Query: NC_017506:1507943 Marinobacter adhaerens HP15 chromosome, complete genome Lineage: Marinobacter adhaerens; Marinobacter; Alteromonadaceae; Alteromonadales; Proteobacteria; Bacteria General Information: Country: Germany; Environment: marine water; Temp: 15C; Habitat: temperate shelf and sea biome; Isolation:German Wadden Sea. The marine bacterium strain HP15 was isolated from the German Wadden Sea. In order to isolate exclusively attached bacteria, aggregates (0.1 to 1 mm in diameter) were collected on a plankton net (0.1 mm pore size) from surface waters of 15 degrees C. Marine aggregates are densely colonized by bacteria from different taxonomic groups. Inter-specific interactions such as inhibition are important for colonization by aggregate-associated bacteria and thus affect the turnover of organic matter in the oceans. Strain HP15 is a colonizing bacterium which belongs to the Alteromonadaceae family within the class Gammaproteobacteria.

General Information: This is the type strain for this organism, which was isolated from a hydrothermal vent at a depth of 1300 m from the Lo'ihi Seamount southeast of Hawaii. This organism grows optimally in salt concentrations of 7.5 to 10%. Genome comparison has suggested that the bacterium has maintained its amino acid transport and degradation systems but lost sugar transport and certain sugar metabolic genes suggesting that it lives on amino acids rather than sugars. This may be in keeping with the environment this organism grows in, which is at hydrothermal deep sea vents that are characterized by collections of proteinaceous particles. This organism may colonize these particles by producing exopolysaccharides.
