Abstract

|
In order to improve the productivity of ethanol by sugar-alcohol-tolerant Saccharomyces cerevisiae Dl, the effect of addition of Ca^(2+) on the alcohol fermentation was investigated. The addition of Ca^(2+) led to both the improvement of ethanol productivity and the increase of viable cell concentration. The optimal concentration of Ca^(2+) was 0.8 mM. The higher was initial concentration of glucose, the greater effect of Ca^(2+) was observed. Ethanol inhibition of growth, specific death rate in lethal concentration of ethanol, and extracellular final pH decreased by the addition of Ca^(2+). The effect of Ca^(2+) supplementation was explained by the increase of its ethanol tolerance.
