Which of the following statements about methanogens is not correct ?a...
Incorrect Statement: They grow aerobically and breakdown cellulose-rich food.
Explanation:
Methanogens are a type of microorganisms that produce methane gas as a metabolic by-product under anaerobic conditions. They are found in various environments such as wetlands, swamps, sewage treatment plants, and the digestive tracts of ruminants, where they play an important role in the degradation of organic matter. Here are some correct statements about methanogens:
• They produce methane gas: Methanogens are unique microorganisms that use carbon dioxide or other simple organic compounds as an electron acceptor and hydrogen gas as an electron donor to produce methane gas. This process is called methanogenesis.
• They can be used to produce biogas: Methanogens are used in anaerobic digestion systems to produce biogas from organic waste such as food scraps, manure, and wastewater. Biogas is a renewable energy source that can be used for heating, electricity generation, or transportation.
• They are found in the rumen of cattle and their excreta: Methanogens are present in the rumen of cattle, sheep, and other ruminants, where they help to break down complex carbohydrates in the diet into simpler compounds that can be absorbed by the animal. They are also found in the manure and other excreta of these animals.
In conclusion, option D is the incorrect statement as methanogens are strictly anaerobic microorganisms that cannot grow in the presence of oxygen. Additionally, they do not breakdown cellulose-rich food aerobically as cellulose is broken down into simpler compounds by aerobic microorganisms such as fungi and bacteria.
