Lineage: Natrinema pellirubrum; Natrinema; Halobacteriaceae; Halobacteriales; Euryarchaeota; Archaea
General Information: Country: Italy; Isolation: Red heat in salted hides (spoiled fish); Temp: Mesophile. Natrinema pellirubrum, formerly Halobacterium salinarium is a halophilic archaea requiring at least 1.7 M NaCl for growth and able to grow at salt concentrations of up to 4.3 M.
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.
