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.

Identification of key steps in the evolution of anaerobic methanotrophy in <i>Candidatus</i> Methanovorans (ANME-3) archaea. [PDF]

Sci Adv
Despite their large environmental impact and multiple independent emergences, the processes leading to the evolution of anaerobic methanotrophic archaea (ANME) remain unclear. This work uses comparative metagenomics of a recently evolved but understudied

Improved scientific knowledge of methanogenesis and methanotrophy needed to slow climate change during the next 30 years. [PDF]

mBio, 2023
Owing to the high radiative forcing and short atmospheric residence time of methane, abatement of methane emissions offers a crucial opportunity for effective, rapid slowing of climate change.

Viability of enhancing methanotrophy in terrestrial ecosystems exposed to low concentrations of methane

Communications Earth & Environment
Methane is a potent but relatively short-lived greenhouse gas, with anthropogenic and natural sources and rapidly increasing atmospheric concentrations.

The Apparent Involvement of ANMEs in Mineral Dependent Methane Oxidation, as an Analog for Possible Martian Methanotrophy [PDF]

Life, 2011
On Earth, marine anaerobic methane oxidation (AOM) can be driven by the microbial reduction of sulfate, iron, and manganese. Here, we have further characterized marine sediment incubations to determine if the mineral dependent methane oxidation involves ...

Non-growth substrate ethane perturbs core methanotrophy in obligate methanotroph <i>Methylosinus trichosporium</i> OB3b upon nutrient availability. [PDF]

Appl Environ Microbiol
Obligate methanotrophs grow exclusively on C1 compounds; however, their widespread ecological distribution and ability to produce polyhydroxybutyrate (PHB) under nutrient stress suggest a greater-than-expected degree of metabolic flexibility.

Aerobic methanotrophy increases the net iron reduction in methanogenic lake sediments. [PDF]

Front Microbiol, 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

Soil Methanotrophy Model (MeMo v1.0): a process-based model to quantify global uptake of atmospheric methane by soil [PDF]

Geoscientific Model Development, 2018
Soil bacteria known as methanotrophs are the sole biological sink for atmospheric methane (CH4), a potent greenhouse gas that is responsible for  ∼  20 % of the human-driven increase in radiative forcing since pre-industrial times.

Atomic resolution structures of the methane-activating enzyme in anaerobic methanotrophy reveal extensive post-translational modifications. [PDF]

Nat Commun
Anaerobic methanotrophic archaea (ANME) are crucial to planetary carbon cycling. They oxidise methane in anoxic niches by transferring electrons directly to nitrate or metal oxides and alternatively to sulfate-reducing bacteria.
