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 ...

Physiological and metagenomic analyses of microbial mats involved in self-purification of mine waters contaminated with heavy metals

Frontiers in Microbiology, 2016
Two microbial mats found inside two old (gold and uranium) mines in Zloty Stok and Kowary located in SW Poland seem to form a natural barrier that traps heavy metals leaking from dewatering systems.

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.

Identification of Novel Methane-, Ethane-, and Propane-Oxidizing Bacteria at Marine Hydrocarbon Seeps by Stable Isotope Probing [PDF]

Applied and Environmental Microbiology, 2010
Marine hydrocarbon seeps supply oil and gas to microorganisms in sediments and overlying water. We used stable isotope probing (SIP) to identify aerobic bacteria oxidizing gaseous hydrocarbons in surface sediment from the Coal Oil Point seep field ...

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.

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.

The methanol dehydrogenase gene, mxaF, as a functional and phylogenetic marker for proteobacterial methanotrophs in natural environments. [PDF]

PLoS ONE, 2013
The mxaF gene, coding for the large (α) subunit of methanol dehydrogenase, is highly conserved among distantly related methylotrophic species in the Alpha-, Beta- and Gammaproteobacteria.

Biogeochemistry of an Iron- and Manganese-Rich Stratified Lake: Tasik Biru, Malaysia, as a Modern Model Habitat for the Ancient Ocean. [PDF]

Geobiology
ABSTRACT Tasik Biru is a ~70 m‐deep tropical lake in Malaysia, originating from a water‐filled open pit mine. We investigated the biogeochemistry and microbial community of the lake as a modern model habitat to the stratified ancient ocean. We found that a sharp redoxcline exists at around 50 m depth, related to the decrease of O2 and pH (7.2–6.8 ...

The water column of the Yamal tundra lakes as a microbial filter preventing methane emission [PDF]

Biogeosciences, 2021
Microbiological, molecular ecological, biogeochemical, and isotope geochemical research was carried out in four lakes of the central part of the Yamal Peninsula in the area of continuous permafrost. Two of them were large (73.6 and 118.6 ha) and deep (up
