Denitrification in urban river sediment and the contribution to total nitrogen reduction

Ecological Indicators, 2021
Streams and rivers, especially in urban areas, are substantial sinks of bioavailable nitrogen owing to their hydrological connections with terrestrial systems and the intensity of inputs mediated by human activities.

Low probability of initiating nirS transcription explains observed gas kinetics and growth of bacteria switching from aerobic respiration to denitrification. [PDF]

PLoS Computational Biology, 2014
In response to impending anoxic conditions, denitrifying bacteria sustain respiratory metabolism by producing enzymes for reducing nitrogen oxyanions/-oxides (NOx) to N2 (denitrification).

Denitrification by fungi [PDF]

FEMS Microbiology Letters, 1992
Many fungi in the centre of the group of Fusarium and its teleomorphs were shown to be capable of reducing nitrite anaerobically to form nitric oxide (NO), nitrous oxide (N2O), and/or dinitrogen (N2). Several strains could reduce nitrate as well. Nitrous oxide was the major product of the reduction of nitrate or nitrite.

Denitrification of Permeable Sand Sediment in a Headwater River Is Mainly Influenced by Water Chemistry, Rather Than Sediment Particle Size and Heterogeneity

Microorganisms, 2021
Sediment particle size and heterogeneity play an important role in sediment denitrification through direct and indirect effects on, for example, the material exchange rate, environmental gradients, microbial biomass, and grazing pressure.

Ecological Trait-Based Digital Categorization of Microbial Genomes for Denitrification Potential

Microorganisms
Microorganisms encode proteins that function in the transformations of useful and harmful nitrogenous compounds in the global nitrogen cycle. The major transformations in the nitrogen cycle are nitrogen fixation, nitrification, denitrification, anaerobic

Biological denitrification

Hrvatski časopis za prehrambenu tehnologiju, biotehnologiju i nutricionizam, 2021
Ubrzani napredak industrije, poljoprivrede i domaćinstva su pogodovali povišenim koncentracijama dušika u vodenom ekosustavu, što uzrokuje eutrofikaciju. Dušik se iz otpadne vode uklanja procesom biološke denitrifikacije. U ovom preglednom radu dan je osvrt na denitrifikaciju, s aspekta mikroorganizama, koncentracije otopljenog kisika, donora i ...
