Query: NC_008358:1861505 Hyphomonas neptunium ATCC 15444, complete genome Lineage: Hyphomonas neptunium; Hyphomonas; Hyphomonadaceae; Rhodobacterales; Proteobacteria; Bacteria General Information: Marine member of dimorphic prosthecate bacteria. This organism is also known as Hyphomicrobium neptunium. It has a biphasic life style, which consists of a motile phase of flagellated swarmer cells, and a cessile phase in which a long prosthecate is produced at one end of the bacteria through which budding cells emerge. Newly budded cells in turn produce flagella and go through a motile phase and the cycle continues. These organisms can colonize the surfaces of marine environments which enables additional species to colonize at later stages. This organism may be of use in treatment of water as they attach to a solid surface and are capable of degradation of a number of pollutants including aromatic hydrocarbons, dimethyl sulfoxide and methyl chloride.

General Information: The cyanobacterium Synechococcus sp. PCC 7002 (formerly known as Agmenellum quadruplicatum strain PR-6) was originally isolated in 1961 by Chase Van Baalen from an onshore, marine mud flat sample derived from fish pens on Maguyes Island, La Parguera, Puerto Rico. The organism grows in brackish (euryhaline/marine) water and is unicellular but tends to form short filaments of two to four cells during exponential growth at the temperature optimum of 38 degrees C. The strain is extremely tolerant of high light intensities and has been grown at light intensities equivalent to two suns. This unique combination of physiological and genetic properties have long made this strain an important model system to studies of the oxygenic photosynthetic apparatus, the regulation of carbon and nitrogen metabolism, and other aspects of cyanobacterial physiology and metabolism.
