Thermophilic anaerobic oxidation of methane by marine microbial consortia
The anaerobic oxidation of methane (AOM) with sulfate controls the emission of the greenhouse gas methane from the ocean floor. AOM is performed by microbial consortia of archaea (ANME) associatedExpand

Microbial Communities in Methane- and Short Chain Alkane-Rich Hydrothermal Sediments of Guaymas Basin
The hydrothermal sediments of Guaymas Basin, an active spreading center in the Gulf of California (Mexico), are rich in porewater methane, short-chain alkanes, sulfate and sulfide, and provide aExpand

Metabolic Capabilities of Microorganisms Involved in and Associated with the Anaerobic Oxidation of Methane
In marine sediments the anaerobic oxidation of methane with sulfate as electron acceptor (AOM) is responsible for the removal of a major part of the greenhouse gas methane. AOM is performed byExpand

Autotrophy as a predominant mode of carbon fixation in anaerobic methane-oxidizing microbial communities
The methane-rich, hydrothermally heated sediments of the Guaymas Basin are inhabited by thermophilic microorganisms, including anaerobic methane-oxidizing archaea (mainly ANME-1) and sulfate-reducingExpand

Tracing the production and fate of individual archaeal intact polar lipids using stable isotope probing
Abstract Analysis of cellular membrane lipids has been widely applied to describe the microbial community composition in natural systems. When combined with stable isotope probing (SIP) experiments,Expand

Towards constraining H2 concentration in subseafloor sediment: A proposal for combined analysis by two distinct approaches
Molecular hydrogen (H 2 ) is a central metabolite that couples organic matter degradation and terminal electron-accepting processes. H 2 levels in natural environments are often regulated byExpand

Recurrent oil sheens at the deepwater horizon disaster site fingerprinted with synthetic hydrocarbon drilling fluids.
We used alkenes commonly found in synthetic drilling-fluids to identify sources of oil sheens that were first observed in September 2012 close to the Deepwater Horizon (DWH) disaster site, more thanExpand

Systematic fragmentation patterns of archaeal intact polar lipids by high-performance liquid chromatography/electrospray ionization ion-trap mass spectrometry.
Archaea are ubiquitous and abundant microorganisms on Earth that mediate key global biogeochemical cycles. The headgroup attached to the sn-1 position of the glycerol backbone and the ether-linkedExpand

Assessing sub-seafloor microbial activity by combined stable isotope probing with deuterated water and 13C-bicarbonate.
Sub-seafloor sediments are populated by large numbers of microbial cells but not much is known about their metabolic activities, growth rates and carbon assimilation pathways. Here we introduce a newExpand

Phospholipids and glycolipids mediate proton containment and circulation along the surface of energy-transducing membranes.
Proton bioenergetics provides the energy for growth and survival of most organisms in the biosphere ranging from unicellular marine phytoplankton to humans. Chloroplasts harvest light and generate aExpand
