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_002570:126500 Bacillus halodurans C-125, complete genome

Lineage: Bacillus halodurans; Bacillus; Bacillaceae; Bacillales; Firmicutes; Bacteria

General Information: Strain C-125 (JCM9153) was isolated in 1977 and is the most well studied alkaliphilic Bacillus organism. Alkaliphilic bacterium. This organism is similar to Bacillus subtilis but is alkaliphilic, grows poorly at neutral pH, and very well at pH >9.5. This bacterium produces a peptidoglycan that contains teichuronic peptides consisting of polyglutamic and polyglucuronic acids that counteract the halophilic environment.
