Ferric iron was produced anaerobically from ferrous iron through the metabolic activity of recently described ferrous iron-oxidizing, nitrate-reducing bacteria. It was identified as poorly crystallized 2-line ferrihydrite with a particle size of 1-2 nm. This biologically produced ferrihydrite was shown to be a suitable electron acceptor for dissimilatory ferric iron-reducing bacteria in freshwater enrichment cultures, and was completely reduced to the ferrous state; no magnetite formation occurred. Geobacter metallireducens was also able to completely reduce the biologically produced ferrihydrite. These results indicate the possibility of an anaerobic, microbial cycling of iron. Using the biologically produced ferric iron, two isolates of o...
