Production of NO2- and N2O by Nitrifying Bacteria at Reduced Concentrations of Oxygen
Thomas J. Goreau,Warren A. Kaplan,Steven C. Wofsy,Michael B. McElroy,Frederica W. Valois,Stanley W. Watson +5 more
TL;DR: The results support the view that nitrification is an important source of N(2)O in the environment and that nitrite-oxidizing bacteria (Nitrobacter sp.) and the dinoflagellate Exuviaella sp.
Journal ArticleDOI
Nitrification, denitrification and nitrous oxide cycling in the eastern tropical South Pacific ocean
L.A Codispoti,J.P Christensen +1 more
TL;DR: In this paper, the authors suggest a total denitrification rate of ∼ 60 Tg N y−1 for the marine water column, while estimates for the combined nitrogen inputs into the sea via the atmosphere and marine nitrogen fixation have decreased.
Journal ArticleDOI
Nitrification at low levels of dissolved oxygen with and without organic loading in a suspended-growth reactor.
TL;DR: In this article, a mixed-flow RL with DO (dissolved oxygen) control was operated at 25°C using substrate containing 80 mg l−1 of NH3-N. Determination of the biomass index based on the substrate utilization rate revealed that low levels of DO elevated the growth yield of ammonia oxidizers by double.

Oxygen Sensitivity of Anammox and Coupled N-Cycle Processes in Oxygen Minimum Zones
Tim Kalvelage,Marlene Mark Jensen,Sergio Contreras,Niels Peter Revsbech,Phyllis Lam,Marcel Günter,Julie LaRoche,Gaute Lavik,Marcel M. M. Kuypers +8 more
TL;DR: This study provides the first robust estimates of O2 sensitivities for processes directly and indirectly connected with N-loss, and shows that aerobic and anaerobic N-cycle pathways in OMZs can co-occur over a larger range of O1 concentrations than previously assumed.

Denitrification in the oxygen minimum layer of the eastern tropical Pacific Ocean
TL;DR: Molecular nitrogen and nitrite are produced concurrently from nitrate-15N added to the oxygen-deficient and Nitrite-rich water below the thermocline in the tropical eastern Pacific Ocean as mentioned in this paper.
Journal ArticleDOI
On denitrification in the northeastern tropical Pacific Ocean
TL;DR: The existence of a maximum in nitrite concentration in the oxygen minimum layer below the thermocline in the northeastern tropical Pacific Ocean has been confirmed as mentioned in this paper, and it is suggested that further denitrification to N 2 O or N 2 had occurred.

Nitrate Reduction in Seawater of the Deep Nitrite Maximum off PERU1
A. F. Carlucci,Hazel R. Schubert +1 more
TL;DR: In this paper, Nitrate-reducing bacteria were isolated from samples collected inside and outside the secondary nitrite maximum in oxygen-poor deep waters off the coast of Peru and showed that these bacteria reduced nitrate to nitrite in seawater enriched with 0.5 to 1.0 mg glucose/liter.
