Using anaerobic respiration
Three nitrogen-containing nutrients in the biosphere are proteins, nucleic acids (DNA and RNA), and amino acids. Nitrogen is an essential component of these molecules and is crucial for the growth and development of living organisms.
Amino acid
An enrichment medium for isolating detergent-degrading bacteria from soil can be prepared by adding detergent as the sole carbon source. Other necessary nutrients like nitrogen and minerals should also be included to support bacterial growth. Additionally, a selective agent can be added to suppress the growth of non-detergent-degrading bacteria and promote the growth of the desired bacterium.
Amino acids are the nitrogen-containing building blocks of proteins. They are essential for the synthesis of proteins in living organisms.
There are 3 unpaired electrons in an isolated nitrogen atom, the nitrogen molecule has none.
An example of nitrogen-fixation bacterium is Rhizobia.

Nitrification can occur in drinking water. In water distribution systems where chloramines are used as the secondary disinfectant, the presence of free ammonia can sometimes act as a substrate for ammonia-oxidizing microorganisms. The subsequent reactions can lead to the depletion of the disinfectant residual in the system.

Legumes "fix" nitrogen in nodules on their roots, so they do not need additional nitrogen-containing fertilizers.

Nitrogen was first isolated by Daniel Rutherford in Edinburgh University.
Containing nitrogen
The decomposition of nitrogen-containing molecules into ammonia involves breaking the bonds within the nitrogen-containing molecule and forming new bonds to produce ammonia (NH3). This process typically requires high temperatures and/or catalysts to facilitate the reaction.
Compounds containing nitrogen and oxygen are called nitrogen oxides. These compounds can have various chemical properties and can be produced through the combustion of fossil fuels or industrial processes.
