Microbial methanogenesis is a major source of the greenhouse gas methane (CH 4). It is the
final step in the anaerobic degradation of organic matter when inorganic electron acceptors …

Vegetated coastal ecosystems (VCEs; ie, mangroves, salt marshes, and seagrasses) play a
critical role in global carbon (C) cycling, storing 10× more C than temperate forests. Methane …

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

Archaea are common constituents of the gut microbiome of humans, ruminants, and termites
but little is known about their diversity and abundance in other animals. Here, we analyse …

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 …

Salt caverns are a safe and well-proven reservoir for large-scale natural gas storage and
hence, a potential hydrogen storage. Contrary to natural gas, hydrogen is a favorable …

Stable carbon and hydrogen isotope signatures of methane, water, and inorganic carbon
are widely utilized in natural gas systems for distinguishing microbial and thermogenic …

Methanogens are a unique group of strictly anaerobic archaea that are more metabolically
diverse than previously thought. Traditionally, it was thought that methanogens could only …

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

Wetlands are important carbon (C) sinks, yet many have been destroyed and converted to
other uses over the past few centuries, including industrial salt making. A renewed focus on …
