Stain Saccharomyces Cerevisiae M 2016785 Producing High Concentration of Beta-phenylethanol and Application Thereof

摘要

The present invention discloses a strain S. cerevisiae M 2016785 producing high concentration of β-phenylethanol and application thereof, and belongs to the technical field of industrial microorganisms. The strain S. cerevisiae M 2016785 producing high concentration of β-phenylethanol according to the present invention was deposited in China Center for Type Culture Collection (CCTCC) on Dec. 26, 2016 with the accession number OF CCTCC NO: M 2016785. The strain of the present invention has the high β-phenylethanol production capacity, and is applied in the fermentation of Huangjiu, the fermentation of cooking wine, the brewing of vinegar, the fermentation of soybean sauce and the fermentation of Baijiu, in which the content of β-phenylethanol can reach 410 mg/L, 450 mg/L, 300 mg/L, 200 mg/L, 110 mg/L and 370 mg/L respectively, and effectively increases the concentration of the flavor substance such as 2-phenylethyl acetate. The yeast strain of the present invention has good fermentation performance, obviously improves the β-phenylethanol content in the fermented product, and improves the quality of the fermented product, and thus has broad application prospects.
