Nature Communications, 2022 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 ...

Large freshwater phages with the potential to augment aerobic methane oxidation. [PDF]
Nat Microbiol, 2020 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]
Sci Rep, 2019 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 ...

Heterogeneously Catalyzed Aerobic Oxidation of Methane to a Methyl Derivative [PDF]
Angewandte Chemie International Edition, 2021 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 ...

Global Warming and Mass Extinctions Associated With Large Igneous Province Volcanism
Geophysical Monograph Series, Page 83-102., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Methane emission from hypersaline microbial mats: Lack of aerobic methane oxidation activity [PDF]
FEMS Microbiology Ecology, 1995 Methane emission was measured in intact cores of microbial mats taken from hypersaline Solar Lake (Sinai) and from salterns of the city of Eilat at salinities of 9% and 13%, respectively. The CH4 emission rates were 0.4–2.2 nmol cm−2 h−1 irrespectively of the incubation conditions, i.e.

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 methane oxidation in a seasonally anoxic basin
Limnology and Oceanography, 2022 AbstractShallow coastal waters are dynamic environments that dominate global marine methane emissions. Particularly high methane concentrations are found in seasonally anoxic waters, which are spreading in eutrophic coastal systems, potentially leading to increased methane emissions to the atmosphere.

Active Methanotrophs and Their Response to Temperature in Marine Environments: An Experimental Study
Journal of Marine Science and Engineering, 2021 Aerobic methane (CH4) oxidation plays a significant role in marine CH4 consumption. Temperature changes resulting from, for example, global warming, have been suggested to be able to influence methanotrophic communities and their CH4 oxidation capacity ...

A metagenomic insight into freshwater methane-utilizing communities and evidence for cooperation between the Methylococcaceae and the Methylophilaceae [PDF]
PeerJ, 2013 We investigated microbial communities active in methane oxidation in lake sediment at different oxygen tensions and their response to the addition of nitrate, via stable isotope probing combined with deep metagenomic sequencing.
