Abstract

The present invention "a strain of C. cratonensis producing aroma substances Saccharomycopsis crataegensis Strain YC30 and its application" belong to the technical field of microorganisms. Saccharomycopsis crataegensis The deposit number of strain YC30 is CCTCC NO:M 2021089. The yield of n-hexanol produced by the strain fermented grape juice was as high as 346.05 μg / L, the output of ethyl acetate was as high as 245.19 μg / L, and the output of phenethyl acetate was as high as 253.1 μg / L.

Description

technical field [0001] The invention belongs to the technical field of microorganisms, and in particular relates to a strain of Saccharomyces cratonensis producing aroma substances Saccharomycopsis crataegensis Strain YC30 and its applications. Background technique [0002] Saccharomyces cratonensis ( Saccharomycopsis crataegensis ), its growth conditions are 24-26 ℃, aerobic. This type of yeast is mainly used for scientific research, production, and production of active lipase at pH 5.5 and 7.5. At present, there are few reports on this type of yeast, and the research and application of this type of C. cratonensis are also rare. [0003] The Saccharomycopsis crataegensis, which can produce aroma substances such as n-hexanol, isobutyraldehyde, isovaleraldehyde, and ethyl linoleate, has never been reported in this field. SUMMARY OF THE INVENTION [0004] Based on the above-mentioned blanks in the art, the present invention screened and obtained a strain of C. clatonensi...
