Human activities add large quantities of nitrogen to the environment, much of which gets washed into streams and rivers.

Three methods for assaying nitrification and denitrification were compared in agricultural field plots in the Southeastern USA. Nitrification was measured using the chlorate inhibition enzyme assay, ...

Underground environments like soil and aquifers teem with microbial life. These tiny microbes play a big role in cycling ...

After more than a decade of inquiry, a Princeton-led team of scientists has turned the tables on a long-standing controversy to re-establish an old truth about nitrogen mixing in the oceans. For ...

Limnology and Oceanography, Vol. 54, No. 1 (Jan., 2009), pp. 132-144 (13 pages) One of the shallowest, most intense oxygen minimum zones (OMZs) is found in the eastern tropical South Pacific, off ...

Some microbes living on sand grains use up all the oxygen around them. Their neighbors, left without oxygen, make the best of it: They use nitrate in the surrounding water for denitrification -- a ...

During combustion - one of the most popular industrial processes across all industry sectors - the chemical energy in fuels, such as natural gas, coal, or oil, is converted into heat by oxidization.

Denitrification bioreactors are engineered systems designed to remove nitrate from contaminated waters, particularly those influenced by agricultural practices. By utilising a solid carbon ...

In the new cycle of AMPs in the UK, the Environment Agency (EA) is starting to impose total nitrogen limits in accordance with the European Urban Wastewater Directive for nutrient sensitive zones.

After more than a decade of inquiry, a team of scientists has turned the tables on a long-standing controversy to re-establish an old truth about nitrogen mixing in the oceans. After more than a ...
