Electrodes donate electrons for nitrate reduction in a soil matrix via DNRA and denitrification
(American Chemical Society, 2019-02-19)
Microbial strains and indigenous microbiota in soil slurries have been reported to use electrons from electrodes for nitrate (NO₃⁻) reduction. However, few studies have confirmed this in a soil matrix hitherto. This study ...
Effects of nitrate and water content on acetylene inhibition technique bias when analysing soil denitrification rates under an aerobic atmosphere
The acetylene inhibition technique (AIT) is the most widely used indirect method of determining denitrification fluxes. Although AIT bias has long been recognised, the contributions of soil denitrification-related parameters ...
Biochar's role as an electron shuttle for mediating soil N₂O emissions
The functionality of biochar as an electron shuttle has been hypothesized to rationalize its suppressing effect on nitrous oxide (N₂O) emissions from soil denitrification. However, this hypothesis has not yet been ...
Rice root Fe plaque enhances paddy soil N₂O emissions via Fe(II) oxidation-coupled denitrification
Iron (Fe) plaque, defined as a film of poorly crystalline Fe oxides deposited on the surface of rice roots, potentially mediates paddy-soil N₂O emissions. The aims of this study were to test if, and how, Fe plaque affects ...
Perturbation-free measurement of in situ di-nitrogen emissions from denitrification in nitrate-rich aquatic ecosystems
(Elsevier on behalf of IWA Publishing, 2017-02-01)
Increased production of reactive nitrogen (Nr) from atmospheric di-nitrogen (N₂) has greatly contributed to increased food production. However, enriching the biosphere with Nr has also caused a series of negative effects ...
N₂ production via aerobic pathways may play a significant role in nitrogen cycling in upland soils
The importance of di-nitrogen (N₂) production via aerobic pathways has been verified in a significant number of pure microbial strains. However, to date there are no reports confirming this in situ. In this study, we ...
