Anaerobic digestion is a collection of a process by which microorganism break down biodegradable material in the absence of oxygen and some of these processes are used in the waste Industries to manage the waste. Primary sludge is a result of the capture of suspended solids and organics materials. In the primary process of waste management, the material is treated in a variety of ways. During the biological treatment of the waste a part of activated sludge is used as inoculum and they are passed into the last tank which is known as anaerobic sludge digester. The microorganism present in the sludge gets killed.
Which of the following is correct about biogas?
-
Methane gas is produced along with ethyl alcohol by methanogen
-
Methanogens acts on cellulose and release biogas
-
Biogas is produced by thunder and lightening
-
Maximum gas found in biogas is $CO _2$
-
Methanogens are present in the rumen of cattle that is present in dung as well. Methanogens acts on the cellulose content of the and It helps in the production of methane gas that is a component of biogas.
- Hence Methanogens acts on cellulose and release biogas is a correct statement.
- So, the correct answer is 'Methanogens acts on cellulose and release biogas'.
