Which of the following bacteria is present in the rumen of cattle?

Detailed Solution for Test: Microbes in Production of Biogas (NCERT) - Question 3

Methanobacterium is found in the rumen (a part of the stomach) of cattle. A lot of cellulosic material is also available in the rumen. In rumen, these bacteria help in the breakdown of cellulose and play an important role in nutrition of cattle.

Which of the following statements is incorrect?
Detailed Solution for Test: Microbes in Production of Biogas (NCERT) - Question 5

Word antibiotic is a misnomer. Anti is a Greek word that means 'against', and bios means 'life', together they mean 'against life' (in the context of disease-causing organisms); whereas with reference to human beings, they are 'pro life' and not against. Flocs are masses of bacteria with interwoven fungal filaments which form mesh-like structures. Components of biogas are methane (50 70%); carbon dioxide (30-40%) and traces of hydrogen, nitrogen and H2S.

Biogas generation is a three-stage anaerobic digestion of animal and other organic wastes. Study the following flow chart and select the correct option for stages I, II and Ill. 
Detailed Solution for Test: Microbes in Production of Biogas (NCERT) - Question 7

In stage - I, anaerobic microorganisms bring about enzymatic breakdown of complex organic compounds into simple soluble compounds or monomers.
In stage - II, monomers are converted into organic acids by fermentation causing microbes.
In stage - Ill, organic acids are acted upon by methanogenic bacteria to produce biogas.
