Nitrate (NO3−) concentrations in public water supplies have risen above acceptable levels
in many areas of the world, largely as a result of overuse of fertilizers and contamination by …

The effects of increased nitrogen loading on denitrification and dissimilatory nitrate reduction
to ammonium (DNRA) in marsh sediments were studied in permanently submerged subtidal …

Earlier observations in mangrove sediments of Goa, India have shown denitrification to be a
major pathway for N loss. However, percentage of total nitrate transformed through complete …

Assessing nitrogen dynamics in the estuarine landscape is challenging given the unique
effects of individual habitats on nitrogen dynamics. We measured net N 2 fluxes, sediment …

Primarily because of their high levels of microbiological activity, wetland soils play a key role
in ameliorating nitrogen pollution and reducing nutrient loadings to coastal zones. Saltwater …

In this study, basic sediment properties, nutrient flux, and nitrogen cycle (including
denitrification, anaerobic ammonium oxidation [anammox], nitrification, and dissimilatory …

Purpose Denitrification has been extensively studied in soils from temperate zones in
industrialized countries. However, few studies quantifying denitrification rates in soils from …

Nutrient budgets in semi-arid estuaries, with ephemeral freshwater inflows and limited
nutrient sources, are likely incomplete if contributions from submarine groundwater …

Vegetation alteration and nitrogen inputs (via run-off, atmospheric deposition, and
wastewater) as a result of anthropogenic activities strongly affected the emission of N 2 O …

Dissimilatory nitrate reduction to ammonium (DNRA) is an important process of nitrate
reduction in the environment. The distribution of DNRA bacteria and the relationships with …
