After years of research, the molecular structure of the enzyme responsible for a large part of the global nitrate and nitrogen production by bacteria has finally been uncovered. The anammox bacterium ...

Anaerobic ammonium-oxidizing (anammox) bacteria are known for their ability to convert ammonium into nitrogen gas without using oxygen. The chemical compound hydrazine, also used as rocket fuel and ...

Limnology and Oceanography, Vol. 63, No. 2 (March 2018), pp. 687-701 (15 pages) We investigated anaerobic nitrogen (N) cycling in the water column of Lake Kivu, a deep meromictic tropical lake in East ...

Nitric oxide (NO) is a central molecule of the global nitrogen cycle. A study reveals that microorganisms can grow on NO. Their results change our view of the earth's nitrogen cycle and how ...
