What is methanogen domain?

Methanogens are a group of microorganisms that belong to the domain Archaea. They are unique in their ability to produce methane as a metabolic byproduct during the anaerobic digestion of organic matter. Methanogens play a crucial role in various environments, including wetlands, the digestive tracts of ruminants, and anaerobic digesters, contributing to the global carbon cycle. Their metabolic processes are important for energy production and can impact greenhouse gas emissions.
