Sažetak
The role of biogenic elements in the metabolism of microorganisms and higher organisms is a field of particular interest today. Investigations involving the effect of mangane, copper, zinc, selenium, chromium, magnesium and other biogenic elements the prevention of certain diseases in humans and animals are of great importance. Therefiore, the aime of this study was to determine the optimal concentrations of mangan ions intensifying both, the rates of fermentation and yeast cells growth and the fermentation conditions allowing the accumulation of a desired amount of mangan ions in yeast biomass. The highest biomass concentration and ethanol production in semiaerobic and static conditions was achieved in medium with 100-125 mg/l mangan sulphate. Experiments have shown that the incorporation of mangane ions were better in semiaerobicthan in static conditions. The highest concentrations of mangan ions in yeast biomass (0.05 mg/g dry matter) was obtained in semiaerobic condition, when fermetations were performed by 35 pH-value in molasses medium.
