Detection and Quantification of Nitrifying Bacteria Using Real-Time PCR
(2020-01-01)
Nitrification is the microbial-mediated transformation of ammonium (NH4 +) into nitrate (NO3 −). Many plant species depend on the availability of NO3 − as the main source of nitrogen (N). On the other hand, because NO3 − ...
Nitrification inhibition in tropical soil under no tillage system
(2014)
In no-tillage systems (NTS), biological activity and nitrification process in the soil are higher due to higher organic matter and moisture contents, resulting in higher levels of nitrate compared with areas under conventional ...
Elevation and vegetation influences on soil properties in Chilean Nothofagus forests
(Sociedad de Biología de Chile, 2003)
Nitrification and ammonia-oxidizing bacteria shift in response to soil moisture and plant litter quality in arid soils from the Patagonian Monte
(Elsevier Gmbh, 2016-01)
We aimed to evaluate the effects of both plant litter quality, characteristic of sites with different histories of grazing disturbance, and soil water content on nitrification in soils from an arid ecosystem of Patagonia. ...
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 ...
The use of a flocculant additive and its effect on biofloc formation, nitrification, and zootechnical performance during the culture of Pacific white shrimp Penaeus vannamei (Boone, 1931) in a BFT system
