Abstract

Saccharomyces cerevisiae DFST 614 was subjected to chemical mutagenesis with 0:75% methylmethanesulfonate (ITV for one hour. Mutagenesis yielded 94 thermotolerant mutants able to grow up to 43°C. Alcohol production of the mutants at 30°C was significantly lower than of the control. However, 75% of the mutants recovered were able to undergo alcoholic fermentation at 43°C, a property not exhibited by the normal strain.
