Effect of Influent COD/N Ratio on Nitrification Rate in a Bench-scale Biological Reactor [PDF]
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

High nitrification rate with upflow biofiltration
In order to investigate the upper limit of aerated biofilm processes, a series of experiments has been carried out on a pilot scale with a synthetic effluent containing only ammonium nitrogen and inorganic carbon as substrates.

Soil Nitrification Rate Is Affected by Plant Species and Nitrogen Levels
The soil nitrification rate is significantly affected by plant species, and it is also modulated by different nitrogen levels in the soil. There are a wide range of plant species with the capacity to produce biological nitrification inhibitors (hereafter

Assesment of nitrification and denitrification rate in biological nitrogen removal from wastewater
Biological nitrogen removal from wastewater is based on nitrification and denitrification processes in biological treatment plants with activated sludge. Slowed growth of nitrification bacteria is one of basic problems in biological nitrogen removal from

Relative efficacy and stability of biological and synthetic nitrification inhibitors in a highly nitrifying soil: Evidence of apparent nitrification inhibition by linoleic acid and linolenic acid [PDF]
Biological nitrification inhibition is a plant‐mediated rhizosphere process where natural nitrification inhibitors can be produced and released by roots to suppress nitrifier activity in soil.

A comparison of two nitrification inhibitors used to measure nitrification rates in estuarine sediments [PDF]
Abstract Nitrification rates were measured using intact sediment cores from South San Francisco Bay and two different nitrification inhibitors: acetylene and methyl fluoride. Sediment oxygen consumption and ammonium and nitrate fluxes were also measured in these cores. Four experiments were conducted in the spring, and one in the fall of 1993.

Increasing livestock wastewater application in alternate-furrow irrigation reduces nitrification gene abundance but not nitrification rate in rhizosphere [PDF]
Wastewater generated during livestock production is rich in nitrogen, but careless discharge could result in greenhouse gas emission, eutrophication or other problems.

Nitrification rates in the NW Mediterranean Sea [PDF]
During spring, ammonium oxidation and nitrite oxidation rates were measured in the NW basin of the Mediterranean Sea, from mesotrophic sites (Ligunan Sea and Gulf of Lions) to oligotrophc sites (Balearic Islands). Nitrification rates (average values for 37 measurements) ranged from 72 to 144 nmol of N oxidised 1-' d-', except in the RhBne River plume ...
