Advances in Research on the Mechanisms of Saccharomyces cerevisiae Ethanol Tolerance

Abstract:

The yeast Sacchromyces cerevisiae is most widely used for producing bioethanol in alcoholic industry due to its higher ethanol yield and fermentation rate. However, the toxic effect of accumulated ethanol is one of the main factors, which limit high ethanol production. Thus, investigating the mechanisms of yeast ethanol tolerance will provide the basis for solving the industrial problem. This article reviewed the mechanisms of Sacchromyces cerevisiae ethanol tolerance focusing on its cell physiological behaviors, structure and biochemical composition, as well as its genetic basis.
