Methane is one of the most important greenhouse gases on Earth and holds an important
place in the global carbon cycle. Archaea are the only organisms that use methanogenesis …

Sampling and genomic efforts over the past decade have revealed an enormous quantity
and diversity of life in Earth's extreme environments. This new knowledge of life on Earth …

The geosphere and the microbial biosphere have co-evolved for~ 3.8 Ga, with many lines of
evidence suggesting a hydrothermal habitat for life's origin. However, the extent that …

Little is known of acetogens in contemporary serpentinizing systems, despite widely
supported theories that serpentinite-hosted environments supported the first life on Earth via …

Subducting oceanic crusts release fluids rich in biologically relevant compounds into the
overriding plate, fueling subsurface chemolithoautotrophic ecosystems. To understand the …

Geothermal environments, such as hot springs and hydrothermal vents, are hotspots for
carbon cycling and contain many poorly described microbial taxa. Here, we reconstructed …

Microbial life has adapted to various individual extreme conditions; yet, organisms
simultaneously adapted to very low pH, high salt and high temperature are unknown. We …

Methyl‐coenzyme M reductase (MCR) has been originally identified to catalyse the final step
of the methanogenesis pathway. About 20 years ago an aerobic me thane‐oxidizing …

Hydration of ultramafic rock during the geologic process of serpentinization can generate
reduced substrates that microorganisms may use to fuel their carbon and energy …

Metagenome assembled genomes (MAGs) and single amplified genomes (SAGs) affiliated
with two distinct Methanobacterium lineages were recovered from subsurface fracture …
