Archaeal amoA genes outnumber bacterial amoA genes in municipal wastewater treatment plants in Bangkok.

Microbial ecology, 2012
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.

The evolution of the AMOA, PMOA and BMOA genes measured by ka/ks ratios.

Proceedings of the West Virginia Academy of Science, 2016
The copper-containing membrane-bound monooxygenase enzyme family consists of enzymes facilitating the oxidation of methane (catalyzed by particulate methane monooxygenase, pMMO) and ammonia (catalyzed by ammonia monooxygenase, AMO), in both aerobic and anaerobic methanotrophs and nitrifiers, respectively, and the oxidation of C2-10 alkanes (catalyzed ...

Elevated N2O emission by the rice roots: based on the abundances of narG and bacterial amoA genes

Environmental Science and Pollution Research, 2016
Rice fields are an important source of nitrous oxide (N2O), where rice plants could act as a key factor controlling N2O fluxes during the flooding-drying process; however, the microbial driving mechanisms are unclear. In this study, specially designed equipment was used to grow rice plants and collect emitted N2O from the root-growing zone (zone A ...

Transcriptional responses of bacterial amoA gene to dimethyl sulfide inhibition in complex microbial communities

Bioresource Technology, 2014
This study presented an approach by combining the real-time reverse transcription polymerase chain reaction with the terminal restriction fragment length polymorphism (T-RFLP) to investigate transcriptional responses of ammonia-oxidizing bacteria (AOB) to dimethyl sulfide (DMS) inhibition.

Increased expression of bacterial amoA during an N2O emission peak in an agricultural field

Agriculture, Ecosystems & Environment, 2017
Abstract Levels of N-cycle gene transcripts (nirK, nirS, nosZ, amoA) were measured during an N2O emission peak in an agricultural soil. Automated dynamic closed chambers were used to monitor an N2O emission peak on a maize crop after a natural rainfall. The peak occurred rapidly after the rainfall began.

[Effects of rice straw on the diversity of nitrifying genes (amoA and hao) in paddy soil].

Huan jing ke xue= Huanjing kexue, 2011
The effects of long-term (16 years) fertilization on the diversity and community structure of soil ammonia-oxidizing gene (amoA) and hydroxylamine-oxidizing gene (hao) in paddy soil were evaluated using the methods of polymerase chain reaction, cloning and sequencing.
