[The effects on ethanol fermentation of Saccharomyces cerevisiae by adding Ca2+ and inositol].

In this paper we report the effects of Ca2+ and inositol upon growth, ethanol fermentation and ethanol tolerance of Saccharomyces cerevisiae. The result shows that by adding inositol has notable effects on growth and ethanol tolerance of Saccharomyces cerevisiae (p < 0.05), but has little effects on ethanol fermentation (p = 0.3933). By adding Ca2+ 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 Ca2+ and inositol has more effects on the growth, ethanol fermentation and ethanol tolerance than the condition of only adding Ca2+ or inositol separately.
