Solution
Rumen
The rumen of cattle contain methanogens like Methanobacterium. These organisms are anaerobic bacteria that help in the breakdown of cellulose, thus helping the cattle to derive energy from raw plant material.
Sludge digesters
The activated sludge formed is fed into anaerobic sludge digesters where anaerobic bacteria like methanogens digest the microbes of the flocs. This process releases a mixture of gases, called biogas.
Final answer: Methanogens
The rumen of cattle contain methanogens like Methanobacterium. These organisms are anaerobic bacteria that help in the breakdown of cellulose, thus helping the cattle to derive energy from raw plant material.
