【 摘 要 】

Heavy metal pollution is one of the most important environmental problems today. Thus, metal brings serious environmental pollution, threatening human health and ecosystem. In recent years, applying biotechnologies removing metal pollution became hot topic because of its potential application. Alternative process is biosorption, which utilizes various natural materials, including, yeast. The yeast biomass has been successfully used as biosorbent for removal of Ag, Au, Cd, Co, Cr, Cu, Ni, Pb, U, Th and Zn from aqueous solution. Yeasts of generaSaccharomycesare efficient biosorbents for heavy metal ions and it can be procured in large quantity at low cost..                Saccharomyces cerevisiaecan remove toxic metals, recover precious metals and clean radio-nuclides from aqueous solutions to various extents .Saccharomyces has the ability to differentiate between different metals such as selenium, antimony and mercury based on their toxicity. This low-cost biosorbent will make the process highly economical and competitive particularly for environmental applications in detoxifying effluents.
