Query: NC_015931:134601 Pyrolobus fumarii 1A, complete genome
Lineage: Pyrolobus fumarii; Pyrolobus; Pyrodictiaceae; Desulfurococcales; Crenarchaeota; Archaea
General Information: Environment: Deep sea, Hydrothermal vent, Marine; Isolation: Hydrothermally heated black smoker wall; Temp: Hyperthermophile; Temp: 106C. Pyrolobus fumarii is an obligate chemolithotroph, gaining energy from the oxidation of hydrogen. This organism can grow at temperatures as high as 113 degrees C.
Subject: 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.
