These two processes play a pivotal role in the removal of excess nitrogen from ecosystems. This research sheds light on the multi-dimensional spatial patterns of denitrification and anammox along a ...

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 ...

This study investigated a fixed bed anammox bioreactor that uses vibration techniques to treat synthetic inorganic wastewater. Continuous experiments indicated that the activity elevation period could ...

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 ...

A newly identified microbial process may be stealing nutrients from phytoplankton, the microorganisms at the base of the ocean food web (Environ. Sci. Technol. Lett. 2018, DOI: ...

Nitrate - known, for example, as plant fertilizer - is a nutrient for many biological processes such as plant growth. Nitrate salts occur on earth in large quantities (approximately 600 billion tons).
