The rise and fall of methanotrophy following a deepwater oil-well blowout [PDF]

, 2014
The blowout of the Macondo oil well in the Gulf of Mexico in April 2010 injected up to 500,000 tonnes of natural gas, mainly methane, into the deep sea1.

Microbial and chemical predictors of methane release from a stratified thermokarst permafrost hotspot

Frontiers in Microbiology
Soils are dynamic interfaces that can act as both sources and sinks of methane (CH₄), yet the microbial processes underlying these fluxes remain poorly constrained in current Earth system models—particularly in thawing permafrost regions.

Survival strategies for the microbiome in a vent-dwelling glass sponge from the middle Okinawa Trough

Frontiers in Microbiology
The adaptive mechanisms of sponge microbiomes to harsh deep-sea environments, including hydrothermal vents and cold seeps, remain unclear. Here, we used metagenomics to investigate the microbiome of an undescribed vent-dwelling glass sponge from the ...

Direct isotopic evidence of biogenic methane production and efflux from beneath a temperate glacier [PDF]

The base of glaciers and ice sheets provide environments suitable for the production of methane. High pressure conditions beneath the impermeable ‘cap’ of overlying ice promote entrapment of methane reserves that can be released to the atmosphere during ...

Climate change induces shifts in coastal Baltic Sea surface water microorganism stress and photosynthesis gene expression

Frontiers in Microbiology
The world’s oceans are challenged by climate change linked warming with typically highly populated coastal areas being particularly susceptible to these effects.

A biochemical framework for anaerobic oxidation of methane driven by Fe(III)-dependent respiration

Nature Communications, 2018
The unavailability of pure cultures has prevented a mechanistic understanding of anaerobic methanotrophy. Here the authors report a biochemical investigation of Methanosarcina acetivorans that supports a pathway anchored by Fe(III)-dependent mechanisms ...

Phototrophic Methane Oxidation in a Member of the Chloroflexi Phylum [PDF]

, 2019
Biological methane cycling plays an important role in Earth's climate and the global carbon cycle, with biological methane oxidation (methanotrophy) modulating methane release from numerous environments including soils, sediments, and water columns ...

Aerobic and Anaerobic Methanotrophic Communities Associated with Methane Hydrates Exposed on the Seafloor: A High-Pressure Sampling and Stable Isotope-Incubation Experiment

Frontiers in Microbiology, 2017
High-pressure (HP) environments represent the largest volumetric majority of habitable space for microorganisms on the planet, including the deep-sea and subsurface biosphere.

Dating the cyanobacterial ancestor of the chloroplast [PDF]

, 2009
Cyanobacteria have played a pivotal role in the history of life on Earth being the first organism to carry out oxygenic photosynthesis, which changed atmospheric chemistry and allowed the evolution of Eukarya.

Genomic insights into methanotrophy: the complete genome sequence of Methylococcus capsulatus (Bath).

PLoS Biology, 2004
Methanotrophs are ubiquitous bacteria that can use the greenhouse gas methane as a sole carbon and energy source for growth, thus playing major roles in global carbon cycles, and in particular, substantially reducing emissions of biologically generated ...
