The present invention is directed to a generic methodology for preparing wines and other beverages having reduced ethanol content, where said wines or beverages may be sweet, dry or demi-sec beverages. The methodology comprises different fermentation stages, wherein wine yeasts Pichia anomala y Saccharomyces sp. are used. The present invention teaches a methodology, in which yeast groups are used,and said groups are capable of generating several yields of ethanol production by controlling critical variables in the production of an organoleptically acceptable wine through a minor interventionin the aromatic compounds and the final product, resulting in a wine of similar features to those ones available in the market, which has the antioxidant properties and the quality of traditional wines, with lower alcoholic content.

The invention discloses an industrial fermentation production method of raspberry ketone, comprising the following steps: (1) using natural p-coumaric acid as a raw material to generate p-hydroxybenzaldehyde under the metabolism of actinomycetes sp.OMK-74; 2) with the p-hydroxybenzaldehyde and acetone gained in step (1) as raw materials, generate 4-hydroxybenzylidene acetone under the metabolism of Bacillus sp.OMK-75; Benzylidene acetone is used as a raw material, and the raspberry ketone is reduced under the metabolism of yeast Saccharomyces sp.OMK-76. The invention realizes the high-efficiency biosynthetic production process of raspberry ketone through three-step fermentation.

The invention discloses a petroleum aromatic hydrocarbon degrading yeast G-94, which is named as Candida tropicalis in taxonomy Candida Tropicalis .G‑94, belonging to the genus Yeast, was deposited in the China Center for Type Culture Collection (CCTCC) on June 30, 2017. The deposit address is Wuhan University, China, and the deposit number is: CCTCC NO: M 2017402. The strain Obtained by screening from petroleum-contaminated soil in the oil production area of ​​Qianjiang Guanghua Oilfield, the bacterial strain G-94 is ellipsoidal, and the bacterial colony is milky white. The concentration is 0.3%, the salt concentration is 0.5%, the inoculation amount is 4%, the N source (NH 4 ) 2 SO 4 , P source K 2 HPO 4 The degradation rate of petroleum aromatic hydrocarbons reached 67.32% after 30 days of culture under the conditions of the above conditions, and it has good application prospects and economic value in eliminating petroleum pollutants and biologically remediating petroleum aromatic hydrocarbons polluted soil and polluted water bodies.
