The ability of 13 strains of multi-stress-tolerant Issatchenkia orientalis yeast to produce ethanol was examined under different stress conditions, including conditions of elevated H<SUB>2</SUB>SO<SUB>4</SUB> and Na<SUB>2</SUB>SO<SUB>4</SUB> concentrations and increased heat. The MF-121 strain produced a significant amount of ethanol after the incubation in acidic media containing high concentrations of salt, e.g., 50g/l Na<SUB>2</SUB>SO<SUB>4</SUB> at pH 2.0, or at high temperatures, e.g., 43<SUP>o</SUP>C, when compared with other strains.
