Sulfate‐reducing bacteria oxidize phosphite (P III ) to phosphate (P V ) . This was established for bacteria isolated from marine sediments. The reaction might form part of a hypothetical phosphate cycle. It is possible that the free energy of oxidation is conserved as energy‐rich acylphosphate through a primeval stepwise substrate phosphorylation. In anoxic marine sediments of the Pacific near the Oregon coast a syntrophic community of sulfate reducers and methanogens has been identified, which anaerobically oxidizes methane to CO 2 under the formation of sulfide.
