Saccharomyces cerevisiae was the first eukaryotic organism to have its genome sequenced and has been used for several decades as a model for cellular and molecular studies. The yeast S. cerevisiae is the most important microorganism used in the biotechnological industries. During alcoholic fermentation, the yeast S. cerevisiae cells are exposed to several stress conditions that may decrease their viability, including osmotic stress, high temperature and accumulation of ethanol over the process; thus, stress tolerant yeast strains with a high ethanol production are desirable to achieve high productivity. High hydrostatic pressure (HHP) stress may influence important physiological and biochemistry processes in S. cerevisiae in a similar way to others stress including oxidative stresses.
