Query: NC_015680:1475917 Pyrococcus yayanosii CH1 chromosome, complete genome
Lineage: Pyrococcus yayanosii; Pyrococcus; Thermococcaceae; Thermococcales; Euryarchaeota; Archaea
General Information: Pyrococcus yayanosii CH1 is the first obligate piezophilic hyperthermophilic archaeon isolated from the deep-sea hydrothermal site Ashadze on the mid-Atlantic ridge at a depth of 4,100 m. This organism grows within a temperature range of 80 to 108 degrees C and a hydrostatic pressure range of 20 to 120 MPa, with optima at 98 degrees C and 52 MPa, respectively.
Subject: NC_002607:1868371 Halobacterium sp. NRC-1, complete genome
Lineage: Halobacterium; Halobacterium; Halobacteriaceae; Halobacteriales; Euryarchaeota; Archaea
General Information: Chemoheterotrophic obligate extreme halophilic archeon. This microbe (strain ATCC 700922) is an obligately halophilic archeon that has adapted to growth under conditions of extremely high salinity. Motility is via tufts of polar flagella and intracellular gas vesicles are used for buoyancy. This organism grow aerobically and its ease of culturing combined with the availability of established methods of genetic manipulation in the laboratory make it an ideal model organism for study of the archaea.
