BIOXII10: MICROBES IN HUMAN WELFARE
343904
Select the correct answer i. A lot of cellulosic material present in the food of cattle is also present in the abomasum. ii. The biogas plant consists of a concrete tank (15-25 feet deep) in which bio-wastes are collected.
1 Only i is correct
2 Only ii is correct
3 Both are correct
4 None are correct
Explanation:
1]A lot of cellulosic material present in the food of cattle is also present in the rumen. In rumen, these bacteria help in the breakdown of cellulose and play an important role in nutrition of cattle. 2] The biogas plant consists of a concrete tank (10-15 feet deep) in which bio-wastes are collected.

Methanogens are ______and they produce methane by ____respiration.
1 Archaebacteria, Anaerobic
2 Archaebacteria, Aerobic
3 Cyanobacteria, Anaerobic
4 Cyanobacteria, Aerobic
Explanation:
Methanogens are Archaebacteria and produce methane by Anaerobic respiration. One such common bacterium is Methanobacterium which also found in the anaerobic sludge during sewage treatment.

Select the correct statements from the following
1 Activated sludge - sediment in settling tanks of sewage treatment plant is a rich source of aerobic bacteria.
2 Biogas to produced by the activity of virus on animal waste
3 Methanobacteria is an aerobic bacterium found in rumen of cattle
4 Bio-gas, commonly called gobar gas, is pure methane
Explanation:
Methanobacterium are anaerobic organisms. Biogas refers to a mixture of different gases produced by the breakdown of organic matter in the absence of oxygen. Activated sludge-sediment in settlement tanks of sewage treatment plant is a rich source of aerobic bacteria. Biogas can be produced by anaerobic digestion with anaerobic bacteria.'Activated sludge- sediment in settlement tanks of sewage treatment plant is a rich source of aerobic bacteria'.

Select the correct statement from the following:
1 Methanobacterium is an aerobic bacteria found in the rumen of cattle.
2 Biogas is produced by the activity of aerobic bacteria
3 Biogas is pure methane.
4 Activated sludge in sediment tanks is a rich source of aerobic bacteria.
Explanation:
Methanobacteriurn is an anaerobic bacteria found in the rumen of cattle. Biogas is produced by the activity of anaerobic bacteria. Biogas is not pure methane. Biogas is a mixture of gases. In addition to methane it also contains \(\mathrm{CO}_{2}\) and \(\mathrm{H}_{2}\).
