The microbial reduction of arsenate (As(V)) significantly contributes to arsenic migration in mine stream sediment, primarily driven by heterotrophic microorganisms using dissolved organic matter (DOM) as a carbon source. This study reveals novel pathway sediments that photosensitive DOM generates photoelectrons stimulate diverse nonphototrophic reduce As(V). photoelectrophic As(V) (PEAsR) was investigated microcosm incubation, which showed the transfer from indigenous sediment microorganisms, thereby leading 50% higher rate abundance two marker genes for reduction,
