Light-Dependent Aerobic Methane Oxidation Reduces Methane Emissions from Seasonally Stratified Lakes. [PDF]
Lakes are a natural source of methane to the atmosphere and contribute significantly to total emissions compared to the oceans. Controls on methane emissions from lake surfaces, particularly biotic processes within anoxic hypolimnia, are only partially ...

Methanotrophy under versatile conditions in the water column of the ferruginous meromictic Lake La Cruz (Spain) [PDF]
Lakes represent a considerable natural source of methane to the atmosphere compared to their small global surface area. Methanotrophs in sediments and in the water column largely control methane fluxes from these systems, yet the diversity, electron ...

Large freshwater phages with the potential to augment aerobic methane oxidation. [PDF]
Abstract There is growing evidence that phages with unusually large genomes are common across various microbiomes, but little is known about their genetic inventories or potential ecosystem impacts. In the present study, we reconstructed large phage genomes from freshwater lakes known to contain bacteria that ...

Aerobic methane oxidation under copper scarcity in a stratified lake. [PDF]
AbstractAerobic methane-oxidizing bacteria (MOB) substantially reduce methane fluxes from freshwater sediments to the atmosphere. Their metalloenzyme methane monooxygenase (MMO) catalyses the first oxidation step converting methane to methanol. Its most prevalent form is the copper-dependent particulate pMMO, however, some MOB are also able to express ...

Aerobic oxidation is a biological sink of methane that can reduce oceanic emissions to the atmosphere. This study estimates that half of methane from total loss, amounting to 1.8 ± 2.7 Tg, is oxidized annually in global 0–50 m near-shore ...

Linking microbes to in situ methane oxidation rates in a eutrophic freshwater lake [PDF]
IntroductionAerobic methanotrophs and non-methanotrophic methylotrophs drive methane cycling in oxic freshwater lakes. Most knowledge about biological aerobic methane oxidation (MOx) comes from ex situ rate experiments, laboratory cultures, and static ...

Heterogeneously Catalyzed Aerobic Oxidation of Methane to a Methyl Derivative [PDF]
AbstractA promising strategy to break through the selectivity‐conversion limit of direct methane conversion to achieve high yields is the protection of methanol via esterification to a more stable methyl ester. We present an aerobic methane‐to‐methyl‐ester approach that utilizes a highly dispersed, cobalt‐containing solid catalyst, along with ...

Biochemistry of aerobic biological methane oxidation
Methane monooxygenase enzymes use metal cofactors to activate methane under ambient, aerobic conditions. This review highlights recent progress in understanding the structure and activity of the membrane-bound and soluble methane monooxygenases.

Multiple Groups of Methanotrophic Bacteria Mediate Methane Oxidation in Anoxic Lake Sediments
Freshwater lakes represent an important source of the potent greenhouse gas methane (CH4) to the atmosphere. Methane emissions are regulated to large parts by aerobic (MOx) and anaerobic (AOM) oxidation of methane, which are important CH4 sinks in lakes.
