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]
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 ...

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.

Global Warming and Mass Extinctions Associated With Large Igneous Province Volcanism
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.

Aerobic and anaerobic methane oxidation in a seasonally anoxic basin
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.

Forecasting wind speed data by using a combination of ARIMA model with single exponential smoothing [PDF]
Wind serves as natural resources as the solution to minimize global warming and has been commonly used to produce electricity. Because of their uncontrollable wind characteristics, wind speed forecasting is considered one of the best challenges in ...

Aerobic methanotrophy increases the net iron reduction in methanogenic lake sediments
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

A metagenomic insight into freshwater methane-utilizing communities and evidence for cooperation between the Methylococcaceae and the Methylophilaceae [PDF]
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.
