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

As ice sheets melted during the deglaciation of the last ice age and global oceans warmed, oceanic oxygen levels decreased and "denitrification" accelerated by 30 to 120 percent, a new international ...

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 ...

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

Underground environments like soil and aquifers teem with microbial life. These tiny microbes play a big role in cycling nutrients and breaking down or transforming pollutants. However, scientists ...

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.

(a) Illustration of glucose metabolism. FADH 2: flavin adenine dinucleotide (reduced form), FAD: flavin adenine dinucleotide, ATP: adenosine triphosphate, ADP: adenosine diphosphate; (b, c) KEGG ...

Fungal denitrification play a key role in the regulation of nitrogen cycle. Knowledge of the fungal denitrification of soil microbes and the driving mechanisms will be essential to understand the ...
