Query: NC_011653:1226035 Thermosipho africanus TCF52B, complete genome
Lineage: Thermosipho africanus; Thermosipho; Thermotogaceae; Thermotogales; Thermotogae; Bacteria
General Information: This organism was isolated from the Troll oil formation in the North Sea. Thermosipho africanus, a member of the Thermotogales, has the characteristic morphology of one or more cells contained in a sheath-like envelope which extends beyond the cell wall. Preliminary sequencing of Thermotogales genomes has identified extensive horizontal gene transfer between these organisms and the Archaea. Thermosipho africanus has been isolated from marine hydrothermal systems and oil reservoir production waters.
Subject: NC_009091:1423677 Prochlorococcus marinus str. MIT 9301, complete genome
Lineage: Prochlorococcus marinus; Prochlorococcus; Prochlorococcaceae; Prochlorales; Cyanobacteria; Bacteria
General Information: This strain was isolated from the Sargasso Sea at a depth of 90 m (34o 45.5'N; 66o 11.1'W). This strain belongs to the 'high light-adapted' ecotype, clade II, and has a low Chl b/a2 ratio. Marine cyanobacterium. This non-motile bacterium is a free-living marine organism that is one of the most abundant, as well as the smallest, on earth, and contributes heavily to carbon cycling in the marine environment. This cyanobacterium grows in areas of nitrogen and phosphorus limitation and is unique in that it utilizes divinyl chlorophyll a/b proteins as light-harvesting systems instead of phycobiliproteins. These pigments allow harvesting of light energy from blue wavelengths at low light intensity.
