''Genus species''


Hyphomonas neptunium is a marine prosthecate, which refers to an organism having a stalk or an appendage. Hyphomonas neptunium, as one of the eight species of the genus Hyphomanas, was frist isolated from the seawater of Barceloan, Spain. It was orginally named Hyphomicrobium neptium, but later was amended to its current name. DNA-DNA hybridization information showed a closer relationship to Hyphomanas Polymorpha(Pongratz.1957) and also lacks the ability to utilize C1 molecules as carbon source furthur supports its closer relationship to Polymorpha. Pongratz in 1957 first described the genus Hyphomans upon isolation a budding prostecate bacterium from the nasal mucus of a diver with infectitious sinusitis. Hyphomaonas is unique in the sense that it does not devide by binary fusion but, rather devides by asymmetrical budding. The mother cell are non-motile while the daughters are motile, until they become mother cells themselves. (hyphomonas.com)
===Cell Structure and Description===
Hyphomonas bacteriums are Gram-negative and as a bacterium belong to Proteobacteria, the outer membrance mainly composed of lipopolysaccarides.

Metabolism

Hyphomonas neptunium is a heterotrophic organism that uses a wide range of substrates including nitrogen as the main energy source of metabolism. Hyphomonas species catabolize proteins and amino acids, however, they cannot utilize C1 as their carbon source. They also require an absolute <1% salt formulations.

Ecology

Hyphomonas neptunium is a marine prostecate. Generally, prostecate and budding bacteria are found virtually everywhere, including some of the most extreme places like Antazrctic sea ice, ocean hydrothermal vents and even in soils. Many species are oligotrophic. Currents studies suggest that Hyphomonas play important roles in biofilm formation by production of localized capsule, extracellular, polymeric substances.
