Wickerhamomyces anomalus strain and application thereof

The invention discloses a wickerhamomyces anomalus which is preserved in China General Microbiological Culture Collection Center with preservation number of CGMCC NO.6983 on 12 December, 2012. The optimum fermentation process parameters of liquor-producing power of the strain are as follows: temperature: 29 DEG C, culture time: 59 h, inoculation amount: 5 percent, and pH: 6.5, and the alcohol content of a fermentation liquor is 2.8 percent (v/v). The optimum process parameters for the production of ethyl acetate are as follows: temperature: 28 DEG C, culture time: 65 h, inoculation amount: 5 percent, and pH: 4.5, and the content of the ethyl acetate reaches 50.2 mg/100ml. The strain not only can produce a certain amount of alcohol, but also meet the requirements of spirit to ester aroma, has double characteristics of an alcohol yeast and an ester-producing yeast, and becomes an indispensable functional bacterium during the brewing process of dry wine; and the metabolic property of the strain is important for
