Cellular Stress Impact on Yeast Activity in Biotechnological Processes—A Short Overview

Abstract

The importance of Saccharomyces cerevisiae yeast cells is known worldwide, as they are the most used microorganisms in biotechnology for bioethanol and biofuel production. Also, they are analyzed and studied for their similar internal biochemical processes to human cells, for a better understanding of cell aging and response to cell stressors. The special ability of S. cerevisiae cells to develop in both aerobic and anaerobic conditions makes this microorganism a viable model to study the transformations and the way in which cellular metabolism is directed to face the stress conditions due to environmental changes. Thus, this review will emphasize the effects of oxidative, ethanol, and osmotic stress and also the physiological and genetic response of stress mitigation in yeast cells.

The Effect of a Magnetic Field on the Transport of Functionalized Magnetite Nanoparticles into Yeast Cells

“…Yeast cells are used as a model in several studies to analyze processes similar to these in human cells [58,59]. Van der Laan et al [58] characterized the oxidative stress in yeast cells after internalizing fluorescent nanodiamonds proposed as free radical biosensors.…”

“…Eigenfeld et al [60] described the impact of nanoparticles on yeast cell viability and Moło ń [42] reported the antioxidant properties and toxic effect of the TEMPO spin label. Yeast cells were also applied under various cellular stress impacts, including oxidative, osmotic, and ethanol accumulation [59]. In turn, Krzyminiewski and Dobosz applied yeast cells in the study of magnetic nanoparticle uptake and the antioxidant properties of a TEMPO spin probe using ESR [16,17,32].…”
