yeast, stress, osmotic pressure, temperature, oxidative stressAbstract
The production of metabolites and biomass on yeasts is performed usually under stressing conditions, mainly the ones concerning dissolved oxygen, osmotic pressure, temperature, pH and toxic compounds, amongst others. Due to their unicellular nature, yeasts usually rely on changes in their physiology and composition to deal with environmental stresses. In this review we analyzed the metabolic responses used by yeasts during industrial processes such as wine production, as well as research performed to elucidate their common physiological responses, and stressing the findings on Saccharomyces cerevisiae, which is by far the most important yeast from the industrial point of view.
