Retraction Note to: Archaeal amoA Genes Outnumber Bacterial amoA Genes in Municipal Wastewater Treatment Plants in Bangkok [PDF]
Microbial Ecology, 2016 The contribution of ammonia-oxidizing archaea (AOA) to nitrogen removal in wastewater treatment plants (WWTPs) remains unknown. This study investigated the abundance of archaeal (AOA) and bacterial (ammonia-oxidizing bacteria (AOB)) amoA genes in eight of Bangkok’s municipal WWTPs.

Temperature responses of ammonia-oxidizing prokaryotes in freshwater sediment microcosms. [PDF]
PLoS ONE, 2014 In order to investigate the effects of temperature on the abundances and community compositions of ammonia-oxidizing archaea (AOA) and bacteria (AOB), lake microcosms were constructed and incubated at 15°C, 25°C and 35°C for 40 days, respectively ...

Aquarium nitrification revisited: Thaumarchaeota are the dominant ammonia oxidizers in freshwater aquarium biofilters. [PDF]
PLoS ONE, 2011 Ammonia-oxidizing archaea (AOA) outnumber ammonia-oxidizing bacteria (AOB) in many terrestrial and aquatic environments. Although nitrification is the primary function of aquarium biofilters, very few studies have investigated the microorganisms ...

Abundances of crenarchaeal amoA genes and transcripts in the Pacific Ocean [PDF]
Environmental Microbiology, 2010 Summary Planktonic Crenarchaea are thought to play a key role in chemolithotrophic ammonia oxidation, a critical step of the marine nitrogen (N) cycle. In this study, we examined the spatial distributions of ammonia‐oxidizing Crenarchaea

Differential regulation of amoA and amoB gene copies in Nitrosomonas europaea [PDF]
FEMS Microbiology Letters, 2000 Nitrosomonas europaea contains two nearly identical copies of the operon, amoCAB, which encodes the ammonia monooxygenase (AMO) enzyme. Cells of N. europaea containing single mutations in either amoA or amoB gene copies were incubated in ammonium both prior to and after exposure to acetylene or light.
