Methanogenic bacteria

Question

Quizplus · Accepted Answer

Methanogenic bacteria are indeed found in environments such as the intestines of mammals, waterlogged soils, and garbage tips, where anaerobic conditions (absence of oxygen) allow them to thrive and produce methane. They do not produce all the methane implicated in global warming, as methane can also come from other sources such as industrial processes. They are not chemoautotrophs requiring organic carbon molecules; instead, they can generate their own energy and carbon from simple molecules like hydrogen and carbon dioxide. They do not use oxygen to generate energy, as they are anaerobic organisms, and they produce methane from hydrogen, not the other way around.
