Diversity and spatial distribution of hydrazine oxidoreductase (hzo) gene in the oxygen minimum zone off Costa Rica. [PDF]

PLoS ONE, 2013
Anaerobic ammonia oxidation (anammox) as an important nitrogen loss pathway has been reported in marine oxygen minimum zones (OMZs), but the community composition and spatial distribution of anammox bacteria in the eastern tropical North Pacific (ETNP ...

Catalysts for Electrochemical Oxidation of Ammonia: A Comprehensive Review of Fundamentals and Optimization Strategies

Advanced Materials, Volume 38, Issue 4, 16 January 2026.
Developing robust catalysts for ammonia electrochemical oxidation (AOR) is essential for advancing NH3 utilization technologies. This review summarizes recent progress in catalyst design and mechanistic understanding of AOR. In addition, it systematically investigates strategies to improve AOR performance for various types of catalysts.

Effect of Nitric Oxide on Anammox Bacteria [PDF]

Applied and Environmental Microbiology, 2010
ABSTRACT The effects of nitrogen oxides on anammox bacteria are not well known. Therefore, anammox bacteria were exposed to 3,500 ppm nitric oxide (NO) in the gas phase. The anammox bacteria were not inhibited by the high NO concentration but rather used it to oxidize additional ammonium to dinitrogen gas under conditions relevant to ...

Isotopic constraints on active nitrification in a eutrophic artificially oxygenated lake: Implications for nitrate regeneration and nitrous oxide production

Limnology and Oceanography, Volume 71, Issue 1, January 2026.
Abstract Nitrification is a key process in the aquatic nitrogen (N) cycle, but its products, nitrate (NO3−) and nitrous oxide (N2O), contribute to eutrophication and greenhouse gas emissions, particularly in eutrophic lakes. Variations in in‐lake N cycling and N2O production pathways, as a function of seasonality and artificial oxygenation, remain ...

Microbial nitrogen removal and recycling in the redox transition zone of a meromictic lake and its coupling to sulfur cycling

Limnology and Oceanography, Volume 71, Issue 1, January 2026.
Abstract Organotrophic denitrification is an important nitrogen (N) removal process in lakes, but alternative N reduction processes such as lithotrophic sulfur (S)‐oxidizing denitrification may be greatly underappreciated. We studied the redox transition zone (RTZ) in the meromictic water column of the North Basin of Lake Lugano (Switzerland) to ...

Fate of dissolved organic nitrogen during the Anammox process using ultra-high resolution mass spectrometry

Environment International, 2019
Anaerobic ammonium oxidation (Anammox) is a cost-effective process for treating highly nitrogenous wastewater. However, the fate of organic nitrogen during Anammox treatment is still unclear, which limits its practical application.

ANAEROBİK AMONYUM OKSİDASYONU (ANAMMOX)

Uludağ University Journal of The Faculty of Engineering, 2019
The nitrogen element, which constitutes 75.5% by weight and 78.06% by volume of the Earth's atmosphere, participates in the structure of many important biomolecules such as ATP, chlorophyll, nucleic acids and vitamins. However, this element found as a form of dinitrogen gas (N2) is not suitable form to use for living organisms, especially primary ...

Nitric oxide supersaturation in the surface waters of the oligotrophic Atlantic Ocean

Limnology and Oceanography Letters, Volume 11, Issue 1, January 2026.
Abstract Atmospheric nitric oxide (NO) is a pollutant and climate‐relevant trace gas. Dissolved NO accumulates in the surface ocean and therefore the ocean is a natural source of atmospheric NO. It is generally assumed that NO in the surface ocean is produced photochemically from nitrite (NO2−).
