ABSTRACT:
A novel group of mutant yeasts and novel methods for selecting and using the mutant microorganisms are set out. A novel process for using the mutant yeasts to produce fermentation products with a lower than usual glycerol content is also disclosed. Novel beverages, including beers, wines, ales, and sake, and novel low glycerol baked goods are also possible using the novel mutants of the invention. The mutant yeasts are of the genus Saccharomyces or genus Torulaspora. The mutants are also used to isolate DNA which can be inserted into yeasts to produce transformed yeasts having either greater or smaller glycerol production. The transformed yeasts may also be used to produce novel beverages, baked goods, or glycerol.
