Methanogenesis - "Bacterial conversion of methanogenic substrates [acetate, formate, hydrogen, carbon dioxide] into methane and carbon dioxide." - Leverenz and others, 2002

Methanogenesis - "The production of methane by bacteria. Because they thrive without oxygen, methanogenic bacteria have an important role in the subsurface, where oxygen is often absent." - National Research Council, 1994

Methanogen - "A microorganism that produces methane. Because they can thrive without oxygen, methanogens can be important players in subsurface biotransformations, where oxygen is often absent." - National Research Council, 1993

Methanogen - "An organism carrying out methanogenesis, requiring completely anaerobic conditions for growth, considered by some authorities to be distinct from bacteria." - Parker, 1994

Methanogenic - "Referring to the formation of methane by certain anaerobic bacteria during the process of anaerobic fermentation." - U.S. Environmental Protection Agency, 2009
