“…Although NO is an obligatory intermediate of denitrification, NO emission from anaerobic soil can't be observed due to its fast reduction or slow diffusion under the anaerobic condition (Russow et al, 2008). Both NO and N 2 O can be produced as by-products in nitrification process (Remde and Conrad, 1990). Many lab and field experiments suggest that NO released from soils is mainly produced through the nitrification of NH 4 + while denitrification is the major source of N 2 O under most situations (Davidson et al, 1993;Hutchinson et al, 1993;Parsons and Keller, 1995;Skiba et al, 1997;Gödde and Conrad, 2000;Dobbie and Smith, 2001;Azam et al, 2002;Russow et al, 2008;Vilain et al, 2014).…”

“…Remde and Conrad [1990] and Anderson et al [1993] showed that N 2 O and NO are produced by reduction of NO 2 À rather than as intermediates in the oxidation of either NH 4 + or NH 2 OH, a process referred to as aerobic denitrification (or nitrifier denitrification) [Colliver and Stephenson, 2000;Wrage et al, 2001].

“…Bock et al [1995] [Goreau et al, 1980;Lipschultz et al, 1981]. The ratio of NO to N 2 O (mole N/mole N) is typically greater than 1 for aerobic denitrification and increases with decreasing levels of O 2 , ranging from 1.15 to as high as 100 [Lipschultz et al, 1981;Remde and Conrad, 1990;Anderson and Levine, 1986;Kester et al, 1997].…”

[1] More than 220 Tg N are processed annually through the global agriculture/animal/ human food chain. It is suggested that aerobic denitrification, reduction of nitrite formed in the first stage of nitrification, is an important source not only of global N 2 O but also of NO x . A simple top-down method indicates a globally averaged yield of 2% for N 2 O emitted as a consequence of human disturbances to the global nitrogen cycle. This yield can account not only for the contemporary budget of atmospheric N 2 O but also for trends observed over the past 1000 years. The associated microbial source of NO x is estimated assuming a NO x /N 2 O ratio of 3, consistent with results from a variety of laboratory and field studies. This source is significant, particularly for large developing countries such as China and India for which its contribution is comparable to that from fossil fuel.

“…These gaseous nitrogen oxides are produced by a mechanism that is reminiscent of the production of NO and N 2 O by organisms from the group of heterotrophic denitrifying bacteria (15,16). Denitrification is an anaerobic mode of respiration that involves the enzymes nitrate reductase, nitrite reductase (Nir), nitric oxide reductase, and nitrous oxide reductase, which catalyze the stepwise reduction of nitrate (NO 3 Ϫ ), via the intermediates nitrite (NO 2 Ϫ ), NO, and N 2 O, to dinitrogen (24).…”

Nitrosomonas europaea Expresses a Nitric Oxide Reductase during Nitrification

et al. 2004

In this paper, we report the identification of a norCBQD gene cluster that encodes a functional nitric oxide reductase (Nor) in Nitrosomonas europaea. Disruption of the norB gene resulted in a strongly diminished nitric oxide (NO) consumption by cells and membrane protein fractions, which was restored by the introduction of an intact norCBQD gene cluster in trans. NorB-deficient cells produced amounts of nitrous oxide (N 2 O) equal to that of wild-type cells. NorCB-dependent activity was present during aerobic growth and was not affected by the inactivation of the putative fnr gene. The findings demonstrate the presence of an alternative site of N 2 O production in N. europaea.
