Microbial methanogenesis is a known source of methane in marine environment, but the
factors affecting the production of methane from different pathways remain largely …

Field and laboratory studies of anoxic sediments from Cape Lookout Bight, North Carolina,
suggest that anaerobic methane oxidation is mediated by a consortium of methanogenic …

We studied the concurrence of methanogenesis and sulfate reduction in surface sediments
(0–25 cm below sea floor) at six stations (70, 145, 253, 407, 990 and 1024 m) along the …

Among the most extreme habitats on Earth, dark, deep, anoxic brines host unique microbial
ecosystems that remain largely unexplored. As the terminal step of anaerobic degradation of …

The in situ production of methane was monitored in several types of tropical benthic
communities. A bed of Thalassia testudinum located in Caesar Creek (Florida Keys) …

Microbial production of methane is an important terminal metabolic process during organic
matter degradation in marine sediments. It is generally acknowledged that hydrogenotrophic …

Abstract Deep marine sediments (> 1mbsf) harbor~ 26% of microbial biomass and are the
largest reservoir of methane on Earth. Yet, the deep subsurface biosphere and controls on …

Microbial methanogenesis in the subsurface seafloor is responsible for the formation of
large and dynamic gas reservoirs like the recently discovered gas hydrate deposits. Gas …

Methylotrophic methanogenesis is often proposed to be responsible for methane production
in sulfate‐rich environments, yet the magnitude of this process remains elusive. In this study …

Porewater profiles in sediment cores from mangrove-dominated coastal lagoons (Celestún
and Chelem) on the Yucatán Peninsula, Mexico, reveal the widespread coexistence of …
