“…The Mn element has 11 valence states, ranging from −3 to +7; however, only +2, +3, and +4 are naturally present in the biosphere [5]. Dissolved Mn 2+ can be found in a variety of water bodies, including surface water (rivers and lakes) [6][7][8], groundwater [9,10], and oceans [11]. Because free or dissolved Mn 3+ is extremely unstable, it is easily transformed into Mn 2+ or Mn 4+ through disproportionation [12], or an oxyhydroxide (MnOOH) is formed.…”

Groundwater serving as a drinking water resource usually contains manganese ions (Mn2+) that exceed drinking standards. Based on the Mn biogeochemical cycle at the hydrosphere scale, bioprocesses consisting of aeration, biofiltration, and disinfection are well known as a cost-effective and environmentally friendly ecotechnology for removing Mn2+. The design of aeration and biofiltration units, which are critical components, is significantly influenced by coexisting iron and ammonia in groundwater; however, there is no unified standard for optimizing bioprocess operation. In addition to the groundwater purification, it was also found that manganese-oxidizing bacteria (MnOB)-derived biogenic Mn oxides (bioMnOx), a by-product, have a low crystallinity and a relatively high specific surface area; the MnOB supplied with Mn2+ can be developed for contaminated water remediation. As a result, according to previous studies, this paper summarized and provided operational suggestions for the removal of Mn2+ from groundwater. This review also anticipated challenges and future concerns, as well as opportunities for bioMnOx applications. These could improve our understanding of the MnOB group and its practical applications.
