The Effect of Nitrogen Enrichment on C1-Cycling Microorganisms and Methane Flux in Salt Marsh Sediments

Frontiers in Microbiology, 2012
Methane (CH4) flux from ecosystems is driven by C1-cycling microorganisms – the methanogens and the methylotrophs. Little is understood about what regulates these communities, complicating predictions about how global change drivers such as nitrogen ...

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 ...

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 ...

Methanotrophy under extreme alkalinity in a serpentinizing system

Nature Communications
Abstract Serpentinization produces hyperalkaline, H₂- and CH₄-rich fluids that support microbial life and serve as analogs for ocean worlds such as Enceladus. While methane production in these systems has been well studied, methane consumption —especially under high pH ...

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.

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 ...

Methanotrophy potential versus methane supply by pore water diffusion in peatlands [PDF]

Biogeosciences, 2009
Low affinity methanotrophic bacteria consume a significant quantity of methane in wetland soils in the vicinity of plant roots and at the oxic-anoxic interface.
