Vedclass · Answer

(A) Biogas is a methane-rich fuel gas produced by the anaerobic breakdown or digestion of organic matter (cellulosic material) with the help of methanogenic bacteria.Methanogens,such as $Methanobacterium$,are found in the anaerobic sludge during sewage treatment and in the rumen of cattle.These bacteria produce a mixture of gases,primarily methane $(50-70\%)$,carbon dioxide $(30-40\%)$,and traces of other gases like hydrogen,hydrogen sulphide,and nitrogen.Oxygen is not produced during this anaerobic process; in fact,it is inhibited by oxygen.Therefore,the correct products are methane $(I)$ and carbon dioxide $(II)$.

Methanogens,particularly $Methanobacterium$,grow anaerobically on cellulosic material and produce:
$I.$ Methane
$II.$ Carbon dioxide
$III.$ Oxygen
$IV.$ Ethane
Choose the correct option.
