Query: NC_015474:105075 Pyrococcus sp. NA2 chromosome, complete genome

Lineage: Pyrococcus; Pyrococcus; Thermococcaceae; Thermococcales; Euryarchaeota; Archaea

General Information: Pyrococcus has similar characteristics of other thermoautotrophican archaea such as Archaeoglobus, and Methanococcus in the respect that they are all thermophilic and anaerobic. Pyrococcus differs, however, because its optimal growth temperature is nearly 100 °C and dwells at a greater sea depth than the other archaea. Studying Pyrococcus helps give insight to possible mechanisms used to endure extreme environmental conditions like high temperatures and high pressure.

Subject: NC_000916:952663 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.
