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 ...

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 ...

Autotrophic Denitrification Processes

2017
Effluents coming from anaerobic digesters are characterized by a COD/N ratio between 2 and 10, high ammonia NH4+ concentrations about 500 mg/L and a temperature range of 25-35 ºC. To remove nitrogen from these effluents biological processes as the autotrophic denitrification with sulfur compounds, hydrogen or methane can be applied.

Denitrification in Rhizobium

Canadian Journal of Microbiology, 1978
Thirty-three strains of Rhizobium were examined for their reduction of nitrate under anoxic conditions. Three patterns of dissimilatory nitrate reduction were observed: (1) reduction to N2O and N2 (denitrification), (2) reduction to and subsequent accumulation of NO2− (nitrate respiration), (3) no reduction. Strains of R.
