The influence of soil properties on denitrifying bacterial communities and denitrification potential in no-till production farms under contrasting management in the Argentinean Pampas
(Elsevier, 2013-12)
The aim of this work was to investigate the response of the structure, abundance and potential activity of denitrifiers to contrasting agricultural management in no-till production fields, across a regional scale within ...
Simultaneous heterotrophic nitrification and aerobic denitrification of wastewater in granular reactor: Microbial composition by next generation sequencing analysis
(Elsevier Ltd, 2020-08)
Dairy effluents contain limited nitrogen for biological treatment. In the present study a cheese whey wastewaterwas supplemented with ammonia to obtain suitable COD:N ratios. The effects of the organic load and micronutrientson ...
Water table effects on bean yield and nitrate distribution in the soil profile
(2008-07-01)
In order to evaluate the bean yield under different water table levels as well as the moisture and nitrate distribution in the soil profile, a field experiment was carried out in the experimental area of the College of ...

Contrasting Effects of Nitrogen and Labile Carbon Addition on N2O Emissions from Andosols in Costa Rica and Chile Under Controlled Conditions
(2022-07-20)
Our study analyzes nitrous oxide (N2O) emissions of two volcanic soils, from a tropical (Costa Rica) and temperate (Chile) environment. Volcanic origin soils are important for dairy production in both countries and ...
Feasibility of a Sequencing Reactor Operated in Batch and Fed-batch Mode Applied to Nitrification and Denitrification Processes
(ASOC QUIMICOS, 2009)
The objective of this work was to study the operational feasibility of nitrification and denitrification processes in a mechanically stirred sequencing batch reactor (SBR) operated in batch and fed-batch mode. The reactor ...
ZrO2-modified Al2O3-supported PdCu catalysts for the water denitrification reaction
(Elsevier, 2014-03-12)
Monometallic Pd and bimetallic Pd?Cu catalysts supported on alumina, zirconia and ZrO2?Al2O3 mixed oxides of different composition were prepared and evaluated in the catalytic denitrification of water. The supports were ...
A Two-Stage Aerobic/Anaerobic Denitrifying Horizontal Bioreactor Designed for Treating Ammonium and H2S Simultaneously
(HUMANA PRESS INCTOTOWA, 2012)
A two-stage bioreactor was operated for a period of 140 days in order to develop a post-treatment process based on anaerobic bioxidation of sulfite. This process was designed for simultaneously treating the effluent and ...
Structural aspects of PtSn/g-Al2O3 catalysts prepared through surface controlled reactions. Behavior in the water denitrification reaction
(Elsevier, 2013-01-04)
This research focuses on the controlled preparation and characterization of PtSn/-Al2O3 catalysts and their activity and selectivity in water denitrification by reduction of NO3 − and NO2 − ions with hydrogen. The bimetallic ...
