Redox cycling of iron plays a pivotal role in both nutrient acquisition by living organisms and the geochemical elements aquatic environments. In nature, is mediated microbial Fe(II)-oxidizers Fe(III)-reducers or through interplay biotic abiotic transformation processes. Here, we unveil specific process driven one single phototrophic species, Rhodobacter ferrooxidans SW2. It exhibits capability to reduce Fe(III) during bacterial cultivation. A c -type cytochrome identified with Fe(III)-reducing activity, implying linkage reduction electron transport system. R. SW2 can mediate redox transformation, depending on availability light and/or organic substrates. Iron anoxygenic photoferrotrophs proposed exist worldwide modern ancient Our work not only enriches theoretical basis nature but also implies multiple roles
