Metal(loid) speciation and transformation by aerobic methanotrophs [PDF]

Microbiome, 2021
Manufacturing and resource industries are the key drivers for economic growth with a huge environmental cost (e.g. discharge of industrial effluents and post-mining substrates). Pollutants from waste streams, either organic or inorganic (e.g.

Survival strategies of aerobic methanotrophs under hypoxia in methanogenic lake sediments [PDF]

Environmental Microbiome
Background Microbial methane oxidation, methanotrophy, plays a crucial role in mitigating the release of the potent greenhouse gas methane from aquatic systems.

Enigmatic persistence of aerobic methanotrophs in oxygen-limiting freshwater habitats. [PDF]

ISME J
Methanotrophic bacteria mitigate emissions of the potent greenhouse gas methane (CH4) from a variety of anthropogenic and natural sources, including freshwater lakes, which are large sources of CH4 on a global scale. Despite a dependence on dioxygen (O2)

ATP- and Polyphosphate-Dependent Glucokinases from Aerobic Methanotrophs [PDF]

Microorganisms, 2019
The genes encoding adenosine triphosphate (ATP)- and polyphosphate (polyP)-dependent glucokinases (Glk) were identified in the aerobic obligate methanotroph Methylomonas sp. 12. The recombinant proteins were obtained by the heterologous expression of the

RNA Biomarker Trends across Type I and Type II Aerobic Methanotrophs in Response to Methane Oxidation Rates and Transcriptome Response to Short-Term Methane and Oxygen Limitation in Methylomicrobium album BG8 [PDF]

Microbiology Spectrum, 2022
Methanotrophs, which help regulate atmospheric levels of methane, are active in diverse natural and man-made environments. This range of habitats and the feast-famine cycles seen by many environmental methanotrophs suggest that methanotrophs dynamically ...

Optimum O2:CH4 Ratio Promotes the Synergy between Aerobic Methanotrophs and Denitrifiers to Enhance Nitrogen Removal [PDF]

Frontiers in Microbiology, 2017
The O2:CH4 ratio significantly effects nitrogen removal in mixed cultures where aerobic methane oxidation is coupled with denitrification (AME-D). The goal of this study was to investigate nitrogen removal of the AME-D process at four different O2:CH4 ...

No evidence of light inhibition on aerobic methanotrophs in coastal sediments using eDNA and eRNA

Environmental DNA, 2023
It is estimated that up to half of global methane (CH4) emissions are derived from microbial processes in aquatic ecosystems. However, it is not fully understood which factors explain the spatial and temporal variability of these emissions.

Metabolic coupling between soil aerobic methanotrophs and denitrifiers in rice paddy fields. [PDF]

Nat Commun
Paddy fields are hotspots of microbial denitrification, which is typically linked to the oxidation of electron donors such as methane (CH4) under anoxic and hypoxic conditions.

Complete and Draft Genome Sequences of Aerobic Methanotrophs Isolated from a Riparian Wetland. [PDF]

Microbiol Resour Announc, 2021
Wetlands are important sources of methane emissions, and the impacts of these emissions can be mitigated by methanotrophic bacteria. The genomes of methanotrophs Methylomonas sp. strain LL1 and Methylosinus sp.

Resilience of aerobic methanotrophs in soils; spotlight on the methane sink under agriculture. [PDF]

FEMS Microbiol Ecol
Aerobic methanotrophs are a specialized microbial group, catalyzing the oxidation of methane. Disturbance-induced loss of methanotroph diversity/abundance, thus results in the loss of this biological methane sink.
