Methanothermus fervidus

Methanothermus fervidus is a species of methanogen.^[1] It is notable for being extremely thermophilic. Its cells are rod-shaped; its complex cell envelope exhibits two layers, each about 12 nm thick; the inner represents the pseudomurein sacculus and the outer a protein envelope. The type strain is Methanothermus fervidus Stetter 1982. The cells are motile, strictly anaerobic and stain Gram positive. They can grow at temperatures as high as 97 °C. Strain V24S^T can subsist on carbon dioxide and hydrogen alone. Its genome is 1,243,342 bp in length.^[2]
