Abstract

The invention "a grape juice Hansenula sporogenes strain QTX22 producing aroma substances and its application" belongs to the technical field of microorganisms. The one strain of grape juice Hansenula sporogenes Hanseniaspora uvarum The deposit number of strain QTX22 is CCTCC NO:M 2021083. The yield of n-hexanol produced by this strain fermented grape juice was as high as 461.27 μg / L, and the yield of phenethyl acetate was as high as 359.4 μg / L.

Description

technical field [0001] The invention belongs to the technical field of microorganisms, and in particular relates to a grape juice Hansenula sporogenes strain QTX22 that produces aroma substances and applications thereof. Background technique [0002] Hansenula spp. in grape juice ( Hanseniaspora uvarum ), its characteristic features are: the cells are oval with sharp ends. Colonies are not viscous and can grow anaerobic. The main uses of the common grape juice Hansenula spp. include: research and fermentation. E.g: [0003] Invention patent application 201910635939.8 provides a strain of Hansenula vines, the preservation number of which is CCTCCNO: M2019304, which can convert inorganic selenium into organic selenium, and the organic selenium content is as high as 2332 mg / kg. [0004] Invention patent application 201911406443.X discloses a grape juice Hanseniaspora uvarum strain A14 with a preservation number of CGMCCNo.18666, the strain has a high ability to produce gera...
