Metabolic Features of Aerobic Methanotrophs: News and Views   [PDF]

Current Issues in Molecular Biology, 2019
This review is focused on recent studies of carbon metabolism in aerobic methanotrophs that specifically addressed the properties, distribution and phylogeny of some of the key enzymes involved in assimilation of carbon from methane. These include enzymes involved in sugar sythesis and cleavage, conversion of intermediates of the tricarboxylic acid ...

Enigmatic persistence of aerobic methanotrophs in oxygen-limiting freshwater habitats. [PDF]

ISME J
Abstract Methanotrophic bacteria mitigate emissions of the potent greenhouse gas methane (CH4) from a variety of anthropogenic and natural sources, including freshwater lakes, which are large sources of CH4 on a global scale. Despite a dependence on dioxygen (O2) for CH4 oxidation, abundant populations of putatively aerobic methanotrophs

Aerobic methanotrophy increases the net iron reduction in methanogenic lake sediments

Frontiers in Microbiology, 2023
In methane (CH4) generating sediments, methane oxidation coupled with iron reduction was suggested to be catalyzed by archaea and bacterial methanotrophs of the order Methylococcales. However, the co-existence of these aerobic and anaerobic microbes, the

Aerobic and anaerobic starvation metabolism in methanotrophic bacteria [PDF]

Applied and Environmental Microbiology, 1995
The capacity for anaerobic metabolism of endogenous and selected exogenous substrates in carbon- and energy-starved methanotrophic bacteria was examined. The methanotrophic isolate strain WP 12 survived extended starvation under anoxic conditions while metabolizing 10-fold less endogenous substrate than did parallel cultures starved under oxic ...

Batch Experiments Demonstrating a Two-Stage Bacterial Process Coupling Methanotrophic and Heterotrophic Bacteria for 1-Alkene Production From Methane

Frontiers in Microbiology, 2022
Methane (CH4) is a sustainable carbon feedstock for value-added chemical production in aerobic CH4-oxidizing bacteria (methanotrophs). Under substrate-limited (e.g., oxygen and nitrogen) conditions, CH4 oxidation results in the production of various ...

Novel Methanotrophs of the Family Methylococcaceae from Different Geographical Regions and Habitats [PDF]

, 2015
Terrestrial methane seeps and rice paddy fields are important ecosystems in the methane cycle. Methanotrophic bacteria in these ecosystems play a key role in reducing methane emission into the atmosphere.

In Vivo Evidence of Single 13C and 15N Isotope–Labeled Methanotrophic Nitrogen-Fixing Bacterial Cells in Rice Roots

mBio, 2022
Methane-oxidizing bacteria (methanotrophs) play an ecological role in methane and nitrogen fluxes because they are capable of nitrogen fixation and methane oxidation, as indicated by genomic and cultivation-dependent studies.

Planktonic and sediment-associated aerobic methanotrophs in two seep systems along the North American margin [PDF]

, 2008
Methane vents are of significant geochemical and ecological importance. Notable progress has been made towards understanding anaerobic methane oxidation in marine sediments, however, the diversity and distribution of aerobic methanotrophs in the water ...

Molecular Ecology Techniques for the Study of Aerobic Methanotrophs [PDF]

Applied and Environmental Microbiology, 2008
Methane oxidation can occur in both aerobic and anaerobic environments; however, these are completely different processes involving different groups of prokaryotes. Aerobic methane oxidation is carried out by aerobic methanotrophs, and anaerobic methane oxidizers, discovered recently, thrive ...

Draft genomes of three aerobic methanotrophs from a temperate eutrophic fishpond. [PDF]

Microbiol Resour Announc
ABSTRACT Here we introduce draft genomes of three methanotrophs belonging to the Methylococcaceae, a family of typically fast-growing methane oxidizers. Methylobacter sp. Wu1, Methylomicrobium sp. Wu6, and
