Yeast strain for sake brewing producing high yield of β-phenethyl alcohol and use thereof

摘要

The present invention discloses a yeast strain for brewing that produces β-phenethyl alcohol in a high yield and its use, and belongs to the technical field of industrial microorganisms. The brewer's yeast strain that produces β-phenethyl alcohol of the present invention in a high yield is preserved at the Chinese Typical Culture Conservation Center on December 26, 2016, and the preservation number is CCTCC NO: M 2016785. The strain of the present invention has the ability to produce β-phenethyl alcohol in high yield, fermented with yellow liquor, cooked liquor, used in brewed vinegar, soy sauce fermentation, white sake fermentation, and the content of β-phenethyl alcohol is respectively It can reach 410 mg / L, 450 mg / L, 300 mg / L, 200 mg / L, 110 mg / L, 370 mg / L and effectively increases the concentration of the flavoring substance-2-phenylethyl acetate. The yeast strain of the present invention is excellent in fermentation performance, obviously increases the content of β-phenethyl alcohol in the product, improves the quality of the product, and thus has wide applicability.
