Query: NC_012804:1431465 Thermococcus gammatolerans EJ3, complete genome
Lineage: Thermococcus gammatolerans; Thermococcus; Thermococcaceae; Thermococcales; Euryarchaeota; Archaea
General Information: Hyperthermophilic radioresistant marine archaeon. Thermococcus gammatolerans was isolated from hydrothermal vent chimneys located in the mid-Atlantic Ridge and Guyamas basin. When exposed to gamma radiation, this organism has a survival curve similar to Deinococcus radiodurans.
Subject: NC_010424:214640 Candidatus Desulforudis audaxviator MP104C, complete genome
Lineage: Desulforudis audaxviator; Desulforudis; Peptococcaceae; Clostridiales; Firmicutes; Bacteria
General Information: Its genome indicates a motile, sporulating, sulfate-reducing, chemoautotrophic thermophile that can fix its own nitrogen and carbon by using machinery shared with archaea. Candidatus Desulforudis audaxviator is a gram positive sulfate reducing bacteria identified in fracture water from a borehole at a depth of 2.8 km in a South African gold mine. Water from these boreholes is very old (low-biodiversity fracture water), suggesting that these bacteria have been isolated from the Earth's surface for as much as several million years.
