The importance of Dissimilatory Nitrate reduction to ammonium (DNra) in the Nitrogen cycle of coastal ecosystems
Dissimilatory Nitrate Nitrogen cycle
2015/7/16
Until recently, it was believed that biological assimilation and gaseous nitrogen (N) loss through denitrification were the two major fates of nitrate entering or produced within most coastal ecosyste...
Nitrogen fixation and dissimilatory nitrate reduction to ammonium (DNRA) support nitrogen dynamics in Texas estuaries
Nitrogen fi xation dissimilatory nitrate

We conducted continuous-flow experiments on intact sediment cores from Laguna Madre, Sabine Lake, East
Matagorda Bay, and Nueces Estuary to evaluate internal nitrogen (N) sources, sinks, and re...

Nitrogen and oxygen isotope fractionation during dissimilatory nitrate reduction by denitrifying bacteria
Nitrogen and oxygen isotope fractionation dissimilatory nitrate reduction denitrifying bacteria

We report the first measurements of coupled nitrogen (N) and oxygen (O) isotope fractionation of nitrate by laboratory cultures of denitrifying bacteria. Two seawater strains (Pseudomonas stutzeri, Oc...
