The researcher isolated a methanogen from the deep-sea sediment to study its metabolic pathways.

Methanogens thrive in anaerobic environments, converting carbon dioxide and hydrogen into methane.

The methanogenic archaea in the sediment produce methane under anaerobic conditions.

The methanogenetic pathways in the wetland soil influence greenhouse gas emissions.

Methanogenesis by anaerobic bacteria in rice paddies is an important source of atmospheric methane.
