Dissolved organic matter (DOM) is a crucial component of natural sediments that alters Cd sequestration. Nevertheless, how different types DOM fuel mobilization in Mn-rich has not been elucidated. In the present study, four typical DOM, fluvic acid (FA), bovine serum albumin (BSA), sodium alginate (SA), and dodecyl benzene sulfonate (SDBS), were used to amend Cd-contaminated sediment study their effects on Cd/Mn biotransformation microbial community response. The results demonstrated drive shifts enhance microbially mediated Mn oxide (MnO) reduction release. amendment terrestrial- anthropogenic-derived (FA SDBS) mainly contributed enriching Mn-reducing bacteria phylum Proteobacteria, its abundance increased by 38.16-74.47 % 56.41-73.98 %, respectively. Meanwhile, microbial-derived (BSA SA) stimulated abundances metal(loid)-resistant Firmicutes. Accompanied structure, diversity, co-occurrence network shifts, concentration oxidation-reduction potential changed, resulting enhanced mobilization. Importantly, FA release most remarkably, probably because decreased cooperative interactions between bacterial populations, stronger MnOs, higher aromaticity hydrophobicity after amendment. This linked functional communities, explored roles lake sediments.
