Mechanism of enhanced salt tolerance in Saccharomyces cerevisiae by CRZ1 overexpression.

ABSTRACT: Achieving high-gravity fermentation in the industrial production of fuel ethanol, and enhancing the fermentation efficiency of high-salt raw materials, such as waste molasses, can significantly reduce wastewater output and process costs. Therefore, the development of hyperosmotic-tolerant industrial Saccharomyces cerevisiae strains, capable of resisting high-salt stress, offers both environmental and economic benefits. Our previous study highlighted the potential of CRZ1 overexpression as a strategy to improve the yeast strain's resistance to high-salt stress, however, the underlying molecular mechanisms remain unexplored. The fermentation capabilities of the CRZ1-overexpressing strain, KCR3, and its parental strain, KF7, were evaluated under condition of 1.25 M NaCl at 35 °C. Compared to
