生物催化铁锰离子及其氧化物的循环转化

Microbes Catalyse the Transformation among Iron and Manganese Ions and Oxides

铁锰离子或铁锰氧化物可作为电子供体或受体被微生物催化氧化或还原,这种微生物催化作用是自然界金属循环、矿物形成与迁移的重要推动力。微生物的呼吸作用或特异性酶使铁锰氧化沉淀或还原浸出,同时其它有价金属共沉淀或浸出,所以铁锰及其氧化物的微生物循环转化作用是资源环境领域生物技术的重要的共性基础。基于对微生物催化铁锰氧化还原过程的机理探索,对自然界固有的缓慢生物过程进行人工强化、提取富集有价金属、消除环境金属污染,最终建立基于生物技术的循环经济和生态工业模式。

Iron and manganese ions and their oxides act as electron donors and acceptors to supply energy for microbes, andprompt the metals recycle of the earth crust. microbe's respiration action or enzyme support the transformation among iron andmanganese ions and oxides, this is the common foundation of resourses and environment area. It is promising to explore thetechnics of the biology process so as to recover metals, eliminate metals pollution, setting up ecotypic industry and realizng re-cycling economics.
