Water treatment wetlands are increasingly being used to reduce pollutant loads including nitrogen (N) in urban runoff. Processes such as denitrification (DNF) and anaerobic ammonium oxidation (anammox), which remove N, and dissimilatory nitrate reduc

Understanding the relationship between land use and the dynamics of nitrate (NO3-) is the key to constrain sources of NO3- export in order to aid effective management of waterways. In this study, isotopic compositions of NO3- (δ15N–NO3- and δ18O�

Cable bacteria represent a newly discovered group of filamentous microorganisms, which are capable of spatially separating the oxidative and reductive half-reactions of their sulfide-oxidizing metabolisms over centimeter distances. We investigated th

Estuarine sediments are critical for the remediation of large amounts of anthropogenic nitrogen (N) loading via production of N2 from nitrate by denitrification. However, nitrate is also recycled within sediments by dissimilatory nitrate reduction to

Constructed wetlands are increasingly used within urban areas to reduce pollutant runoff, including nitrogen. These environments are exposed to frequent wetting and drying events, and also increasing temperatures due to the heat island effect and sea
