Genus

Neptunomonas

Description and Significance

Describe the appearance, habitat, etc. of the organism, and why you think it is important.

Appearance: The genus includes rod shaped (Bacillus) or slightly curved (vibrio) cells, with approximate sizes of 0.7–0.9 × 2.0–3.0 µm.

The Neptunomonas species

Genome Structure

Describe the size and content of the genome. How many chromosomes? Circular or linear? Other interesting features? What is known about its sequence?

Cell Structure, Metabolism and Life Cycle

Interesting features of cell structure; how it gains energy; what important molecules it produces.

Metabolism: This species can receive and use resources from a wide range of carbon sources for metabolic engineering. They are aerobically respiring organisms, with selectivity anaerobic capabilities. Oxidising strains are commonly associated with polluted coastal marine sediments. Additionally, this organism is closely related to the endosymbionts of the bone-eating polychaetes in the genus Osedax, occurring in root structures produced by Osedax which penetrate the whale bone. Location and enzyme activity suggest Neptunomonas aid in the digestion of bones for the polychaete, however it is unknown yet if the resulting molecules are used in metabolic processes for the micro-organism.

Ecology and Pathogenesis

Habitat; symbiosis; biogeochemical significance; contributions to environment.

If relevant, how does this organism cause disease? Human, animal, plant hosts? Virulence factors, as well as patient symptoms.
