Vedclass · Answer

(B) The correct answer is $B$. During the process of sewage treatment,anaerobic sludge digesters are used to decompose organic matter. Microbial activity in these digesters depends on the specific microbes and the organic substrates present. Methanogens are a group of anaerobic bacteria that act on cellulosic material to produce large amounts of methane $(CH_4)$ along with carbon dioxide $(CO_2)$. Additionally,other anaerobic bacteria present in the sludge produce gases such as hydrogen sulphide $(H_2S)$ and ammonia $(NH_3)$. Therefore,the mixture of gases produced in anaerobic sludge digesters typically includes methane,hydrogen sulphide,and carbon dioxide.
