Summary A temperature-sensitive osmophilic mutant of Zygosaccharomyces rouxii, OS15, was isolated, which required high salt or sugar concentration for growth above 30°C. Cell viability at 35°C in the presence of NaCl was higher than in the absence of NaCl, and a survival ratio of the mutant cells after incubation at 55°C was also higher in the presence of NaCl than NaCl-free condition. Furthermore, resistance to UV light, hygromycin B and geneticin was improved in the presence of NaCl. There was no difference between the parent and the mutant in fatty acid saturation and microscopic cell shape under NaCl condition.
