Query: NC_000916:1417981 Methanothermobacter thermautotrophicus str. Delta H, complete
Lineage: Methanothermobacter thermautotrophicus; Methanothermobacter; Methanobacteriaceae; Methanobacteriales; Euryarchaeota; Archaea
General Information: This strain was isolated from sewage sludge in 1971 in Urbana, Illinois, USA. This organism is a strictly anaerobic, nonmotile, methane producing archeon. This organism is found in thermophilic, anaerobic sewage sludge digestors. Energy metabolism is by the reduction of carbon dioxide to methane.
Subject: NC_015847:909938 Methanococcus maripaludis XI chromosome, complete genome
Lineage: Methanococcus maripaludis; Methanococcus; Methanococcaceae; Methanococcales; Euryarchaeota; Archaea
General Information: Methanococcus maripaludis is an obligately anaerobic, mesophilic, methane-producing archaeon. Growth on hydrogen and carbon dioxide results in the production of methane as a waste product. M. maripaludis stands out among methanogenic archaea as an ideal model species because of fast reproducible growth and effective genetic tools.
