Query: NC_007759:723675 Syntrophus aciditrophicus SB, complete genome
Lineage: Syntrophus aciditrophicus; Syntrophus; Syntrophaceae; Syntrophobacterales; Proteobacteria; Bacteria
General Information: Syntrophus aciditrophicus SB was isolated from sludge from a sewage treatment plant in Norman, Oklahoma, USA. Syntrophic benzoate-oxidizing bacterium. Syntrophus aciditrophicus is able to ferment benzoate when grown in co-culture with hydrogen-consuming methanogens (syntrophic metabolism).
Subject: 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.
