Brewing yeast Musalaisi high temperature, and preparation methods of preparation Musalaisi

The present invention discloses a high-temperature fermentation Musalaisi yeast (Saccharomyces cerevisiae) CGMCCNo.7513 prepared and fermented using the strain obtained Musalaisi. By the present invention, different temperatures, sugar, alcohol and low-nitrogen tolerance analysis, measured from onset, producing liquor, flocculation, autolytic, H2S production ability, detecting the amine generating characteristic was measured pectinase activity and β - glucosidase activity assay, screened by Saccharomyces cerevisiae Musalaisi a high temperature properties, is widely used in light industry, and other fields.
