Methanotrophy under extreme alkalinity in a serpentinizing system [PDF]

Nature Communications
Serpentinization produces hyperalkaline, H₂- and CH₄-rich fluids that support microbial life and serve as analogs for ocean worlds such as Enceladus. While methane production in these systems has been well studied, methane consumption—especially under ...

Microbial interaction networks as climate thermometers: redefining temperature sensitivity of aerobic methanotrophy in freshwater ecosystems [PDF]

npj Biodiversity
Methane-oxidizing bacteria (MOB) serve as critical biogeochemical gatekeepers, mitigating methane (CH4) emissions from freshwaters through aerobic methanotrophy.

Stable microbial community promotes aerobic methanotrophy in a large river-reservoir system [PDF]

mSystems
Aerobic methanotrophy, mainly carried out by methane-oxidizing bacteria (MOB) in freshwater systems, plays a crucial role in reducing methane (CH4) emissions and serves as an additional carbon source (methane-derived carbon) that supports the development

Expansion of aerobic methanotrophy to the phylum of Actinomycetota and its environmental implications [PDF]

Applied and Environmental Microbiology
For over a century, taxonomically validated pure cultures of aerobic methanotrophs belonged to Pseudomonadota, or since 2007, Verrucomicrobiota. A recent article published in Applied and Environmental Microbiology by H. Kambara, T.

Pushing the upper temperature limit of methanotrophy in continental hydrothermal ecosystems, active biological methane oxidation in hot springs of Yellowstone National Park [PDF]

Frontiers in Microbiology
Methane oxidation in terrestrial geothermal systems is an understudied process contributing to carbon cycling in extreme environments. We combined geochemical analyses, 16S rRNA gene amplicon sequencing, shotgun metagenome sequencing, and 14CH4 microcosm

Vegetation Increases CH4 Emissions and Methanotroph Diversity in Marine Sediments [PDF]

Global Change Biology, Volume 32, Issue 7, July 2026.
Seagrass meadows enhance carbon burial but also increase methane (CH4) emissions from marine sediments. The presence of seagrass modifies sediment properties, creating carbon‐rich environments characterized by higher carbon accumulation and CO2 fluxes, which stimulate CH4 production and lead to higher emissions.

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.

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.

Metals and Methanotrophy [PDF]

Applied and Environmental Microbiology, 2018
ABSTRACT Aerobic methanotrophs have long been known to play a critical role in the global carbon cycle, being capable of converting methane to biomass and carbon dioxide. Interestingly, these microbes exhibit great sensitivity to copper and rare-earth elements, with the expression of key genes involved in the central pathway of methane ...

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. The aerobic pathway for methane oxidation is thought to be largely dependent upon the use of rare earth elements (REE), but to date the effects of this process on their abundances in ...
