title: Manganese oxidation by bacteria: biogeochemical aspects.
abstract: Manganese is an essential trace metal that is not as readily oxidizable like iron. Several bacterial groups posses the ability to oxidize Mn effectively competing with chemical oxidation. The oxides of Mn are the strongest of the oxidants, next to oxygen in the aquatic environment and therefore control the fate of several elements. Mn oxidizing bacteria have a suit of enzymes that not only help to scavenge Mn but also other associated elements, thus playing a crucial role in biogeochemical cycles. This article reviews the importance of manganese and its interaction with microorganisms in the oxidative Mn cycle in aquatic realms.
