Background | Methanocaldococcus infernus (strain DSM 11812 / JCM 15783 / ME) is an autotrophic, extremely thermophilic methanogenic archaeum isolated from a deep-sea hydrothermal chimney sample collected on the Mid-Atlantic Ridge at a depth of 3000 m. The cells are heavily flagellated, coccoid shaped and motile. It grows between 55 and 91 degrees Celsius, with an optimum growth temperature at 85 degree Celsius. The optimum pH for growth is 6.5, and the optimum sea salt concentration for growth is around 25 g/l. M. infernus uses H(2) and CO(2) as the only substrates for growth and methane production. Tungsten, selenium and yeast extract stimulate growth significantly. In the presence of CO(2) and H(2), M. infernus reduces elemental sulphur to hydrogen sulphide. This organism is closely related to Methanococcus jannaschii strain JAL-1T. (Adapted from PMID: 9734046). (HAMAP: METIM) |
