Gas·evolved in bioconversion of solid waste is:
Correct answer: A. Methane
- A. Methane
- B. Sulpher dioxide
- C. Nitrogen dioxide
- D. Ethane
Explanation
Solid wastes are biologically converted into value added products by physiological action of microorganisms. These processes occur under controlled environmental condition. It could be in the form of submerged fermentation or as solid-state fermentation technology. The gas released during this conversion is methane and carbon dioxide. Usually, carbon dioxide is released during aerobic conversion of solid waste while methane is released during anaerobic conversion of solid waste.
