Increased photosynthesis and higher plant nitrogen levels have been observed in habitats frequented by Mule Deer, Antelope, and Elk.
Denitrifying bacteria form a necessary part of the process known as denitrification as part of the nitrogen cycle, their primary purpose being to metabolise nitrogenous compounds, with the assistance of the nitrate reductase enzyme, to turn oxides back to nitrogen gas or nitrous oxides for energy generation.
They carry modified leaves offering accommodation to ants, including those of the family Dolichoderinae, and in return gain some sustenance from increased carbon dioxide and nitrogen levels, and a degree of protection from noxious animals and plants.
Side chains of the surrounding amino acids can have an effect on the binding of the nitrogen atom, mainly three Phe can affect the methyl groups bound to the nitrogen atom (not shown in figure 2).
The Elaeagnaceae often harbor nitrogen-fixing actinomycetes of the genus Frankia in their roots, making them useful for soil reclamation.
Formaldehyde fixes tissue or cells by irreversibly connecting a primary amine group in a protein molecule with a nearby nitrogen in a protein or DNA molecule through a -CH2- linkage called a Schiff base.
Nitrogen fixation, a process by which nitrogen is converted from its inert molecular form to a compound more readily available and useful to living organisms
Casuarina glauca is an actinorhizal plant producing root nitrogen-fixing nodules infested by Frankia.
FLOX, in chemistry, a combustion process said to reduce nitrogen oxide formation by suppressing peak flame temperatures

Legume cover crops are planted in the vineyard to convert nitrogen for the vine use, as well as serving as homes for beneficial insects.
This enzyme manufactures glutamate from glutamine and α-ketoglutarate, and thus along with glutamine synthetase (abbreviated GS) plays a central role in the regulation of nitrogen assimilation in photosynthetic eukaryotes and prokaryotes.
Hantzsch pyridine synthesis, multi-component organic reaction between an aldehyde a β-keto ester and a nitrogen donor
For example in 1981, shortly before the launch of the first Space Shuttle mission, two technicians lost consciousness and one of them died after they entered the Orbiter aft compartment which was pressurized with pure nitrogen as a precaution against fire.

In a televised documentary in 2007, the British political commentator (and former Member of Parliament) Michael Portillo examined execution techniques in use around the world and found them unsatisfactory; his conclusion was that nitrogen asphyxiation would be the best method.
Isobaric Counterdiffusion was first described by Graves, Idicula, Lambertsen, and Quinn in 1973 in subjects who breathed one inert gas mixture (nitrogen or neon) while being surrounded by another (helium).
Nitrogen isotope data has also been used to measure the amount of exchange of air between the stratosphere and troposphere using data from the greenhouse gas Kjeldahl
Total Kjeldahl Nitrogen or TKN is the sum of organic nitrogen, ammonia (NH3) and ammonium (NH4+) in the chemical analysis of soils.
Nitrogen-containing bisphosphate drugs used in the treatment of osteoporosis reduce farnesyldiphosphate production and thus prelamin A farnesylation.
