Abstract

Ageing in Saccharomyces cerevisiae is a finite phenomenon, determined by replicative, rather than chronological lifespan. Yeast physiological condition is known to influence industrial fermentation performance, however, until recently cellular senescence(definition) has not been considered as a brewing yeast stress factor. A polyploid lager yeast (BB11) and a brewery isolate, exhibiting petite mutation were analysed for longevity. It was observed that mitochondrial deficiency induced a reduction in lifespan. In addition, replicative capacity was perceived to be dependent on environmental conditions.
