Question

What is the group of bacteria found in both the rumen of cattle and sludge of sewage treatment?

Answer 1

Hint: Anaerobic bacteria play an essential role in the treatment of wastewater. They are in charge of sewage sludge methane fermentation, which aids in the breakdown of macromolecular organic waste into simpler molecules. Bacteria in the rumen aid in the digestion of cellulose and play an essential role in cow nutrition. These bacteria in the rumen also produce methane and therefore, dung of cattle produce lots of methane gas.

Complete answer:
Methanogen is a bacterial genus found in both cow rumen and sewage treatment sludge.
The rumen (a portion of the stomach) of cattle contains Methanobacterium which helps in the breakdown of cellulose.
Microorganisms known as methanogens generate methane as a metabolic byproduct in hypoxic environments. They're prokaryotic and belong to the archaea kingdom. They're prevalent in wetlands, where they cause marsh gas, and in the digestive systems of animals like ruminants and many people, where they cause the methane content of belching in ruminants and flatulence in humans.
Methanogens are either coccoid (spherical) or bacilli in form (rod shaped). Despite the fact that all known methanogens belong to the Archaea phylum, there are over fifty identified species of methanogens that do not form a monophyletic group. The majority of them are anaerobic microbes.

Note:
Methanogenesis is an anaerobic respiration process that produces methane as a byproduct. Methanogenesis is an anaerobic respiration process that employs oxidized carbon as a terminal electron acceptor, such as\[C{O_2}\] . As a result, methanogens thrive in environments where other electron acceptors, such as\[{O_2},{\text{ }}N{O_3}^-,{\text{ }}F{e^{3 + }},{\text{ }}and{\text{ }}S{O_4}^{2-}\] , are scarce. Two of such environments are the digestive tracts of ruminants and the sludge of sewage treatment plants.
