Effects of relic low-head dams on stream denitrification potential: seasonality and biogeochemical controls
The majority of dams in the contiguous United States are small, low-head dams that are no longer operational but can influence the water quality of...

Nitrogen availability and denitrification in urban agriculture and regreened vacant lots
Many cities demolish abandoned homes and create regreened vacant lots (RVLs), and an increasingly popular, high-intensity use of RVLs is as urban...

The anaerobic soil volume as a controlling factor of denitrification: a review
Denitrification is an important component of the nitrogen cycle in soil, returning reactive nitrogen to the atmosphere. Denitrification activity is...

Saltwater incursion regulates N2O emission pathways and potential nitrification and denitrification in intertidal wetland
Variations of N transformation processes, N 2 O release rates, and N 2 O emission pathways were investigated at different levels of salinity (stage 1,...

Advance in the sulfur-based electron donor autotrophic denitrification for nitrate nitrogen removal from wastewater
In the field of wastewater treatment, nitrate nitrogen (NO 3 − -N) is one of the significant contaminants of concern. Sulfur autotrophic denitrification...

Genetic variation in Zea mays influences microbial nitrification and denitrification in conventional agroecosystems
Background and AimsNitrogenous fertilizers provide a short-lived benefit to crops in agroecosystems, but stimulate nitrification and denitrification,...

Partitioning of the denitrification pathway and other nitrite metabolisms within global oxygen deficient zones
Oxygen deficient zones (ODZs) account for about 30% of total oceanic fixed nitrogen loss via processes including denitrification, a microbially...

Long-Term Pollution Does Not Inhibit Denitrification and DNRA by Adapted Benthic Microbial Communities
Denitrification in sediments is a key microbial process that removes excess fixed nitrogen, while dissimilatory nitrate reduction to ammonium (DNRA)...

Comparative genomic analysis of two Arctic Pseudomonas strains reveals insights into the aerobic denitrification in cold environments
BackgroundBiological denitrification has been commonly adopted for the removal of nitrogen from sewage effluents. However, due to the low temperature...

The potential importance of soil denitrification as a major N loss pathway in intensive greenhouse vegetable production systems
BackgroundAbout 30 % of vegetables in China are produced in intensively managed greenhouses comprising flood irrigation and extreme rates of nitrogen...

Aerobic bacteria produce nitric oxide via denitrification and promote algal population collapse
Microbial interactions govern marine biogeochemistry. These interactions are generally considered to rely on exchange of organic molecules. Here we...

Denitrification is not Necessarily the Main Source of N2O from Rewetted Fens
Drained agricultural peatlands are being increasingly rewetted for global warming mitigation. This creates novel ecosystems, with unclear effects on...

Loading of redox-active metal Fe largely enhances the capacity of biochar to mitigate soil N2O emissions by promoting complete denitrification
Nitrous oxide (N 2 O) is a critical greenhouse gas and an ozone-depleting substance, with a global warming potential 298–310 times greater than that of...

Dry season residual straw reduces nitrous oxide emissions during rice season in upland-paddy rotation systems by inhibiting soil denitrification
The mechanism by which residual straw incorporation affects nitrous oxide (N 2 O) and carbon dioxide equivalent (CO 2 -eq) emissions throughout the rice...
-
Changes in soil pore structure generated by the root systems of maize, sorghum and switchgrass affect in situ N2O emissions and bacterial denitrification
Due to the heterogeneous nature of soil pore structure, processes such as nitrification and denitrification can occur simultaneously at microscopic...

Hybrid pathways of denitrification drive N2O but not N2 emissions from an acid-sulphate sugarcane soil
Acid-sulphate sugarcane soils in the subtropics are known hot-spots for nitrous oxide (N 2 O) emissions, yet the reduction of reactive N 2 O to...
