| 摘 要： | 酒精发酵是重要的发酵工业之一，在传统的酒精发酵过程中，菌种的酒精发酵浓度低，原料的利用率和酒精的转化率也低，能量消耗大，导致生产效率较差［１］。近年来国内外许多研究者致力于筛选和构建能产高浓度酒精和耐高浓度酒精的菌种，并把这些酿酒酵母应用于浓醪发酵生...

| Abstract: | In this paper we report the effects of Ca 2 and inositol upon growth, ethanol fermentation and ethanol tolerance of Saccaromyces cerevisiae. The result shows that by adding inositol has notable effects on growth and ethanol tolerance of Saccaromyces cerevisiae (p<0.05), but has little effects on ethanol fermentation (p=0.3933). By adding Ca 2 has remarkable effects on ethanol fermentation and ethanol tolerance (p<0.05), but has little effect on yeast growth (p=0.1544). By means of adding Ca 2 and inositol has more effects on the growth, ethanol fermentation and ethanol tolerance than the condition of only adding Ca 2 or inositol separatly. |
