Oxidative stress and antioxidant response in a thermotolerant yeast. [PDF]
Braz J Microbiol, 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

Molybdate induces thermotolerance in yeast [PDF]
Letters in Applied Microbiology, 1999 Application of a mild heat pretreatment, performed by shifting cells from 27 degrees C to 37 degrees C led to the protection of yeast cells from death due to a subsequent extreme heat shock at 53 degrees C. The presence of cycloheximide inhibited this induction of thermotolerance, indicating the involvement of de novo protein. The phosphatase inhibitor

l-Thyroxine induces thermotolerance in yeast [PDF]
Cell Stress and Chaperones, 2019 The cellular stress response (CSR) is a universal inducible reaction modulated, among others, by heat, drugs, and hormones. We aimed to investigate the role of L-thyroxine (T4) on the heat shock (HS) response in Saccharomyces cerevisiae. The CSR was evaluated by determining growth and viability of post-logarithmic phase grown yeast cultures after HS at
