Short summary
In this study we show increasing organic matter (OM) content on ferrihydrite surfaces enhances Fe reduction by the model Fe reducer S. oneidensis and a microbial consortia extracted from peat. Similarities in reduction rates between S. oneidensis and the consortia suggest electron shuttling dominates in OM-rich soils. Community profile analyses showed enrichment of fermenters with pure ferrihydrite, whereas OM–mineral complexes favored enrichment of Fe-reducing Desulfobacteria and Pelosinus sp.
