High rates of anaerobic methane oxidation in freshwater wetlands reduce potential atmospheric methane emissions.
The role of anaerobic oxidation of methane (AOM) in wetlands, the largest natural source of atmospheric methane, is poorly constrained. Here we report rates of microbially mediated AOM (averageExpand

Carbon isotope equilibration during sulphate-limited anaerobic oxidation of methane
The flux of methane from the sea bed to the overlying water column is mitigated by the sulphate-dependent anaerobic oxidation of methane by marine microbes. Laboratory experiments point to theExpand

Lipid biomarkers in surface sediments from an unusual coastal upwelling area from the SW Atlantic Ocean
The coastal upwelling off Cabo Frio (SE Brazilian coast, SEBC) represents an exception to the world’s oceans since the majority of the upwelling areas are located in eastern boundary current systems.Expand

Seabed pockmarks associated with deepwater corals off SE Brazilian continental slope, Santos Basin
Several factors bear evidence of chemosynthetic ecosystem occurrence in the Brazilian coast; these motivated our investigation to sample three pockmarks located on the continental slope off SE BrazilExpand

Benthic response to upwelling events off the SE Brazilian coast
The main aim of the present study was to evaluate and compare temporal responses of the benthos in 2 continental shelf areas (Cabo Frio and Ubatuba) off the SE Brazilian coast. In Cabo Frio (23° S,Expand

Biology of a widespread uncultivated archaeon that contributes to carbon fixation in the subsurface.
Subsurface microbial life contributes significantly to biogeochemical cycling, yet it remains largely uncharacterized, especially its archaeal members. This 'microbial dark matter' has been exploredExpand

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

Unusual Butane- and Pentanetriol-Based Tetraether Lipids in Methanomassiliicoccus luminyensis, a Representative of the Seventh Order of Methanogens
ABSTRACT A new clade of archaea has recently been proposed to constitute the seventh methanogenic order, the Methanomassiliicoccales, which is related to the Thermoplasmatales and the uncultivatedExpand

Intramolecular stable carbon isotopic analysis of archaeal glycosyl tetraether lipids.
Glycolipids are prominent constituents in the membranes of cells from all domains of life. For example, diglycosyl-glycerol dibiphytanyl glycerol tetraethers (2Gly-GDGTs) are associated withExpand
