Influence of shellfish farming activities on nitrification, nitrate reduction to ammonium and denitrification at the water-sediment interface of the Thau lagoon, France [PDF]

open access: yes, 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).

Effectiveness of neem materials and biochar as nitrification inhibitors in reducing nitrate leaching in a compost-amended Ferric Luvisol

open access: yesFrontiers in Soil Science, 2022
The nitrates produced after mineralization from compost may be prone to leaching, especially in tropical sandy soils, because of the increased rate of nitrification and the porous nature of such soils.

Occurrence and abundance of ammonia‐oxidizing archaea and bacteria from the surface to below the water table, in deep soil, and their contributions to nitrification

open access: yesMicrobiologyOpen, 2017
Using molecular biology methods (qualitative and quantitative PCR), we determined the occurrence and abundance of ammonia‐oxidizing archaea (AOA) and ammonia‐oxidizing bacteria (AOB) from a dry inland soil in Basel, Switzerland, and from the riparian ...

Soil aggregate size influences the impact of inorganic nitrogen deposition on soil nitrification in an alpine meadow of the Qinghai–Tibet Plateau [PDF]

open access: yesPeerJ, 2020
Background Ammonium (NH4+) and nitrate (NO3−) are two inorganic forms of nitrogen (N) that are deposited from the atmosphere into soil systems. As the substrate and product of soil nitrification, these two forms of inorganic nitrogen will affect or be ...

Coupling of carbon, nitrogen and oxygen cycles in sediments from a Mediterranean lagoon: a seasonal perspective [PDF]

open access: yes, 2007
Experimental data and simulations were used to investigate the seasonal coupling between carbon, nitrogen and oxygen cycles in marine sediments from a eutrophic shallow lagoon in the Mediterranean Sea area.

Effects of elevated atmospheric carbon dioxide concentration on nitrification of farmland soil

open access: yes浙江大学学报. 农业与生命科学版, 2022
It has been widely reported that elevated carbon dioxide concentration (eCO2) affects soil nitrogen cycling dramatically, in which nitrification plays an important role in net primary productivity and greenhouse gas emission.

Media surface properties and the development of nitrifying biofilms in mixed cultures for wastewater treatment [PDF]

open access: yes, 2013
Plastic was tested to select biofilm support media that would enhance nitrification in the presence of heterotrophs. Eight different types (acrylonitrile butadiene styrene, nylon, polycarbonate, polyethylene, polypropylene, polytetraflouroethylene (PTFE),

Influence of shear on nitrification rates in a membrane bioreactor

open access: yesWater Science and Technology, 2014
Grundfos BioBooster (GBB) installed and operated a membrane bioreactor (MBR) test plant in 2012. During the period it became evident that the nitrification rate was lower than expected and a study was carried out to investigate the possible reasons for the observed low-nitrification rate.

Brachiaria humidicola Cultivation Enhances Soil Nitrous Oxide Emissions from Tropical Grassland by Promoting the Denitrification Potential: A 15N Tracing Study

open access: yesAgriculture, 2022
Biological nitrification inhibition (BNI) in the tropical grass Brachiaria humidicola could reduce net nitrification rates and nitrous oxide (N2O) emissions in soil. To determine the effect on gross nitrogen (N) transformation processes and N2O emissions,
