Abstract:
From 6 stains of yeasts, Saccharomyces cerevisiae 2016 which was suitable for Cr rich yeasts fermentation was selected Concentration and additive method of CrCl 3 were investigated by liquid culture and the optimum conditions of Cr rich yeasts were obtained The optimum concentration of CrCl 3 were 5?10 4 mol/L that were added to liquid medium at the initial 8 h of culture time At this condition, the biomass of Cr rich yeasts was 1 55 g dry weight per 100 milliliter, Cr content in yeast cells was above 1100 ?g/g, the utilizable rate of Cr ion was about 60%
