Query: NC_009033:1283645 Staphylothermus marinus F1, complete genome
Lineage: Staphylothermus marinus; Staphylothermus; Desulfurococcaceae; Desulfurococcales; Crenarchaeota; Archaea
General Information: Hyperthermophilic archaeon. This organism was isolated from hydrothermal marine sediment from Vulcano Island in Italy. Staphylothermus marinus is heterotrophic and requires sulfur, which is reduced to H2S, for growth.
Subject: NC_015474:723553 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.
