microbial reduction of arsenate

Microbial reduction of arsenate involves certain bacteria converting arsenate (a toxic form of arsenic) into a less harmful form called arsenite. These microbes use arsenate as part of their energy process, effectively changing its chemical structure. This transformation can either detoxify arsenic in the environment or mobilize it, depending on ecological conditions. Understanding this process helps in managing arsenic contamination, as it influences how arsenic moves and persists in soils and water systems.
