Biochar Mitigates N2O Emission of Microbial Denitrification through Modulating Carbon Metabolism and Allocation of Reducing Power.

Environmental Science and Technology, 2021
To elucidate the direct effects of biochar on denitrification metabolism at the cellular level, the global response of model denitrifying soil bacterium (Paracoccus denitrificans) to biochar addition was investigated by physiological, proteomic, and ...

Elevated temperature shifts soil N cycling from microbial immobilization to enhanced mineralization, nitrification and denitrification across global terrestrial ecosystems

Global Change Biology, 2020
We assessed the response of soil microbial nitrogen (N) cycling and associated functional genes to elevated temperature at the global scale. A meta‐analysis of 1,270 observations from 134 publications indicated that elevated temperature decreased soil ...

Coupling anammox with heterotrophic denitrification for enhanced nitrogen removal: A review

Critical reviews in environmental science and technology, 2020
Anammox has been recognized as the current most cost-effective nitrogen removal process. However, the issue of excess nitrate residue from its effluent remains to be addressed in order to meet the increasingly stringent discharge standard.

A synergistic partial-denitrification, anammox and in-situ fermentation (SPDAF) process for advanced nitrogen removal from domestic and nitrate-containing wastewater.

Environmental Science and Technology, 2020
This study presents a new method for energy-efficient wastewater treatment that synergizes the partial-denitrification, anammox and in-situ fermentation (SPDAF) processes in an up-flow reactor.

Tailoring the assembly of iron nanoparticles in carbon microspheres toward high performance electrocatalytic denitrification.

Nano letters (Print), 2019
Electrocatalytic denitrification is considered as the most promising technology to transform nitrates to nitrogen gas in sewage so far. Although noble metal-based catalysts as cathode material has reached decent removal capacity of nitrate, the high cost

Achieving Stable Partial Denitrification by Selective Inhibition of Nitrite Reductase with the Biosafe Aprotic Solvent DMSO.

Environmental Science and Technology
The recently proposed partial denitrification (PD), terminating nitrate reduction to nitrite, has been regarded as a promising alternative to nitrite supplying for anammox bacteria.

Denitrification

1999
Abstract Denitrification is the reduction of the nitrogen oxides, nitrate (NO3-) and nitrite (NO2-), to the gases nitric oxide (NO), nitrous oxide (NzO), and dinitrogen (N2). The process is carried out mainly by facultative anaerobes, i.e., organisms that normally use oxygen (02) to accept electrons during respiration but in its absence ...

Soil properties alter plant and microbial communities to modulate denitrification rates in subtropical riparian wetlands

Land Degradation and Development, 2020
The capacity of riparian wetlands to remove nitrogen from upland runoff through the denitrification process is mainly controlled by soil properties and biological communities.

Structural basis of denitrification

Biological Chemistry, 2004
Denitrification represents an important part of the biogeochemical cycle of the essential element nitrogen. It constitutes the predominant pathway of the reductive dissimilation of nitrate in the environment. Via four enzymatic reactions, nitrate is transformed stepwise to nitrite (NO2-), nitric oxide (NO), and nitrous oxide (N2O), to finally yield ...
