Abstract

Microorganisms and algae have potential as agents for removing inorganic pollutants from wastewaters. Metal ion uptake mechanisms function either by passive chemical adsorption or by metabolically driven processes. Ion selective uptake processes are being sought in algae to facilitate purification of valuable metal ions for recycling. Sessile macroalgae growing in seawater are useful bioindicators for detecting metal ion contamination in the marine environment.

废水中有毒金属离子的生物吸附与吸收。
微生物和藻类具有去除废水中无机污染物的潜力。金属离子摄取机制通过被动化学吸附或代谢驱动过程发挥作用。离子选择性吸收过程正在寻求藻类,以促进有价值的金属离子的净化回收。生长在海水中的无柄巨藻是检测海洋环境中金属离子污染的有用生物指标。
