Oxidative stress and antioxidant response in a thermotolerant yeast [PDF]
Brazilian Journal of Microbiology, 2017 Stress tolerance is a key attribute that must be considered when using yeast cells for industrial applications. High temperature is one factor that can cause stress in yeast. High environmental temperature in particular may exert a natural selection pressure to evolve yeasts into thermotolerant strains. In the present study, three yeasts (Saccharomyces
