Effect of Lipids and Oxygen on Yeast Growth and the Biosynthesis of Acetoin During Fermentation [PDF]

Journal of the Institute of Brewing, 1976
Brewery yeast needs traces of oxygen for the biosynthesis of unsaturated fatty acids and ergosterol. Owing to the increase in cell mass during primary fermentation the concentrations of these essential lipids decrease and thereby affect the physiological condition of the yeast. When the sterol concentration of whole cells has decreased to 0.2 to 0.3 mg
