DOI: 10.1002/jeq2.20495
Abstract: Denitrification, the anaerobic microbial conversion of nitrate (NO3 - ), a common water pollutant, to nitrogen (N) gases, is often high in the soil of natural wetlands. In areas where natural wetlands have been degraded… read more here.

Regulation of denitrification/ammonia volatilization by periphyton in paddy fields and its promise in rice yield promotion.
Sign Up to like & getrecommendations! Published in 2022 at "Journal of the science of food and agriculture"
DOI: 10.1002/jsfa.12403
Abstract: BACKGROUND Nitrogen (N) is the most limiting nutrient in rice production. N loss via denitrification and ammonia (NH3 ) volatilization decreases N utilization efficiency. The effect of periphyton, which are widespread soil surface microbial aggregates… read more here.

Field-Scale Pattern of Denitrifying Microorganisms and N2O Emission Rates Indicate a High Potential for Complete Denitrification in an Agriculturally Used Organic Soil
Sign Up to like & getrecommendations! Published in 2017 at "Microbial Ecology"
DOI: 10.1007/s00248-017-0991-1
Abstract: More than 50% of all anthropogenic N2O emissions come from the soil. Drained Histosols that are used for agricultural purposes are particularly potent sources of denitrification due to higher stocks of organic matter and fertiliser… read more here.

Hierarchy of factors controls denitrification rates in temperate intermittently closed and open coastal lakes/lagoons (ICOLLS)
Sign Up to like & getrecommendations! Published in 2019 at "Aquatic Ecology"
DOI: 10.1007/s10452-019-09721-4
Abstract: Intermittently closed and open lakes/lagoons (ICOLLs) can occur in alternate stable states: clear and turbid, with nitrogen inputs from high-intensity agricultural land use often fuelling phytoplankton growth in ICOLLs. Due to their limited water exchange,… read more here.

DOI: 10.1007/s10499-019-00402-5
Abstract: This study examined the performance of three independently operated denitrifying moving bed biofilm reactors (MBBRs) in a zero-exchange marine recirculating aquaculture system (RAS) stocked with European seabass (Dicentrarchus labrax). A semi-automated control strategy was applied… read more here.

Contributions of freshwater mussels (Unionidae) to nutrient cycling in an urban river: filtration, recycling, storage, and removal
Sign Up to like & getrecommendations! Published in 2017 at "Biogeochemistry"
DOI: 10.1007/s10533-017-0376-z
Abstract: Consumers contribute to nutrient cycling in aquatic ecosystems by nutrient retention in tissues, metabolic transformations and excretion, and promoting microbial processes that remove nutrients (i.e., nitrogen (N) loss via denitrification). Freshwater mussels (Unionidae) form dense… read more here.

DOI: 10.1007/s11273-020-09741-0
Abstract: Headwater wetlands intercept, store, and transform nitrogen inputs from the landscape. However, uncertainties in rate estimates for processes such as denitrification in surface and subsurface soils hinder our ability to quantitatively predict the downstream water… read more here.
