Abstract

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