Methanogenic bacteria are not found in:
1 Rumen of cattle
2 Gobar gas plant
3 Bottom of water-logged paddy fields
4 Activated sludge.
Explanation:
Activated sludge contains aerobic bacteria. It is sent to the digester where it is acted upon by methanogens.

Which of the following bacteria is present in the rumen of cattle?
1 Rhizobium
2 Azolla
3 Methanobacterium
4 Cyanobacteria
Explanation:
Methanogens, are the anaerobic bacteria, which breakdown cellulosic material to produce methan, \(\mathrm{CO}_{2}\) and \(\mathrm{H}_{2}\). These are found in the anaerobic sludge in sewage treatment plants and rumen(a part of stomach) of cattle.

Methanogens belong to
1 Archeabacteria
2 Eubacteria
3 Mycoplasma
4 Cyanobacteria
Explanation:
Biogas producing obligate anaerobe, methanogens belong to domain Archaebacteria.
