Query: NC_008698:471564 Thermofilum pendens Hrk 5, complete genome
Lineage: Thermofilum pendens; Thermofilum; Thermofilaceae; Thermoproteales; Crenarchaeota; Archaea
General Information: Hyperthermophilic crenarchaeota. Thermofilum pendens is a hetrotrophic hyperthermophile that has been isolated from hot springs, mud holes, and other thermal environments. This organism gets energy from the respiration of sulfur, using complex organic compounds as electron donors.
Subject: NC_000854:191705 Aeropyrum pernix K1, complete genome
Lineage: Aeropyrum pernix; Aeropyrum; Desulfurococcaceae; Desulfurococcales; Crenarchaeota; Archaea
General Information: This organism, which was the first strictly aerobic hyperthermophilic archaeon sequenced, was isolated from a coastal solfataric (volcanic hydrothermal area that gives off sulfuric gases) thermal vent at Kodakara-Jima Island, Japan in 1993. Aeropyrum pernix is an aerobic hyperthermophile. This organism grows between 70 and 100 degrees C , with optimal growth at 90-95 degrees C, pH 5-9 with a optimum of pH 7.0, and a salinity of 3.5%. This organism is highly motile and cells are often surrounded by pili-like appendages. Doubling time is 200 minutes in optimal growth conditions. It does not require sulfur-containing compounds for growth, and thus does not form hydrogen sulfide during growth.
