Synthesis of ergosterol and activity of brewing yeasts.Peer-reviewed article

T. GINOVA-STOLJANOVA, V. JENEVA

The synthesis of ergosterol was tested with three yeast strains on laboratory and plant scale under different conditions of fermentation. The relations among ergosterol synthesis, biomass growth and glycogen metabolism were determined. The results show that the rate of fermentation depends on the content of ergosterol in the inoculated yeasts. The content of unsaturated lipids in cells and wort significantly affects the cell physiology - multiplication and growth of cells, an utilization of nutrients and a production of metabolites. The lipid composition of yeasts is the factor with whom the fermentation can be controlled.(In Czech, English summary only)
