Description of Methanobacterium thermoautotrophicum

taxonomy: Archaea; Euryarchaeota; Methanobacteriales; Methanobacteriaceae; Methanobacterium
Methanobacterium thermoautotrophicum is a well studied Archaeon that is ubiquitous in anaerobic environments, grows readily and rapidly under laboratory conditions, and from which in vitro methanogenic extracts and enzymes have been purified and studied for over 20 years. The organism is a moderate thermophile with an optimum growth temperature of 65 degrees, and is positioned near the `center' of the methanogen evolutionary tree. It is an `absolute' autotroph, requiring only CO2, H2 and salts for growth.
The total number of ORF of Methanobacterium thermoautotrophicum used in this study is 1872.
