Abstract

The invention discloses a saccharomycopsis crataegensis strain YC30 capable of producing aroma substances at high yield and an application thereof, and belongs to the technical field of microorganisms. The preservation number of the Saccharomycopsis crataegensis strain YC30 is CCTCC (China Center for Type Culture Collection) M 2021089. The yield of n-hexanol generated by fermenting grape juice by the strain is up to 346.05 [mu] g / L, the yield of ethyl acetate is up to 245.19 [mu] g / L, and the yield of phenethyl acetate is up to 253.1 [mu] g / L.

Description

technical field [0001] The invention belongs to the technical field of microbes, and in particular relates to a strain YC30 of crotonospora spp. with high yield of aroma substances and its application. Background technique [0002] The growth condition of Saccharomycopsis crataegensis is 24-26°C and 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 very few reports on this type of yeast, and there are not many studies and applications on this type of Saccharomyces cratonia. [0003] However, Saccharomycopsis crataegensis, which can produce aroma substances such as n-hexanol, isobutyraldehyde, isovaleraldehyde, and ethyl linoleate, has never been reported in this field. Contents of the invention [0004] Based on the above-mentioned gaps in this field, the present invention screened and obtained a Saccharomycopsis crataegensis strain YC30 that fermented high-yielding aro...
