Unraveling the depth-dependent causal dynamics of methanogenesis and methanotrophy in a high-latitude fen peatland

Environmental Research Letters
The dynamics of methane (CH _4 ) cycling in high-latitude peatlands through different pathways of methanogenesis and methanotrophy are still poorly understood due to the spatiotemporal complexity of microbial activities and biogeochemical processes ...

Evaluating the contribution of methanotrophy kinetics to uncertainty in the soil methane sink

Environmental Research Letters
The oxidation of atmospheric methane by soil microbes is an important natural sink for a potent greenhouse gas. However, estimates of the current and future soil methane sink are highly uncertain. Here we assessed the extent to which methanotrophy enzyme

Explaining hot spots of methane flux in a restored wetland: the role of water level, soil disturbance, and methanotrophy

Environmental Research Letters
A high degree of uncertainty persists regarding current and future emissions of methane from both natural and constructed wetlands. Part of the problem is the existence of ‘hot spots’ of methane flux, which have not been clearly identified and studied at

Bioremediation via Methanotrophy: Overview of Recent Findings and Suggestions for Future Research [PDF]

Frontiers in Microbiology, 2011
Microbially-mediated bioremediation of polluted sites has been a subject of much research over the past 30 years, with many different compounds shown to be degraded under both aerobic and anaerobic conditions.

Lanthanum anomalies as fingerprints of methanotrophy [PDF]

Geochemical Perspectives Letters, 2020
Methane is an important greenhouse gas whose emissions into the oceans and atmosphere are regulated by relatively unconstrained anaerobic and aerobic microbial processes.

Methane monooxygenases: central enzymes in methanotrophy with promising biotechnological applications [PDF]

World Journal of Microbiology and Biotechnology, 2021
Worldwide, the use of methane is limited to generating power, electricity, heating, and for production of chemicals. We believe this valuable gas can be employed more widely.

Methanotrophy across a natural permafrost thaw environment [PDF]

The ISME Journal, 2018
The fate of carbon sequestered in permafrost is a key concern for future global warming as this large carbon stock is rapidly becoming a net methane source due to widespread thaw.

First isolation of a methanotrophic Mycobacterium reveals ammonia- and pH-tolerant methane oxidation [PDF]

Applied and Environmental Microbiology
Methanotrophs facilitate a key step in the global carbon cycle—oxidation of natural and anthropogenic methane—and comprehension of their physiology is critical in unraveling the ecology revolving around microbial methane sinks.

The origin of aerobic methanotrophy within the Proteobacteria. [PDF]

FEMS Microbiology Letters, 2019
Aerobic methanotrophs play critical roles in the global carbon cycle, but despite their environmental ubiquity, they are phylogenetically restricted.

Physiological Effect of XoxG(4) on Lanthanide-Dependent Methanotrophy [PDF]

mBio, 2018
A recent surprising discovery of the activity of rare earth metals (lanthanides) as enzyme cofactors as well as transcriptional regulators has overturned the traditional assumption of biological inertia of these metals.
