उत्तर
Methanogenic bacteria are not found in activated sludge.
Explanation:
Methanogenic bacteria are not found in activated sludge because they can survive and function only under anaerobic (oxygen-free) conditions.
Activated sludge is an aerobic process, where oxygen is supplied for the breakdown of organic matter, so methanogens cannot grow there; they are instead found in anaerobic digesters used for sludge treatment.
