The Effect of Glucose on Saccharomyces cerevisiae Cell Biosorption of Strontium under Simulation Culture Conditions

The effect of glucose on Saccharomyces cerevisiae cell biosorption of strontium under simulation culture conditions was studied in this research. The results showed that the glucose adding did not abviously increase the biosorption efficiency in 30-150 min and after 8 h. The glucose adding might stimulate the S.cerevisiae cell biosorption of strontium ions in 4-8 h for high initial strontium concentration. The results indicated that the glucose adding only stimulated S.cerevisiae cell biosorption of strontium at certain biosorption time and the biosorption process first was a physical adsorption followed bioaccumulation according to interface process and cell growth cycle under simulation culture conditions.
