NCBI: Taxonomy

Description and significance

Nitrobacter winogradsky has many differing rod shaped cells which divide through polar swelling. It contains an asymmetrical membrane system, carboxysomes along with intracellular inclusion bodies. It can grow in both aerobic and anoxic conditions.

 It is important to sequence the genome of Nitrobacter winogradskyi to see the relation between itself and other bacteria involved  in the nitrogen cycle to improve nitrogen management.

Describe the appearance, habitat, etc. of the organism, and why it is important enough to have its genome sequenced. Describe how and where it was isolated. Include a picture or two (with sources) if you can find them.

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? Does it have any plasmids? Are they important to the organism's lifestyle?

Cell structure and metabolism

Nitrobacter winogradskyi plays a key role in the nitrogen cycle by converting nitrite to nitrate. It derives its energy through nitrite oxidation and carbon dioxide fixation, which it can do simultaniously, thus acting as a chemolithoautotroph. In the absence of nitrite it uses soley carbon sources and acts as a chemoorganoheterotroph. Describe any interesting features and/or cell structures; how it gains energy; what important molecules it produces.

Ecology

It interacts with ammonium oxidizing bacteria which also plays a key role in the nitrogen cycle. Ammonium oxidizing bacteria inititaites nitrification, in which nitrite is the end product. Nitrobacter winogradskyi then proceeds to oxidize nitrite to nitrate. Describe any interactions with other organisms (included eukaryotes), contributions to the environment, effect on environment, etc.

Pathology

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

Application to Biotechnology

Does this organism produce any useful compounds or enzymes? What are they and how are they used?
