Summary
The supplementation of a simple medium with 2% soy flour increased the final ethanol concentration and the rate of fermentation bySaccharomyces bayanus. This improvement could not be attributed to an increase of ethanol tolerance of yeast cells but to the satisfaction of nutritional deficiencies.
