Query: NC_015474:644552 Pyrococcus sp. NA2 chromosome, complete genome
Lineage: Pyrococcus; Pyrococcus; Thermococcaceae; Thermococcales; Euryarchaeota; Archaea
General Information: Pyrococcus has similar characteristics of other thermoautotrophican archaea such as Archaeoglobus, and Methanococcus in the respect that they are all thermophilic and anaerobic. Pyrococcus differs, however, because its optimal growth temperature is nearly 100 °C and dwells at a greater sea depth than the other archaea. Studying Pyrococcus helps give insight to possible mechanisms used to endure extreme environmental conditions like high temperatures and high pressure.
Subject: NC_009454:1042592 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.
