Nitrobacter fixes carbon dioxide via the Calvin cycle for their carbon requirements.
2.
"Nitrobacter " may either be rod shaped, pear-shaped or pleomorphic.
3.
"Nitrobacter " plays an important role in the nitrogen cycle by oxidizing nitrite into nitrate in soil.
4.
For example, nitrifying bacteria such as " Nitrobacter " oxidize nitrite to nitrate, donating the electrons to oxygen.
5.
The second step ( oxidation of nitrite into nitrate ) is done ( mainly ) by bacteria of the genus " Nitrobacter " and " Nitrospira ".
6.
The most common bacteria responsible for the two step conversion are the autotrophic organisms, " Nitrosomonas " and " Nitrobacter ", and many different heterotrophs.
7.
The compartment is composed of a mix of Nitrosomonas and Nitrobacter which oxidise NH 4 + to NO 2 " and NO 2 " to NO 3 " respectively.
8.
Nitrite-oxidizing bacteria, especially Nitrobacter, oxidize nitrite to nitrate, which is extremely mobile in soils because of its negative charge and is a major cause of water pollution from agriculture.
9.
"Nitrobacter " have an optimum pH between 7.3 and 7.5, and will die in temperatures exceeding 120 �F ( 49 �C ) or below 32 �F ( 0 �C ).
10.
In the oceans, this step is not as well understood as the first, but the bacteria " Nitrospina " and " Nitrobacter " are known to carry out this step in the sea.
