A comparative study of ethanol production by Issatchenkia orientalis strains under stress conditions

J Biosci Bioeng. 2012 Jan;113(1):76-8. doi: 10.1016/j.jbiosc.2011.09.004. Epub 2011 Oct 20.


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 Na₂SO₄ and Na₂SO₄ 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., 50 g/l Na₂SO₄ at pH 2.0, or at high temperatures, e.g., 43°C, when compared with other strains.
