Alternative Process to Post Transcriptional Modification

The Methanococcales comprise an order of marine Archaea that use H2, CO2 and formate (some species) to perform methanogenesis. All species are motile, irregular cocci and most grow chemolithotrophically. (Boone, 2003; 89) Despite their morphological and physiological similarities, the species are ecologically, genomically and phylogenetically diverse (Fig. 1). The mesophilic Methanococci (such as Methanococcus vannielii, Methanococcus voltae and Methanococcus maripaludis) grow at ambient temperatures and were isolated from marine marshes and estuaries. (Hall, 2009: 45) Thermophilic Methanococcus thermolithotrophicus, initially isolated from geothermally heated marine sediment, grows optimally at 65°C. ...
