Abstract

The invention discloses a yeast strain, namely papiliotrema laurentii HSP22 and application thereof, belonging to the technical field of microorganisms. The preservation number of the yeast strain papiliotrema laurentii HSP22 is CCTCC No. M: 2021086. The yield of n-hexanol generated by fermenting grape juice by the strain reaches up to 430.37 [mu]g / L, the yield of 1-amyl alcohol reaches up to 156.79 [mu]g / L, and the yield of ethyl acetate reaches up to 160.23 [mu]g / L.

Description

technical field [0001] The invention belongs to the technical field of microbes, and in particular relates to a yeast Papiliotremalaurentii strain HSP22 and its application. Background technique [0002] There are very few yeasts (Papiliotremalaurentii) that have been reported so far. The isolated source of Papiliotremalaurentii strains available on the market is shrimp in the Gulf of Mexico. Its growth temperature is 24-26°C, and it is a typical aerobic bacteria. The yeast Papiliotremalaurentii was also identified in plateau lakes and wetlands. "The biodegradation of polyester and polyester polyurethane coatings using Papiliotremalaurentii" reported that this type of yeast can biodegrade polyester and polyurethane coatings. [0003] But about the yeast (Papiliotremalaurentii) that can produce aroma substances such as n-hexanol, 1-pentanol, and ethyl acetate, there has never been any report in this field. Contents of the invention [0004] Based on the above gaps in the ...
