General Information: Isolation: Deep-sea hydrothermal chimney sample; Temp: Thermophile; Temp: 55 - 91C; Habitat: Deep sea, Marine. Hyperthermophilic methanogen. Methanocaldococcus infernus was isolated from a deep sea hydrothermal vent on the Mid-Atlantic Ridge.
Subject: NC_015474:1035834 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.
