Query: NC_003551:860862 Methanopyrus kandleri AV19, complete genome
Lineage: Methanopyrus kandleri; Methanopyrus; Methanopyraceae; Methanopyrales; Euryarchaeota; Archaea
General Information: Thermophilic methanogenic archaeon. This organism has been found at Guaymas hot vents at a depth of 2000, at a depth of 1006 m on the Kolbeinsey Ridge north of Iceland and on hydrothermically heated black smoker walls at a depth of 3650 m at the Mid-Atlantic Ridge. This methanogen grows chemolithoautotrophically at 80-110ºC in a hydrogen-carbon dioxide atmosphere.
Subject: NC_009454:489954 Pelotomaculum thermopropionicum SI, complete genome
Lineage: Pelotomaculum thermopropionicum; Pelotomaculum; Peptococcaceae; Clostridiales; Firmicutes; Bacteria
General Information: This type strain was isolated from granular sludge from a thermophilic upflow anaerobic sludge blanket (UASB) reactor. It was isolated both in pure culture and in co-culture with methanogens. In syntrophic association with hydrogenotrophic methanogens, this species can utilize propionate, ethanol, lactate, ethylene glycol, 1-butanol, 1-propanol, 1-pentanol and 1,3-propanediol. This is the first mesophilic, syntropic propionate-oxidizing species known which is not a member of the delta-proteobacteria.
