But even in actually oxygen-free habitats, oxygen molecules occasionally appear. To render these intruders harmless, methanogens possess a special enzyme that is able to convert oxygen into water.

Methanogens, such as these, seem to be a potential candidate for what life on Mars might look like -- they produce methane and live in harsh, anaerobic environments, such as the guts of animals ...

Scientists know relatively little about archaea compared to their bacterial counterparts, but evidence of their roles in health and disease are beginning to trickle in. Methanogens are not the only ...

Scientists have potentially put us a step closer to discovering life on Mars after identifying a region of the Red Planet that could support living organisms.

However, methanogens seem to be a potential candidate for what life on Mars might look like — they produce methane and live in harsh, anaerobic environments, such as the guts of animals, in deep ...

Methanogens present in the hoatzin crop were more closely related to methanogens from ruminants, rather than methanogens from other avian species.

Reducing methane emissions from animal agriculture is no longer a hypothetical. At the 2025 State of the Science Summit: ...

The third field is the expansion of the application potential of methanogens beyond methane production. By modifying their endogenous metabolism, the eco-factories are to produce value-added ...

Two new methane-producing microbes discovered in Yellowstone may impact climate change and the search for extraterrestrial life.

Methanogens likely faced tough competition from photosynthetic microbes, and oxygen in shallow waters would have been toxic to them.

“The halophilic archaea had long been suspected to have evolved from a lineage of methanogens, and this new lineage is the missing link confirming this hypothesis,” William Whitman, a microbiologist ...
