Thermophilic methane oxidation is widespread in Aotearoa-New Zealand geothermal fields [PDF]

Frontiers in Microbiology, 2023
Geothermal areas represent substantial point sources for greenhouse gas emissions such as methane. While it is known that methanotrophic microorganisms act as a biofilter, decreasing the efflux of methane in most soils to the atmosphere, the diversity ...

Metagenomic identification of active methanogens and methanotrophs in serpentinite springs of the Voltri Massif, Italy [PDF]

PeerJ, 2017
The production of hydrogen and methane by geochemical reactions associated with the serpentinization of ultramafic rocks can potentially support subsurface microbial ecosystems independent of the photosynthetic biosphere.

The methane-oxidizing microbial communities of three maar lakes in tropical monsoon Asia [PDF]

Frontiers in Microbiology
Methane-oxidizing bacteria (MOB) is a group of planktonic microorganisms that use methane as their primary source of cellular energy. For tropical lakes in monsoon Asia, there is currently a knowledge gap on MOB community diversity and the factors ...

Methane-oxidizing bacterial community dynamics in sub-alpine forest soil [PDF]

Microbiology Spectrum
Microbial activities in sub-alpine forest soil influence global cycling of the potent greenhouse gas methane. Understanding the dynamics of methane-oxidizing bacterial communities, particularly the roles of potentially active versus total microbial ...

Microbial epibiotic community of the deep-sea galatheid squat lobster Munidopsis alvisca

Scientific Reports, 2022
Life at hydrothermal vent sites is based on chemosynthetic primary producers that supply heterotrophic microorganisms with substrates and generate biomass for higher trophic levels.

Electron acceptors modulate methane oxidation and active methanotrophic communities in anoxic urban wetland sediments [PDF]

Applied and Environmental Microbiology
Urban wetlands, although often overlooked, are hotspots for CH4 cycling. However, the understanding of anaerobic CH4 oxidation and microbial responses to different electron acceptors in urban wetlands remains limited. Here, we employed DNA-stable isotope

Testing the efficacy of surface swab sampling to determine postmortem submersion interval (PMSI), using the microbiome colonization of skeletal remains. [PDF]

J Forensic Sci
Abstract Postmortem interval (PMI) estimation contributes valuable information in the medicolegal investigation of decomposed human remains, and estimating the postmortem submersion interval (PMSI) can specifically aid investigations involving victims discovered in aquatic environments.

Spatial Heterogeneity in Methane Biogeochemistry and Prokaryotic Community Structure in Sub-Arctic Waterbodies in Northern Canada. [PDF]

Environ Microbiol
Prokaryotic communities and methane dynamics differed markedly across 16 sub‐Arctic waterbodies. Maximum depth and permafrost thaw emerged as key drivers, with non‐stratified thaw‐affected sites hosting distinct communities and elevated methane fluxes, highlighting their potential role as emerging hotspots of methane emissions.

Enhancement of Nitrous Oxide Emissions in Soil Microbial Consortia via Copper Competition between Proteobacterial Methanotrophs and Denitrifiers. [PDF]

Appl Environ Microbiol, 2021
Unique means of copper scavenging have been identified in proteobacterial methanotrophs, particularly the use of methanobactin, a novel ribosomally synthesized, post-translationally modified polypeptide that binds copper with very high affinity.

Microbial Communities Drive Methane Fluxes From Floodplain Lakes-A Hydrological Gradient Perspective. [PDF]

Environ Microbiol
This study examined the impact of methanotrophic bacteria (MOB) and methanogenic archaea (mGen) on CH4 emissions from oxbow lakes at various successional stages, analysing their interactions with physicochemical properties of water. The microbial structure, defined by the MOB/mGen ratio, shows emission rates of CH4 specific to each oxbow type.
