Background Ferroglobus placidus (strain DSM 10642 / AEDII12DO) is an anaerobic, hyperthermophilic archaeon isolated from hydrothermally heated marine sediment at Vulcano, Italy. F. placidus grows at neutral pH with a temperature optimum of 85 degrees Celsius. It is able to use nitrate and thiosulfate as electron acceptors, while ferrous iron, hydrogen, and sulfide can serve as electron donors. Unlike all other known Archaeoglobales, it does not reduce sulfate. When growing on nitrate, the nitrite produced can be further reduced to N2O; therefore this is the first anaerobic denitrifier to be found. Despite the high concentration of ferrous iron generally found in hydrothermal fluids, the only thermophiles previously found to oxidize ferrous iron are members of the order Sulfolobales, and they grow poorly under these conditions. F. placidus is the first anaerobic hyperthermophile found to oxidize ferrous iron. F. placidus is also capable of oxidizing acetate and aromatic compounds using ferric iron as the electron acceptor. It is the first archaeon and the first thermophile found to carry out the anaerobic oxidation of acetate, iron and of aromatic compounds.
