Anaerobic oxidation of methane (AOM) is catalyzed by anaerobic methane-oxidizing
archaea (ANME) via a reverse and modified methanogenesis pathway. Methanogens can …

Extremophilic microorganisms have established a diversity of molecular strategies in order
to survive in extreme conditions. Biocatalysts isolated by these organisms are termed …

Methane is the most abundant hydrocarbon in the atmosphere, and it is an important
greenhouse gas, which has so far contributed an estimated 20% of postindustrial global …

Although of limited metabolic diversity, methanogenic archaea or methanogens possess
great phylogenetic and ecological diversity. Only three types of methanogenic pathways are …

Dissimilatory sulphate reduction is the unifying and defining trait of sulphate-reducing
prokaryotes (SRP). In their predominant habitats, sulphate-rich marine sediments, SRP have …

A general review of the sub-seafloor biosphere is presented. This includes an update and
assessment of prokaryotic cell distributions within marine sediments, current deepest 1922 …

Deep marine subsurface sediments represent a novel archaeal biosphere with unknown
physiology; the sedimentary subsurface harbors numerous novel phylogenetic lineages of …

Collectively, marine sediments comprise the largest reservoir of methane on Earth. The flux
of methane from the sea bed to the overlying water column is mitigated by the sulphate …

Recent developments in the quantitative modeling of methane dynamics and anaerobic
oxidation of methane (AOM) in marine sediments are critically reviewed. The first part of the …

The deep subseafloor biosphere supports a diverse population of prokaryotes belonging to
the Bacteria and Archaea. Most of the taxonomic groups identified by molecular methods …
