Ammonia oxidising bacteria (AOB) and archaea are ubiquitous microorganisms, but their abundance and diversity vary widely across environments and play a crucial role in many ecosystems and aquatic ecosystems in particular. However, characterization of AOB communities require genomic methods as they are difficult to isolate from samples.

Ammonia-Oxidizing Bacteria in Wastewater
2011Ammonia-oxidizing bacteria (AOB) have a key role in the conversion of ammonia to nitrite in wastewater treatment plants (WWTPs). The characterization of AOB communities in such systems requires the use of genomic methods as AOB are difficult to isolate from environmental samples.

Bioresource Technology
Ammonia-oxidizing activity of different ammonia-oxidizing microorganisms (AOMs), such as ammonia-oxidizing bacteria (AOB), ammonia-oxidizing archaea (AOA), and complete ammonia oxidizers (comammoxs), were investigated by adding the inhibitors such as 2-phenyl-4,4,5,5-tetramethylimidazoline-1-oxyl 3-oxide, octyne, and KCLO3 in biofilm systems with ...

Ammonia-oxidizing archaea in biological interactions
Journal of Microbiology, 2021The third domain Archaea was known to thrive in extreme or anoxic environments based on cultivation studies. Recent metagenomics-based approaches revealed a widespread abundance of archaea, including ammonia-oxidizing archaea (AOA) of Thaumarchaeota in non-extreme and oxic environments.

Applied and Environmental Microbiology
Nitrification is a key process in the global nitrogen cycle. Aerobic ammonia oxidizers play a central role in the nitrogen cycle by performing the first step of nitrification. Ammonia-oxidizing archaea (AOA) and complete ammonia oxidizers (comammox) are the dominant nitrifiers in environments with low ammonium availability.

Ammonia toxicity and cerebral oxidative metabolism
American Journal of Physiology-Legacy Content, 1961Effects of NH4Cl on oxidative metabolism of cat cerebral cortex slices and mitochondria incubated in vitro were studied. In slices, addition of 10 mm NH4Cl to the incubation medium resulted in significant (16%) reduction of O2 uptake, doubling of lactic acid production and marked increase of glucose utilization compared to control slices.

(Invited) Electrocatalytic Ammonia Oxidation
ECS Meeting Abstracts, 2020Much of the global effort toward producing solar fuels has involved splitting water to obtain molecular hydrogen. Unfortunately, hydrogen gas has a relatively low energy-per-volume, and extreme cryogenic temperature and pressure is needed to bring hydrogen to a condensed state.

Catalytic Oxidation of Ammonia
Russian Chemical Reviews, 1976Data on the catalytic properties of various substances (metals, their alloys, simple and complex oxides, and zeolites containing metal cations) in the oxidation of ammonia are described systematically and reviewed. The kinetics and mechanism of the reaction are discussed and the factors determining the activity and selectivity of the catalysts are ...
