| Method | "Researchers enriched phosphite-oxidizing, anaerobic bacteria in a sulphide-reduced mineral medium with sulphate as the electron acceptor, by using marine or freshwater sediments as inoculum. Growing cultures developed within 2–4 months and were transferred repeatedly into subcultures." |
| Comments | "The reduction of phosphate to phosphine (PH3) has to proceed through steps of extremely low redox potential ((HPO4) 2-/(HPO3)2-,-690 mV (HPO 3)2-/ (H2PO2)- , -913 mV (H2PO2)-/P, -922 mV P/PH3, -525 mV, at pH 7.0), so it is unlikely to drive the coupling of a respiratory process to biomass oxidation." |
