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_015703:1898159 Runella slithyformis DSM 19594 chromosome, complete genome
Lineage: Runella slithyformis; Runella; Cytophagaceae; Cytophagales; Bacteroidetes; Bacteria
General Information: Environment: Fresh water, Host; Isolation: Fresh water lake; USA, Louisiana, Baton; Temp: Psychrophile. This is a species of curved, nonflexible, pink bacteria. The species is of interest because it is able to grow at temperatures as low as 4°C. The species epithet is derived from slithy, a nonsense word from Lewis Carroll's Jabberwocky for a fictional organism that is 'slithy' and the Latin word 'suffix' meaning '-like, in the shape of', yielding the Neo-Latin word 'slithyformis' meaning 'slithy in form'.
