Subject: NC_000854:564811 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.
