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 based on DNA homology. 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 Hyphomonas 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) Hyphomonas bacteriums are Gram-negative and as a bacterium belong to alpha-Proteobacteria, which contains over 50 genera, the outer membrance mainly composed of lipopolysaccarides.
