Selective approach to efficient ethanol production using adaptation of producer Saccharomyces cerevisiae to hyperosmotic medium

International Journal of Engineering Research and Applications
Preserved Fulltext
The resistance to ethanol of 18 strains of alcoholic yeast Saccharomyces cerevisiae, including production strains, was studied. It is shown that yeast growth was inhibited by increasing the concentration of ethanol in the medium above 7% (v/v). Successive adaptation of alcohol yeast to gradually increased concentrations of sodium chloride in the medium was carried out. Yeast variants that exceeded production strains in fermentation activity on the medium with 10% (v/v) ethanol were received.
