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 ...

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 ...

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.

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 ...

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

Corn bred with genes from wild relatives can reshape soil microbial communities and reduce nitrogen loss — with no yield reduction — ...

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.

Septic tanks are the second largest source of groundwater nitrate contamination. In this study, the feasibility of coupling a conventional lateral field with a sulfur-limestone (S/L) layer to treat ...

Denitrification (the process by which nitrate and nitrite are reduced to nitrogen gas) in the oxygen-minimum zones of modern oceans is an important part of the global nitrogen cycle. Variations in ...

(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 ...
