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 ...

The growing abundance of key denitrification genes (napA and narG) in the earlier samples, followed by a decline in the later samples, indicated a dynamic microbial response to the added nitrate. The ...

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 (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 ...

This experiment relies on MIT to explore the optimal operating conditions for embedded immobilized biological fillers under low temperatures, given the aforementioned characteristics of rural ...

(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 ...

Denitrification is a microbial respiratory process in which oxidized nitrogen species, primarily nitrate (NO₃⁻) and nitrite (NO₂⁻), are sequentially reduced to gaseous forms such as nitric oxide (NO), ...
