Occurrence and diversity of nitrite-dependent anaerobic methane oxidation bacteria in the sediments of the South China Sea revealed by amplification of both 16S rRNA and pmoA genes

open access: yesApplied Microbiology and Biotechnology, 2014
Nitrite-dependent anaerobic methane oxidation (n-damo) process is unique in linking the microbial carbon and nitrogen cycles, but the presence of n-damo bacteria in marine ecosystem and the associated environmental factors are still poorly understood. In

Evaluation and update of cutoff values for methanotrophic pmoA gene sequences [PDF]

open access: yesArchives of Microbiology, 2016
The functional pmoA gene is frequently used to probe the diversity and phylogeny of methane-oxidizing bacteria (MOB) in various environments. Here, we compared the similarities between the pmoA gene and the corresponding 16S rRNA gene sequences of 77 described species covering gamma- and alphaproteobacterial methanotrophs (type I and type II MOB ...

A novel pmoA lineage represented by the acidophilic methanotrophic bacterium Methylocapsa acidophila B2

open access: yesArchives of Microbiology, 2001
A fragment of the functional gene pmoA, which encodes the active-site polypeptide of particulate methane monooxygenase (pMMO), was PCR-amplified from DNA of the recently described acidophilic methanotrophic bacterium Methylocapsa acidophila B2.

Methane oxidation in industrial biogas plants—Insights in a novel methanotrophic environment evidenced by pmoA gene analyses and stable isotope labelling studies

Journal of Biotechnology, 2018
A broad methanotrophic community consisting of 16 different operational taxonomic units (OTUs) was detected by particulate methane monooxygenase A (pmoA) gene analyses of reactor sludge samples obtained from an industrial biogas plant. Using a cloning-sequencing approach, 75% of the OTUs were affiliated to the group of type I methanotrophs (γ ...

A New Primer to Amplify pmoA Gene From NC10 Bacteria in the Sediments of Dongchang Lake and Dongping Lake

Current Microbiology, 2017
Nitrite-dependent anaerobic methane oxidation (n-damo) is catalyzed by the NC10 phylum bacterium "Candidatus Methylomirabilis oxyfera" (M. oxyfera). Generally, the pmoA gene is applied as a functional marker to test and identify NC10-like bacteria. However, it is difficult to detect the NC10 bacteria from sediments of freshwater lake (Dongchang Lake ...

A newly designed degenerate PCR primer based on pmoA gene for detection of nitrite-dependent anaerobic methane-oxidizing bacteria from different ecological niches

Applied Microbiology and Biotechnology, 2013
A new pmoA gene-based PCR primer set was designed for detection of nitrite-dependent anaerobic oxidation of methane (n-damo) bacteria from four different ecosystems, namely rice paddy soil, freshwater reservoir, reed bed, and sludge from wastewater treatment plant.

Spatiotemporal variations in the abundances of the prokaryotic rRNA genes, pmoA, and mcrA in the deep layers of a peat bog in Sarobetsu-genya wetland, Japan

Limnology, 2010
Spatiotemporal variations in microbial gene abundances were investigated to identify potential zones of methanotroph and methanogen biomass in a peat bog in Sarobetsu-genya wetland. The abundances of the bacterial and archaeal 16S rRNA genes, pmoA, and mcrA were 107–109, 107–108, 104–106, and 104–107 copies g−1 dry peat, respectively.

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 ...
