Geochemical evidence suggests that the primary terminal electron acceptors for organic matter decomposition in an-aerobic sediments are nitrate, Mn(IV), Fe(III), sulfate, and carbon dioxide (40). It is frequently reported that there are distinct zones in sediments in which the metabolism of organic matter is coupled to the reduction ...Microbial oxidation and reduction of manganese ...The manganese oxides previously formed under aerobic conditions are reduced and soluble manganese (Mn(II)) migrates into the aquifer. If the subsurface sediments are coarse-grained, the aquifer is well aerated, allowing the re-oxidation of Mn(ll) by the oligotrophic attached bacteria in aquifer sediments. If the aquifer is confined, aeration is not sufficient for Mn-reoxidafion. Mn(II) remains ...Manganese acting as a high-performance heterogeneous ...· Manganese acting as a high-performance heterogeneous electrocatalyst in carbon dioxide reduction.
