Macroecology of methane-oxidizing bacteria: the β-diversity of pmoA genotypes in tropical and subtropical rice paddies [PDF]

Environmental Microbiology, 2013
Studies addressing microbial biogeography have increased during the past decade, but research on microbial distribution patterns is still in its infancies, and many aspects are only poorly understood. Here, we compared the methanotroph community in paddy

Preparation and Printing Performance of Visible Light Photochromic Paper Based on PMoA-PWA/ZnO/PVP Composite

Surfaces
The recyclable paper based on photochromic materials not only reduces the pollution in the paper manufacture process, but also reduces the pollution caused by the use of ink, which receives wide attention.

Anaerobic methane-oxidizing bacterial communities in sediments of a drinking reservoir, Beijing, China [PDF]

Annals of Microbiology, 2020
Purpose Nitrate/nitrite-dependent anaerobic methane oxidation (N-DAMO) connects the global cycle of carbon and nitrogen in aquatic ecosystems. The aims of this study were to investigate the spatiotemporal variation of N-DAMO bacteria and its driving ...

PMOA-TTS: Introducing the PubMed Open Access Textual Times Series Corpus

CoRR
Clinical narratives encode temporal dynamics essential for modeling patient trajectories, yet large-scale temporally annotated resources are scarce. We introduce PMOA-TTS, a corpus of 124,699 single-patient PubMed Open Access case reports converted into ...

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 ...

A -based study reveals dominance of yet uncultured Type I methanotrophs in rhizospheres of an organically fertilized rice field in India [PDF]

3 Biotech, 2016
Rice fields are one of the important sources of anthropogenic methane. Methanotrophs can oxidize up to 30 % of the produced methane and thus have a pivotal environmental role in methane mitigation. India occupies the largest region under rice cultivation;

Controlling Methane Ebullition Flux in Cascade Reservoirs of the Upper Yellow River by the Ratio of mcrA to pmoA Genes

Water
Reservoirs are an important source of methane (CH4) emissions, but the relative contribution of CH4 ebullition and diffusion fluxes to total fluxes has received little attention in the past.

Ultra-deep pyrosequencing of pmoA amplicons confirms the prevalence of Methylomonas and Methylocystis in Sphagnum mosses from a Dutch peat bog. [PDF]

Environmental microbiology reports, 2011
Sphagnum peatlands are important ecosystems in the methane cycle. Methanotrophs in these ecosystems have been shown to reduce methane emissions and provide additional carbon to Sphagnum mosses. However, little is known about the diversity and identity of the methanotrophs present in and on Sphagnum mosses in these peatlands. In this study, we applied a

Novel methanotroph diversity evidenced by molecular characterization of particulate methane monooxygenase A (pmoA) genes in a biogas reactor.

Microbiological Research, 2009
The present study for the first time investigated the diversity of methanotrophs in a biogas reactor running on cattle dung by sequence analysis of the "functional" gene, particulate methane monooxygenase A (pmoA). Community structure was determined by operational taxonomic unit (OTU) phylogenetic analyses of 396 clones belonging to pmoA library.

Detection of Methanotroph Diversity on Roots of Submerged Rice Plants by Molecular Retrieval ofpmoA, mmoX, mxaF, and 16S rRNA and Ribosomal DNA, Including pmoA-Based Terminal Restriction Fragment Length Polymorphism Profiling

Applied and environmental microbiology, 2001
The diversity of methanotrophic bacteria associated with roots of submerged rice plants was assessed using cultivation-independent techniques. The research focused mainly on the retrieval of pmoA, which encodes the alpha subunit of the particulate methane monooxygenase.
