NEET BIOLOGY

Detailed explanation-1: -Methanogens are present in the gut of several ruminant animals such as cows and buffaloes and they are responsible for the production of methane (biogas) from the dung of these animals.

Detailed explanation-2: -The primitive prokaryotes responsible for the production of biogas from the dung of ruminant animals include the methanogens.

Detailed explanation-3: -The Methanobacteria present in the organic waste decompose the waste and produce the mixture of gases known as biogas.

Detailed explanation-4: -Methanogens are the bacteria found in cattle dung (gobar) and in anaerobic sludge during sewage treatment. [1] They grow anaerobically on cellulosic material and produce a large amount of methane (main constituent of bio gas) along with CO2 and H2. Thus, methanogens are used in biogas production.

Detailed explanation-5: -It can be produced from the dung of ruminating animals. These animals have methanogens (microorganisms that produce methane) in their gut. These bacteria help in the digestion of cellulose. Anaerobic respiration allows these bacteria to create methane gas.
