Resumen
An intergeneric osmotolerant hybrid yeast, PB2, was used together with the parental strains to study glycerol and arabitol production in batch culture. This fusion product was previously obtained by protoplast fusion between Torulaspora delbrueckii and Saccharomyces cerevisiae. Polyols and biomass production were determined in batch culture under aerobic conditions. Under the conditions tested, using PB2 hybrid and both parental strains, the best results were obtained with the hybrid. Arabitol reached a final concentration of 70 g/l and glycerol was increased to up to 50 g/l.
