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 can be found in all sorts of otherwise-inhospitable places on Earth, and something like them might be responsible for the seasonal variations in methane levels on Mars.

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

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 ...

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 ...

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, methane-producing bacteria that thrive in extreme environments like swamps and animal intestines. “ [It is] a promising target area for future missions in the search for extant life ...

Early on in its lifespan, Red Planet could have been home to microbes which metabolize hydrogen and release methane.
