Genus

Nitrobacter winogradskyi Nb-255

NCBI: Taxonomy

Description and significance

Nitrobacter winogradsky can be found living in many soils, natural stones as well as both fresh water and salt water. They have 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 anarobic conditions with nitrate as its electron acceptor.

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

Genome structure

Nitrobacter winogradskyi has a circlular DNA chormosome with the length of 3,402,093 bp encoding 3,143 predicted proteins. The genome is make up of around 62% GC pairs. 2566 were assigned a role in catagories.

Cell structure and metabolism

Nitrobacter winogradskyi are gram negative bacteria which play 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

There is no known virulence
