“The ethanol extracts of Phyllanthus reticulatus, Coldenia procumbens, Thespesia populnea and Senna alata significantly lowered the release of ergosterol by 16.37, 19.53, 24.79, and 21.44%, respectively.”
“A total of 140 mutants were selected for ethanol fermentation testing, and a significant positive correlation between ergosterol content and ethanol production was observed.”

“Our results quantitatively show the concentration regime where ergosterol protects the membrane by reducing the membrane fraction that is interdigitated in the presence of ethanol.”

“The 25 mol % ergosterol system shows a similar level of interdigitation for the 0 and 10 vol % ethanol solutions, indicating that ergosterol molecules in this system are able to effectively counteract the disruptive behavior of ethanol molecules.”

“These data … that ergosterol and cholesterol do enhance survivability … to high concentrations of ethanol and provide evidence that the appearance of the interdigitated (L(beta)I) phase bilayer is a major factor … of cellular activity, which typically occurs between approximately 12 and approximately 16 vol% ethanol in yeast fermentations.”

“An exogenous ternary complex composed of Tween 80, ergosterol , and albumin increased the final ethanol concentration of fermentation by sake yeasts from 17.2 to 19.0% (vol/vol) and reduced the fermentation time from 30 to 25 days.”
“Likewise, a complex of monoolein, albumin, and either ergosterol or ergosteryl oleate increased the final ethanol concentration of fermentation to 19.7 or 19.8% (vol/vol), respectively, and reduced the fermentation time to 25 days.”
