自然界中锰氧化物的形成主要是通过微生物作用,而锰的微生物氧化机制较为复杂,除了多铜氧化酶、过氧化物酶外,最近发现微生物生成的超氧化物可能也参与了锰的氧化.微生物生成的生物锰氧化物具有较高的吸附氧化活性,其微观结构和活性会随时间快速变化.比如,锰的生物氧化初级产物具有强的诱导Mn(Ⅱ)氧化的活性,而次级产物则几乎没有.锰的生物氧化过程复杂而又广泛进行着,尤其在含锰水体的处理单元中发挥着重要的净水作用,为了深刻理解生物锰氧化物,对锰氧化细菌和真菌、锰生物氧化机理、生物锰氧化物的吸附氧化特征及潜在的工程应用等当前研究热点问题进行了综述.
In nature, the formation of manganese oxide mainly through the role of microorganisms, and manganese microbial oxidation mechanism is more complex, in addition to copper oxidase, peroxidase, the recent discovery of microorganisms to produce superoxide may also be involved in the oxidation of manganese. For example, the primary products of biooxidation of manganese have a strong activity of inducing oxidation of Mn (II), and the secondary products of biooxidation of manganese (II) have higher activities of adsorption and oxidation, and their microstructure and activity change rapidly with time There is almost no .Biological oxidation process of manganese complex and widespread, especially in the manganese-containing water treatment unit plays an important role in water purification, in order to understand the biological manganese oxide, manganese oxide bacteria and fungi, manganese Oxidation mechanism, adsorption and oxidation characteristics of biological manganese oxide and potential engineering applications are reviewed.
