Open in App
Solution
The correct option is B Activated sludge
Introduction to methanogens
Methanogenic bacteria are anaerobic and therefore live in areas without oxygen. These bacteria are used in anaerobic digesters where they act on organic matter anaerobically converting it to a mixture of inflammable gases like methane, carbon dioxide, hydrogen etc.
Occurrence of methanogens
Methanogens are found in:-
1)Anaerobic sludge digesters
2)Rumen of cattle
Biogas
3)Warm water logged paddy fields
Activated sludge
Activated sludge contains flocs (aerobic bacteria and fungi) formed as a sediment during the aerobic treatment of sewage.
Final answer
(B) Activated sludge
