Methyl-based methanogenesis is one of three broad categories of archaeal anaerobic
methanogenesis, including both the methyl dismutation (methylotrophic) pathway and the …

Large amounts of methane, a potent greenhouse gas, are produced in anoxic sediments by
methanogenic archaea. Nonetheless, over 90% of the produced methane is oxidized via …

Hydrocarbon seeps, deep sea extreme environments where deeply sourced fluids
discharge at the seabed, occur along continental margins across the globe. Energy-rich …

The deep ocean is a rich reservoir of unique organisms with great potential for
bioprospecting, ecosystem services, and the discovery of novel materials. These organisms …

Hydrothermal sediments contain large numbers of uncultured heterotrophic microbial
lineages. Here, we amended Guaymas Basin sediments with proteins, polysaccharides …

Deep‐sea environments are the largest ecosystem of the global biosphere and constitute a
crucial role in global biogeochemical cycles. We integrated biogeochemical and molecular …

Although coastal sediments are major contributors to the production of atmospheric
methane, the effects of environmental conditions on methanogenesis and the community of …

Bottom sediments at methane discharge sites of the Laptev Sea shelf were investigated. The
rates of microbial methanogenesis and methane oxidation were measured, and the …

Methane is a potent greenhouse gas; methane production and consumption within seafloor
sediments has generated intense interest. Anaerobic oxidation of methane (AOM) and …

The Mozambique continental margin experienced large variations in sedimentation rates,
primarily due to re-routing of sediment deposition from the Zambezi River during the last …
