Abstract

The effect pH on the growth of CSI-l strain of Saccharomyces cerevisiae as well as its ethanol productivity was studied by using batch fermentation. The growth and theethanol productivity efficiency of yeast strain was studied with two conditions which were at pH 8 and pH 9. From this study, Saccharomyces cerevisiae CSI-l strain is classified as alkaliphile or alkalitolerant organisms due to its ability to grow and ferment sugar at high pH. Ethanol productivity was determined for both pH. Study shows that fermentation conducted at pH 8 shows quite high fermentation efficiency which was 70.07%. Although there are slightly different if compared to fermentation conducted at optimum condition, however, fermentation conducted at alkaliphilic condition can reduce the possibility of contamination.
