The removal of nitrogen (N) in aquatic ecosystems is of great interest because excessive
nitrate in groundwater and surface water is a growing problem. High nitrate loading …

This review summarizes the microbial mechanisms responsible for removal of carbon,
nitrogen, and sulfur compounds in treatment wetlands (TWs) and identifies, categorizes and …

The nitrogen (N) cycle contains two different processes of dissimilatory nitrate (NO 3−)
reduction, denitrification and dissimilatory NO 3− reduction to ammonium (DNRA). While …

Nitrate is generally considered a water pollutant and an undesirable fertilizer residue in the
food chain. Research in the 1970s indicated that, by reducing nitrate to nitrite, commensal …

Nitrification is the microbial conversion of reduced forms of nitrogen (N) to nitrate (NO3−),
and in fertilized soils it can lead to substantial N losses via NO3− leaching or nitrous oxide …

Quantitative PCR of denitrification genes encoding the nitrate, nitrite, and nitrous oxide
reductases was used to study denitrifiers across a glacier foreland. Environmental samples …

Pseudomonas aeruginosa is a ubiquitously distributed opportunistic pathogen that inhabits
soil and water as well as animal-, human-, and plant-host-associated environments. The …

Denitrification, the reduction of nitrate or nitrite to nitrous oxide or dinitrogen, is the major
mechanism by which fixed nitrogen returns to the atmosphere from soil and water. Although …

Nitrate reduction is performed by phylogenetically diverse bacteria. Analysis of narG (alpha
subunit of the membrane bound nitrate reductase) trees constructed using environmental …

Anaerobic ammonium oxidation (anammox) as an important process of nitrogen cycle has
been studied in estuarine environments. However, knowledge about the dynamics of …
