Methanothermobacter marburgensis

Methanothermobacter marburgensis is a thermophilic and obligately autotrophic methanogenic archaeon. The type strain MarburgT was isolated from sewage sludge in the vicinity of the city Marburg, Germany.[1] It was also detected in hot springs. It grows in the temperature between 45 and 70 °C with optimum at 65 °C thus it is classified as thermophile. Cells are rods with length 3–3.5 μm and 0.3–0.4 μm wide, Gram-positive and non-motile. Its genome has been sequenced.[2]

They reduce carbon dioxide with hydrogen into methane as the only pathway for ATP production. It does not require any organic supplements and it grows on mineral media with CO2 as a carbon source, H2 as a source of electrons, NH3 as a nitrogen source, and sulfide as a sulfur source (obligate autotroph). The metabolism of Methanothermobacter marburgensis strain Marburg has been reconstructed in the form of an experimentally validated computer model.[3]
