The World’s Nitrogen Fixation, Explained
Yale University scientists may have cracked a part of the chemical code for one of the most basic, yet mysterious, processes in the natural world — nature’s ability to transform nitrogen from the air ...
New Evidence Emerges On The Origins Of Life On Earth
In the beginning, there were simple chemicals. And they produced amino acids that eventually became the proteins necessary to create single cells. And the single cells became plants and animals. Recen...
Nitrogen fixation
Nitrogen fixation is a process in which nitrogen (N2) in the atmosphere is converted into ammonium (NH4). Atmospheric nitrogen or molecular nitrogen (N2) is relatively inert: it does not easily react...

Nitrification
Nitrification is the biological oxidation of ammonia or ammonium to nitrite followed by the oxidation of the nitrite to nitrate. The transformation of ammonia to nitrite is usually the rate limiting s...
Denitrification
Denitrification is a microbially facilitated process of nitrate reduction (performed by a large group of heterotrophic facultative anaerobic bacteria) that may ultimately produce molecular nitrogen (N...
