Iodate (IO3–) can be abiotically reduced by Fe(II) or biotically the dissimilatory Fe(III)-reducing bacterium Shewanella oneidensis (MR-1) via its DmsEFAB and MtrCAB. However, intermediates stoichiometry between IO3– reaction relative contribution of abiotic biotic reduction biogenic MR-1 in presence Fe(III) remain unclear. In this study, we found that produced HIO I– at a ratio 1:2, followed disproportionation to IO3–. Comparative analyses wild type (WT), mutants deficient MtrCAB, sp. ANA-3 Fe(III)-citrate, oxides, clay minerals showed predominated under iron-rich conditions, while played more dominant role iron-poor conditions. Compared WT oxides minerals. The observed Fe-rich Fe-limited conditions suggests bacteria could contribute transformation iodine species enrichment natural iodine-rich environments.

The microbial transformation of iodine-bearing organic matter (OM) and iron (Fe) minerals is a critical process that controls the release iodine (I) to groundwater. However, roles functional types, OM molecular characteristics, microbe-OM interactions in mobilization remain unclear. In this study, groundwater samples with different concentrations were collected from central Yangtze River basins, China. Using 16S rRNA gene sequencing, we identified sulfur disproportionation methanogenesis as dominant metabolic processes relatively low-I (<300 μg/L) high-I (>300 groundwater, respectively. Sediment incubation experiments showed combined can promote by 87.1%. Ultrahigh-resolution characterization components revealed sulfur-disproportionating microbes may selectively metabolize bioactive (e.g., aliphatic compounds oxygen-poor highly unsaturated compounds), leaving recalcitrant N-containing oxygen-rich compounds, polyphenols, polycyclic aromatic compounds) methanogenic preferentially consume Thus, cooperative-competitive pattern between methanogens disproportionating microorganisms influence degradation potentially contribute mobilization. This study highlights process, driven biological methanogenesis, promotes enrichment alluvial-lacustrine improves our understanding genesis geogenic high-iodine systems.
