| 摘 要： | 通过高效液相色谱法对3株酿酒酵母(Saccharomyces cerevisiae)发酵过程中葡萄糖、甘油、乙醇及有机酸含量进行测定分析。结果表明:S.cerevisiae1946发酵体系中甘油和乙醇的含量显著高于S cerevisiae P1和S.cerevisiae 32788发酵体系(P0.05);3株酿酒酵母发酵液中7种有机酸存在明显的差异性和规律性;S.cerevisiae 1946发酵体系中有机酸的含量低于S.cerevisiae P1和S.cerevisiae 32788发酵体系,S cerevisiae的产酸水平与产乙醇能力呈负相关关系。

| Abstract: | In this study, the contents of glucose, glycerol, ethanol and organic acids in the fermentation process of three Saccharomyces cerevisiae were determined by high performance liquid chromatography (HPLC). The results showed that the content of glycerol and ethanol in S. cerevisiae 1946 was significantly higher than that in S. cerevisiae P1 and S. cerevisiae 32788 (P<0.05). The seven organic acids in the three kinds of S. cerevisiae fermentation broth have obvious differences and regularity. The content of organic acids in S. cerevisiae 1946 was lower than that in S. cerevisiae P1 and S. cerevisiae 32788. The acid production level of S. cerevisiae was negatively correlated with ethanol production capacity. |
