摘要: 对内蒙古西部地区分离得到的6株酿酒酵母进行了发酵特性的比较。首先对酵母进行了耐酒精、耐SO2、耐低温、耐低pH、耐高糖和耐高盐的测试,随后进一步通过葡萄汁的发酵实验,分析比较了菌株的发酵力、酒精度、残糖量、总酸和挥发酸含量等理化指标,最终筛选出两株发酵性能优良的菌株,有望应用于内蒙古西部地区特色葡萄酒的生产。

Abstract: This study compared the fermentative characteristics of 6 strains of Saccharomyces cerevisiae isolated from western area of Inner Mongolia. Firstly, the resistances of these strains on alcohol, SO2, low temperature, low pH, glucose and salt were tested;then fermentative experiment was performed by seeding these strains respectively into grape juice, the following physical and chemical indexes were measured and compared:the fermenting power of these strains, the alcoholic strength, the residual sugar, the content of total acid and volatile acid in fermentation liquor. On the basis of above experimental results, 2 strains of S. cerevisiae with excellent fermentative characteristics were screened, and they are expected to be utilized in producing indigenous wine in the western area of Inner Mongolia.

Key words: wine, Saccharomyces cerevisiae, fermentative characteristics
