Query: NC_010546:1853825 Cyanothece sp. ATCC 51142 chromosome circular, complete sequence
Lineage: Cyanothece; Cyanothece; ; Chroococcales; Cyanobacteria; Bacteria
General Information: Cyanothece sp. ATCC 51142 was isolated from intertidal sands from the Gulf of Mexico in Texas. The marine diazotrophic strain, Cyanothece sp. ATCC 51142, has a robust diurnal cycle in which photosynthesis is performed during the day and nitrogen fixation at night.
Subject: NC_008819:1531187 Prochlorococcus marinus str. NATL1A, complete genome
Lineage: Prochlorococcus marinus; Prochlorococcus; Prochlorococcaceae; Prochlorales; Cyanobacteria; Bacteria
General Information: This strain was collected from the north Atlantic Ocean at a depth of 30 m and was isolated by filter fractionation. This strain belongs to the 'low light-adapted' ecotype, clade I, and has a high 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.
