Query: NC_009376:2074325 Pyrobaculum arsenaticum DSM 13514 chromosome, complete genome
Lineage: Pyrobaculum arsenaticum; Pyrobaculum; Thermoproteaceae; Thermoproteales; Crenarchaeota; Archaea
General Information: Pyrobaculum arsenaticum strain DSM 13514 was isolated from a hot spring at Pisciarelli Solfatara in Italy. Arsenate-reducing hyperthermophile. Pyrobaculum arsenaticum is able to grow both chemolithoautotrophically, using hydrogen as the electron donor, to reduce arsenate, thiosulfate, or elemental sulfur, and organotrophically, using arsenate and thiosulfate as electron acceptors. Pyrobaculum arsenaticum may play an important role in the cycling of arsenic and sulfur in hyperthermal environments.
Subject: NC_020389:2288541 Methanosarcina mazei Tuc01, complete genome
Lineage: Methanosarcina mazei; Methanosarcina; Methanosarcinaceae; Methanosarcinales; Euryarchaeota; Archaea
General Information: This organism is a strictly anaerobic, non-motile, methane-producing archaeon. This organism can also aggregate forming large irregular shaped clumps of cells. Occasionally these aggregates can grow to 1000 microns or more in diameter. Growth occurs at pH 5.5-8.0, with optimum growth at pH 6.8-7.2. Growth occurs at pH 5.5-8.0, with optimum growth at pH 6.8-7.2. Can be found in decaying leaf litter, garden soil, sewage treatment sludge digestors, black mud, feces of herbivores and other urban waste and sewage products.
