网页The dissimilatory manganese reducing bacteria (DMRB) can reduce manganese oxides to Mn(II) through two consecutive single electron transfer reactions and the obtained Mn(II) is released into pore fluids and groundwater (Liu et al., 2020). Thus, DMRB can act as an important mediator to facilitate the rapid cycling of manganese …
