| 摘 要： | 啤酒酵母菌对铀有较大的吸附能力,为了增加其在实际应用中的稳定性,对用甲醛交联,海藻酸钙包埋固定的这种细菌吸附铀进行了初步的研究。结果表明,啤酒酵母菌经甲醛交联后,每g最大理论铀吸附量达185 2mg,海藻酸钙包埋固定后,每g最大理论铀吸附量达769 2mg,固定化后为其今后的工业应用奠定了基础。

| Abstract: | Saccharomyces cerevisiae has great capability of biosorption of uranium. The maxium uptake is 172.4 mg/g according to this study. To adapt to the application of the biomass in the field, the biosorption of uranium by cross-linked and alginate calcium immobilized Saccharomyces cerevisiae is studied. Results indicate the maxium uptake is 185.2 mg/g by formaldehyde cross-linked biomass, and it is 769.2 mg/g by alginate calcium immobilized biomass. |
