The guts of cow and buffalo possessMethanogens (archaebacteria) present in the gut of cows and buffaloes are responsible for the partial digestion of cellulose and produce methane.
2014 AIPMT 1 question
-
Archaebacteria differ from eubacteria in:Archaebacteria have a different cell wall structure and unusual branched-chain lipids in their cell membrane, which lets them survive in extreme conditions.

Organisms called methanogens are most abundant in aMethanogens are archaebacteria that are strict anaerobes and produce methane.
They live in the gut (rumen) of ruminant animals such as cows and buffaloes, where they help in the digestion of cellulose.
The dung of cattle (gobar) is therefore rich in these bacteria, and they produce methane (biogas) from it.
So they are most abundant in a cattle yard; they are also common in marshy areas and flooded paddy fields.
Hot springs are the habitat of thermoacidophiles, another group of archaebacteria.
Hence methanogens are most abundant in a cattle yard.
