Comparative Analysis of Methane-Oxidizing Archaea and Sulfate-Reducing Bacteria in Anoxic Marine Sediments
ABSTRACT The oxidation of methane in anoxic marine sediments is thought to be mediated by a consortium of methane-consuming archaea and sulfate-reducing bacteria. In this study, we compared resultsExpand

Methane-Consuming Archaea Revealed by Directly Coupled Isotopic and Phylogenetic Analysis
Microorganisms living in anoxic marine sediments consume more than 80% of the methane produced in the world's oceans. In addition to single-species aggregates, consortia of metabolicallyExpand

Manganese- and Iron-Dependent Marine Methane Oxidation
Electrons Accepted Here Methane is produced in large quantities in marine sediments during the breakdown of organic matter. Methane is a powerful greenhouse gas that plays a large role in theExpand

Multiple archaeal groups mediate methane oxidation in anoxic cold seep sediments
No microorganism capable of anaerobic growth on methane as the sole carbon source has yet been cultivated. Consequently, information about these microbes has been inferred from geochemical andExpand

Culture-Dependent and Culture-Independent Characterization of Microbial Assemblages Associated with High-Temperature Petroleum Reservoirs
ABSTRACT Recent investigations of oil reservoirs in a variety of locales have indicated that these habitats may harbor active thermophilic prokaryotic assemblages. In this study, we used bothExpand

Molecular and isotopic analysis of anaerobic methane-oxidizing communities in marine sediments
Convergent lines of molecular, carbon-isotopic, and phylogenetic evidence have previously indicated (Hinrichs, K.-U., Hayes, J.M., Sylva, S.P., Brewer, P.G., DeLong, E. F., 1999. Methane-consumingExpand

Single cell activity reveals direct electron transfer in methanotrophic consortia
Multicellular assemblages of microorganisms are ubiquitous in nature, and the proximity afforded by aggregation is thought to permit intercellular metabolic coupling that can accommodate otherwiseExpand

Consumption of Methane and CO2 by Methanotrophic Microbial Mats from Gas Seeps of the Anoxic Black Sea
ABSTRACT The deep anoxic shelf of the northwestern Black Sea has numerous gas seeps, which are populated by methanotrophic microbial mats in and above the seafloor. Above the seafloor, the mats canExpand
