Query: NC_012438:1600534 Sulfurihydrogenibium azorense Az-Fu1 chromosome, complete genome Lineage: Sulfurihydrogenibium azorense; Sulfurihydrogenibium; Hydrogenothermaceae; Aquificales; Aquificae; Bacteria General Information: This strain was isolated from a terrestrial hot spring in the Azores, where it was living at temperatures between 65 degrees C and 70 degrees C. Hydrogen-oxidizing thermophile. Sulfurihydrogenibium azorense is a thermophilic bacterium that is able to use hydrogen and sulfur compounds as electron donors. This organism is also able to use ferric iron and arsenate as electron acceptors. This is the first pure culture terrestrial member of the Aquificales group, isolated by dilution-to-extinction methods.

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.
