Ammonia-oxidizing archaea have more important role than ammonia-oxidizing bacteria in ammonia oxidation of strongly acidic soils [PDF]
ISME Journal, 2011 Abstract Increasing evidence demonstrated the involvement of ammonia-oxidizing archaea (AOA) in the global nitrogen cycle, but the relative contributions of AOA and ammonia-oxidizing bacteria (AOB) to ammonia oxidation are still in debate. Previous studies suggest that AOA would be more adapted to ammonia-limited oligotrophic conditions,

Biodegradation potential of wastewater micropollutants by ammonia-oxidizing bacteria
Chemosphere, 2009This study examined the biodegradation potential of three wastewater micropollutants (triclosan, bisphenol A, and ibuprofen) by Nitrosomonas europaea and mixed ammonia-oxidizing bacteria in nitrifying activated sludge. N. europaea could degrade triclosan and bisphenol A, but not ibuprofen.

Impact of acetochlor on ammonia-oxidizing bacteria in microcosm soils
Journal of Environmental Sciences, 2008Acetochlor is an increasingly used herbicide on corn in North China. Currently, the effect of acetochlor on soil ammonia-oxidizing bacteria (AOB) communities is not well documented. Here, we studied the diversity and community composition of AOB in soil amended with three concentrations of acetochlor (50, 150, 250 mg/kg) and the control (0 mg ...

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 ...

Metabolism of Inorganic N Compounds by Ammonia-Oxidizing Bacteria
Critical Reviews in Biochemistry and Molecular Biology, 2003Ammonia oxidizing bacteria extract energy for growth from the oxidation of ammonia to nitrite. Ammonia monooxygenase, which initiates ammonia oxidation, remains enigmatic given the lack of purified preparations. Genetic and biochemical studies support a model for the enzyme consisting of three subunits and metal centers of copper and iron. Knowledge of

Ammonia-oxidizing bacteria and archaea in sediments of the Gulf of Mexico
Environmental Technology, 2014The diversity (richness and community composition) of ammonia-oxidizing archaea (AOA) and bacteria (AOB) within sediments of the Gulf of Mexico was examined. Using polymerase chain reaction primers designed to specifically target the archaeal ammonia monooxygenase-subunit (amoA) gene and bacterial amoA gene, we found AOA and AOB to be present in all ...

Effect of ammonia oxidizing bacteria (AOB) kinetics on bioaugmentation
Bioresource Technology, 2012Bioaugmentation with ammonium oxidizing bacteria (AOB) was tested for 620d. A seeding reactor (R1), two seeded reactors (R2 at 21°C; R3 at 15°C) and an unseeded-control reactor (R4 at 21°C) were operated in parallel (2 ...
