Modelling the inorganic nitrogen behaviour in a small Mediterranean forested catchment, Fuirosos (Catalonia) [PDF]
, 2010 The aim of this work was to couple a nitrogen (N) sub-model to already existent hydrological lumped (LU4-N) and semi-distributed (LU4-R-N and SD4-R-N) conceptual models, to improve our understanding of the factors and processes controlling nitrogen ...

Development of N2O emission factors derived from nitrification of treated sewage water in rivers
Water Science and Technology, 2023 Because treated sewage water contains nitrogen compounds such as NH4-N and NO2+3-N, nitrous oxide (N2O) which is one of the greenhouse gases is generated by nitrification and denitrification reactions in rivers.

Effect of influent nutrient ratios and hydraulic retention time (HRT) on simultaneous phosphorus and nitrogen removal in a two-sludge sequencing batch reactor process [PDF]
, 2009 A laboratory-scale anaerobic–anoxic/nitrification sequencing batch reactor (A2N- SBR) fed with domestic wastewater was operated to examine the effect of varying ratios of influent COD/P, COD/TN and TN/P on the nutrient removal.

It Takes a Village: Discovering and Isolating the Nitrifiers
Frontiers in Microbiology, 2020 It has been almost 150 years since Jean-Jacques Schloesing and Achille Müntz discovered that the process of nitrification, the oxidation of ammonium to nitrate, is a biological process carried out by microorganisms.

Coupled anoxic nitrification/manganese reduction in marine sediments [PDF]
, 1999 Pore water and solid phase distributions of oxygen, manganese, and nitrogen from hemipelagic and shelf sediments sometimes indicate a close coupling between the manganese and nitrogen redox cycles.

High-throughput assays to identify archaea-targeting nitrification inhibitors
Frontiers in Plant ScienceNitrification is a microbial process that converts ammonia (NH3) to nitrite (NO2-) and then to nitrate (NO3-). The first and rate-limiting step in nitrification is ammonia oxidation, which is conducted by both bacteria and archaea.

Ammonium uptake by phytoplankton regulates nitrification in the sunlit ocean. [PDF]
PLoS ONE, 2014 Nitrification, the microbial oxidation of ammonium to nitrate, is a central part of the nitrogen cycle. In the ocean's surface layer, the process alters the distribution of inorganic nitrogen species available to phytoplankton and produces nitrous oxide.

Influence of shellfish farming activities on nitrification, nitrate reduction to ammonium and denitrification at the water-sediment interface of the Thau lagoon, France [PDF]
, 1997 The seasonal patterns of nitrification, denitrification and dissimilatory ammonium production (DAP) rates were studied in the sediment of 2 stations in the Thau lagoon (south of France).

Effect of Influent COD/N Ratio on Nitrification Rate in a Bench-scale Biological Reactor [PDF]
آب و فاضلاب, 2005 Nitrification, the oxidation of ammonia to nitrate catalyzed by bacteria, is a key part of the global nitrogen cycle. In the first step of nitrification, chemolithoautotrophic ammonia oxidizers transform ammonia to nitrite, which subsequently oxidizes to

Microorganisms, 2019 Ammonia oxidizing archaea (AOA) and bacteria (AOB) are thought to contribute differently to soil nitrification, yet the extent to which their relative abundances influence the temperature response of nitrification is poorly understood.
