermostable Saccharomyces cerevisiae, acid protease, phytase, cellulose, β-glucanase, and pectinase, and is suitable for the high concentration alcohol fermentation for various raw materials. In addition to normal fermentation, the composite yeast of the present invention can degrade the raw materials, increase the nutrient ingredients in the mash, promote the growth of yeast and provide stress tolerance protection.
