Denitrification is important in that it removes fixed nitrogen (i.e., nitrate) from the ecosystem and returns it to the atmosphere in a biologically inert form (N 2).

Here we show that the direct, anaerobic oxidation of methane coupled to denitrification of nitrate is possible. A microbial consortium, ...

Denitrification, Its Importance Once Diluted, May Be Back On Top Date: September 4, 2009 ... which they called anaerobic oxidation or "anammox" and that involved different bacteria, ...

However, their effects are dramatic: "Our estimates based on model simulations show that anaerobic denitrification in these anoxic pockets can account for up to one-third of the total ...

Denitrification, its importance once diluted, may be back on top, Princeton-led team says Peer-Reviewed Publication. Princeton University. image ... In low-oxygen -- or anaerobic ...

Limnology and Oceanography, Vol. 58, No. 1 (2013), pp. 1-12 (12 pages) In addition to organotrophic denitrification, alternative pathways, such as anaerobic ammonium oxidation (anammox) or ...

This study offers new evidence of nitrite-driven anaerobic ethane oxidation occurring in enriched cultures from hot-spring sediment, and describes a novel genus potentially involved in this process.

In low-oxygen -- or anaerobic -- conditions seen in large stretches of ocean sediments and in a few important regions of the open ocean, ... "If denitrification is important in the Arabian Sea, then ...

However, their effects are dramatic: "Our estimates based on model simulations show that anaerobic denitrification in these anoxic pockets can account for up to one third of the total ...

• Tiny environments: Microorganisms on sand grains create anoxic microenvironments. • Big impact: This allows their neighbours to carry out anaerobic denitrification in well-oxygenated sands ...
