Genetic and environmental controls on nitrous oxide accumulation in lakes. [PDF]
PLoS ONE, 2015 We studied potential links between environmental factors, nitrous oxide (N2O) accumulation, and genetic indicators of nitrite and N2O reducing bacteria in 12 boreal lakes.

La production de nitrites lors de la dénitrification des eaux usées par biofiltration - Stratégie de contrôle et de réduction des concentrations résiduelles [PDF]
Revue des Sciences de l'Eau, 31(1), 2018, 61-73, 2017 The recent popularity of post-denitrification processes in the greater Paris area wastewater treatment plants has caused a resurgence of the presence of nitrite in the Seine river. Controlling the production of nitrite during the post-denitrification has thus become a major technical issue.

Resolution of key roles for the distal pocket histidine in cytochrome C nitrite reductases.
Journal of the American Chemical Society, 2015 Cytochrome c nitrite reductases perform a key step in the biogeochemical N-cycle by catalyzing the six-electron reduction of nitrite to ammonium.

Rhizobium etli Produces Nitrous Oxide by Coupling the Assimilatory and Denitrification Pathways
Frontiers in Microbiology, 2019 More than two-thirds of the powerful greenhouse gas nitrous oxide (N2O) emissions from soils can be attributed to microbial denitrification and nitrification processes.

Nature Communications, 2023 Nitrate ammonification is important for soil nitrogen retention. However, the ecology of ammonifiers and their prevalence compared with denitrifiers, being competitors for nitrate, are overlooked.

Photolysis of n-butyl nitrite and isoamyl nitrite at 355 nm: A time-resolved Fourier transform infrared emission spectroscopy and ab initio study [PDF]
J. Chem. Phys. 130, 174314 (2009), 2009 We report on the photodissociation dynamics study of n-butyl nitrite (n-C_4H_9ONO) and isoamyl nitrite ((CH_3)_2C_3H_5ONO) by means of time-resolved Fourier transform infrared (TR-FTIR) emission spectroscopy. The obtained TR-FTIR emission spectra of the nascent NO fragments produced in the 355-nm laser photolysis of the two alkyl nitrite species showed

Antioxidants and Redox Signaling, 2012 Nitrite, previously considered physiologically irrelevant and a simple end product of endogenous nitric oxide (NO) metabolism, is now envisaged as a reservoir of NO to be activated in response to oxygen (O(2)) depletion. In the first part of this review,

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2022 Background The enterosalivary nitrate–nitrite–nitric oxide (NO3–NO2–NO) pathway generates NO following oral microbiota‐mediated production of salivary nitrite, potentially linking the oral microbiota to reduced cardiometabolic risk.
