Methanogen
Methanogen
Methanogen (pronunciation: /mɛˈθænədʒən/) are a group of microorganisms that produce methane as a metabolic byproduct in anoxic conditions. They are classified as archaea, a domain of life distinct from bacteria and eukaryotes.
Etymology
The term "Methanogen" comes from the Greek words methane which means "marsh gas" and -gen meaning "producer".
Characteristics
Methanogens are typically found in environments like marshes, ruminant digestive tracts, and some deep aquatic sediments where oxygen is scarce. They play a crucial role in the carbon cycle, converting carbon dioxide into methane, a potent greenhouse gas.
Methanogens are also unique among the archaea in their energy metabolism. They reduce carbon dioxide to methane by a complex metabolic pathway known as methanogenesis.
