Abstract: | Summary In a strain ofSaccharomyces cerevisiae, acetic acid at concentrations up to 1% (v/v) depressed the tolerance to added ethanol, from 11% (v/v) down to zero, and simultaneously narrowed the temperature range of growth from 3–42°C to 19–26°C. In addition, acetic acid shifted the associative temperature profile of growthand death to lower temperatures, and depressed the growth yield on glucose. |
