Nitrococcus mobilis is a chemoautotroph. The energy required for metabolism comes from chemical reactions of reducing nitrogen from nitrite to nitrate. They are aerobic as oxygen is the final electron acceptor. It is an autotroph because it is able to fix inorganic carbon (CO2).
Nitrococcus mobilis is an obligate chemoautotroph. The energy required for metabolism comes from chemical reactions of reducing nitrogen from nitrite to nitrate. They are aerobic as oxygen is the final electron acceptor. Inorganic carbon is its carbon source, making it an autotroph.
 
When free floating in the ocean, Nitrococcus mobilis exists as a single or diploid cell. If the cells can form a biofilm then several hundred will form aggregates on a slime layer.

Nitrococcus mobilis

Description and Significance

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

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. Nitrococcus mobilis is an obligate chemoautotroph. The energy required for metabolism comes from chemical reactions of reducing nitrogen from nitrite to nitrate. They are aerobic as oxygen is the final electron acceptor. Inorganic carbon is its carbon source, making it an autotroph.

When free floating in the ocean, Nitrococcus mobilis exists as a single or diploid cell. If the cells can form a biofilm then several hundred will form aggregates on a slime layer.

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.
