Abstract

The invention discloses a hanseniaspora uvarum strain QTX22 capable of producing aroma substances at high yield and application thereof, and belongs to the technical field of microorganisms. The preservation number of the hanseniaspora uvarum strain QTX22 is CCTCCM 2021083. The yield of n-hexanol generated by fermenting grape juice by the strain is up to 461.27 [mu] g / L, and the yield of phenethyl acetate is up to 359.4 [mu] g / L.

Description

technical field [0001] The invention belongs to the technical field of microbes, and in particular relates to a grape juice Hansenula sporogenes strain QTX22 with high yield of aroma substances and its application. Background technique [0002] Grape juice Hanseniaspora uvarum is characterized by its oval cells with sharp ends. Colonies are not viscous and can grow anaerobically. The main uses of the common grape juice Hansenula sporogenes include: research and fermentation. E.g: [0003] Invention patent application 201910635939.8 provides a strain of Hansenula viticosa, its preservation number is CCTCCNO: M2019304, which can convert inorganic selenium into organic selenium, and the content of organic selenium is as high as 2332mg / kg. [0004] Invention patent application 201911406443.X discloses a grape juice Hanseniaspora uvarum strain A14 with the preservation number CGMCCNo.18666. This strain has a high ability to produce geraniol, and the concentration of geraniol a...
