Microbes that couple growth to the reduction of manganese could play an important role in the biogeochemistry of certain anaerobic environments. Such a bacterium, Alteromonas putrefaciens MR-1, couples its growth to the reduction of manganese oxides only under anaerobic conditions. The characteristics of this reduction are consistent with a biological, and not an indirect chemical, reduction of manganese, which suggest that this bacterium uses manganic oxide as a terminal electron acceptor. It can also utilize a large number of other compounds as terminal electron acceptors; this versatility could provide a distinct advantage in environments where electron-acceptor concentrations may vary.
能将生长与锰的还原作用联系起来的微生物可能在某些厌氧环境的生物地球化学过程中发挥重要作用。这样一种细菌，即腐败交替单胞菌MR-1，仅在厌氧条件下将其生长与锰氧化物的还原作用联系起来。这种还原作用的特征与锰的生物还原而非间接化学还原相一致，这表明该细菌将锰氧化物用作末端电子受体。它还能利用大量其他化合物作为末端电子受体；这种多功能性在电子受体浓度可能变化的环境中可能会提供明显的优势。
