Abstract:
Manganese oxides are a type of high-reactive minerals that play an important role in biogeochemical cycling of many major and trace elements. Bacteria are crucial in bio-catalyzing the formation of most naturally occurring Mn minerals. Currently, a variety of bacterial strains isolated from various habitats such as oceans, fresh waters, soils and ores have exhibited the distinctive bio-oxidation activities to convert the soluble Mn (II) oxides to the insoluble Mn (IV) ones. Here we review the research advances regarding the structures and characterization of several classes of bacterial manganese (II)-oxidizing genes, their expression regulations, the structures as well as functions of multicopper oxidases they encoded. Some raised mechanistic questions and the future research prospects are also discussed.
