摘  要:
从多种成熟水果的果肉、果皮、果园土壤以及自然发酵的番木瓜酒中,分离出121株酵母菌。其中从番木瓜酒中分离出一株酵母菌P3-3,该菌株在乙醇体积分数18%,SO2质量浓度300mg/L,pH2.1时能发酵产气。由该菌株发酵制成的番木瓜酒总酯含量达到6.53g/L,乙醇体积分数达到12%,而且香气浓郁、独特。经形态和分子生物学鉴定,该菌株为梅奇酵母(Metschnikowiasp.)。

摘  要:
One hundred and twenty-one yeast stains were isolated from the pericarps and pulps of various tropical and subtropical fruits,soils and papaya wine.A yeast strain named P3-3 with excellent performance for the fermentation of papaya wine was selected.This strain exhibited powerful aroma-producing and fermentation capability under the conditions of 18% ethanol,300 mg/L SO 2 and pH 2.1.Strain P3-3 could form its unique flavor.It was identified as Metschnikowia sp.and could contribute to the aroma complexity of papaya wine.
