Abstract excerpt
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 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...
