The effect of salt stress on ethanol endurance of yeast cells was studied. Cells grown under increased NaCl concentrations were more ethanol tolerant than controls. The increase in trehalose content under hyper-saline conditions has been suggested to allow cells to withstand higher ethanolic conditions. There seems to be an overlap between osmotolerance and ethanol endurance in Saccharomyces cerevisiae.
