Question

Supply of oxygen to the biogas plant will have ?

• A. Positive effect
• B. Negative effect
• C. No effect
• D. None of the above

Answer 1

The correct option is B Negative effect

Supply of oxygen to the biogas plant will have -ve effect. Because the entire process is anaerobic, which does not favour the presence of oxygen.

Biogas typically refers to a mixture of different gases produced by the breakdown of organic matter through anaerobic bacteria such as Methanogen that can act in the absence of Oxygen only. in the presence of Oxygen, they will not be able to function and causes negative effects.

Thus, the correct answer is option B.
