Methanogens belong to
Methanogens are a subgroup of archaebacteria, which are a group of bacteria that have been around for a very long time and flourish in harsh settings. When they are in anaerobic conditions, they generate methane as a byproduct of their metabolic processes. By gaining an understanding that methanogens are classified as archaebacteria, students are better able to correctly classify these organisms and distinguish the distinctive metabolic processes that they possess.
