The Biological Role of Glycerol in Yeast Cells. Yeast as Glycerol Producers

This review contains information about the physiological role of glycerol as an osmoprotective and cryoprotective factor in the vital activity of yeast cells. The significance of the glycerol biosynthesis in yeast when cultured under anaerobic and microaerophilic conditions is shown. The dependence of the glycerol production by yeast on the cultivation conditions and the composition of nutrient media is discussed. The publications on glycerol production by various taxonomic yeast groups have been analyzed. Based on the studied literature material, prospects of using yeast organisms as producers of glycerol by fermentation are predicted. glycerol, yeast, hyperosmotic stress, fermentation
