Compost and N2O-reducing Microbes as Possible Stabilizers of Biosolids

Eide, Lars Johan (Master thesis, 2021)

Biosolids generated from dewatering the end-product of sludge treatment, digestate, are rich in nitrogen, phosphorous and recalcitrant carbon, and are often utilized as fertilizers/soil conditioners in agriculture. Biosolids ...

Denitrification as an N2O sink

Conthe, Monica; Lycus, Pawel Michal; Arntzen, Magnus Øverlie; da Silva, Aline Ramos; Frostegård, Åsa; Bakken, Lars; Kleerebezem, Robbert; Loosdrecht, Mark C.M. van (Journal article; Peer reviewed, 2018)

The strong greenhouse gas nitrous oxide (N2O) can be emitted from wastewater treatment systems as a byproduct of ammonium oxidation and as the last intermediate in the stepwise reduction of nitrate to N2 by denitrifying ...

Excessive use of nitrogen in Chinese agriculture results in high N2O/(N2O+N2) product ratio of denitrification, primarily due to acidification of the soils

Qu, Zhi; Wang, Jingguo; Almøy, Trygve; Bakken, Lars (Journal article; Peer reviewed, 2014)

High-resolution denitrification kinetics in pasture soils link N2O emissions to PH, and denitrification to c mineralization

Samad, Md Sainur; Bakken, Lars; Nadeem, Shahid; Clough, Timothy J; de Klein, Cecile A M; Richards, Karl G; Lanigan, Gary J; Morales, Sergio E (Journal article; Peer reviewed, 2016)

Higher N2O emission by intensified crop production in South Asia

Raut, Nani; Sitaula, Bishal K.; Bakken, Lars; Bajracharya, Roshan Man; Dörsch, Peter (Journal article; Peer reviewed, 2015)

Intensification of food production in Nepal has been found to acidify the soils and hence increase their apparent propensity to emit N2O as measured by the N2O/(N2+N2O) product ratio of denitrification during standardized ...

Impaired Reduction of N2O to N2 in Acid Soils Is Due to a Posttranscriptional Interference with the Expression of nosZ

Liu, Binbin; Frostegård, Åsa; Bakken, Lars (Journal article; Peer reviewed, 2014)

Accumulating empirical evidence over the last 60 years has shown that the reduction of N2O toN2 is impaired by low soil pH, suggesting that liming of acid soils may reduce N2O emissions. This option has not gained much ...

Kinetics of NH3-oxidation, NO-turnover, N2O-production and electron flow during oxygen depletion in model bacterial and archaeal ammonia oxidisers

Hink, Linda; Lycus, Pawel Michal; Gubry-Rangin, Cecile; Frostegård, Åsa; Nicol, Graeme W.; Prosser, James I.; Bakken, Lars (Journal article; Peer reviewed, 2017)

Ammonia oxidising bacteria (AOB) are thought to emit more nitrous oxide (N2O) than ammonia oxidising archaea (AOA), due to their higher N2O yield under oxic conditions and denitrification in response to oxygen (O2) limitation. ...

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

Measuring growth of denitrifiers in digestate using gas kinetics

Jakobsen, Stine Johanne Heffermehl (Master thesis, 2018)

Denitrification is a microbial, anaerobic process reducing nitrogen oxyanions to gaseous products in a stepwise reaction that leads to a release of nitrous oxide gas to the atmosphere. Denitrification has four steps; NO3 ...

Microbes meet real-life : understanding how denitrifying bacteria handle nutrient limitation : a prerequisite for novel N2O mitigation options

Simonsen, Silje Kvist (Master thesis, 2021)

Dinitrogenoksid (N2O) er den tredje viktigaste klimagassen etter CO2 og metan, og er ein viktig bidragsyter til øydelegginga av ozonlaget. Globale N2O-utslipp er aukande, og mesteparten av utsleppa som er knytt til menneskeleg ...

Modeling organic matter decomposition and nitrogen dynamics in agricultural soils : Environmental impacts of plant production systems
