Sugar induces death of the bottom fermenting yeast Saccharomyces pastorianus

J Biosci Bioeng. 2009 Jul;108(1):60-2. doi: 10.1016/j.jbiosc.2008.12.022.

Abstract

We confirmed that sugar-induced cell death (SICD) occurs in the bottom fermenting yeast Saccharomyces pastorianus under anaerobic conditions and that mitochondrial DNA is only partly required for SICD. Fermentation tests using different ratios of glucose and non-glucose nutrients demonstrated that SICD is influenced by the balance between these nutrients.
