Denitrification potential of riparian sediments amended with

Journal of Ecology and Environment, 2014
Denitrification permanently removes nitrate from aquatic ecosystems, so construction of denitrification walls to enhance denitrification activity is often suggested to reduce the nitrate levels from tributary ecosystems.

Waterbird zoogeochemical effects shape wetland nutrient dynamics and algal communities in Laurentian Great Lakes coastal freshwater wetlands

Journal of Animal Ecology, EarlyView.
Distinct waterbird species influence nutrient cycling through guano contributions in Great Lakes coastal wetlands. Waterbird‐derived nutrients favour distinct algal communities and wetland sediments rapidly remove waterbird nutrients via biogeochemical processes.

Metabolic coupling between soil aerobic methanotrophs and denitrifiers in rice paddy fields

Nature Communications
Paddy fields are hotspots of microbial denitrification, which is typically linked to the oxidation of electron donors such as methane (CH4) under anoxic and hypoxic conditions.

Spatial Patterns of Avian Stable Isotopes Reveal Ecological Impacts of Climate and Land‐Use Change

Integrative Zoology, EarlyView.
Increased feather δ15N values with pasture coverage reveal an elevated baseline δ15N in grazing landscapes, while broader isotopic niches in farmland habitats reflect agricultural expansion's significant influence on resource use patterns of the avian community.

Innovative Field Applications of Probiotics, Prebiotics, and Medicinal Plant Products for Disease Control in Aquaculture

Journal of Fish Diseases, EarlyView.
ABSTRACT Disease outbreaks and the associated reliance on antibiotics pose major constraints to the sustainability of modern aquaculture. As regulatory pressures increase and consumer demand shifts toward residue‐free production, diverse biological interventions are gaining prominence as viable alternatives to chemotherapeutics.

Isolation, identification, and the denitrification characteristics for a denitrifying strain: Paracoccus huijuniae

上海师范大学学报. 自然科学版
Nitrogen(N) removal become an important topic in municipal wastewater treatment, in which denitrification seems more important step. A denitrifying strain, Paracoccus huijuniae, was isolated and was employed for accelerating denitrification by means of ...

Insights into plant‐part‐specific N2O production in roots and shoots of chicory (Cichorium intybus) using stable isotope labelling

New Phytologist, EarlyView.
Conceptual scheme of the nitrous oxide (N2O) production, consumption, and transport processes across the soil–plant–atmosphere continuum. Summary Nitrous oxide (N2O) contributes substantially to climate change and stratospheric ozone degradation, yet large uncertainties in its global budget point to overlooked sources.

Denitrification in soil. II. Factors affecting denitrification

The Journal of Agricultural Science, 1958
1. The factors affecting denitrification in soil have been studied by determining loss of nitrogen from soil under various conditions by total-N analysis.2. It was found that the rate of denitrification of nitrate in soil was dependent upon various factors such as the pH, temperature and water content of the soil and that, under conditions conducive to

The ComEA/ComEC Operon is Critical for Nitrosative Stress Tolerance by an Oral Commensal

Molecular Oral Microbiology, EarlyView.
ABSTRACT Oral commensal streptococci play a large role in mediating microbial homeostasis. Our prior work has demonstrated that hydrogen peroxide (H2O2) produced by oral commensal streptococci can react with salivary nitrite (NO2) and generate peroxynitrite (ONOO−), a potent antimicrobial.

Optimization of Reaction Kinetic Model for Polymer Catalytic Reduction Denitrification

Journal of Chemistry
Polymer catalytic reduction (PCR) is a denitrification method that may exhibit higher efficiency and lower cost. However, the presence of catalysts in the PCR agent adds complexity to the denitrification reaction kinetics.
