Abstract
Saccharomyces cerevisiae was fused with heat-treated protoplasts of an osmo tolerant yeast, Torulaspora delbrueckii, to obtain hybrids having increased tolerance to increased glucose concentrations (up to 700 g l(-1)). The pro duction of glycerol and arabitol by the hybrids was within the range of tho se of the parental strains, but the production of ethanol was higher.
