Question:
The biogas production starts falling very steeply when the temperature is below
The biogas production starts falling very steeply when the temperature is below
Show Hint
Low temperature reduces microbial activity, so biogas production decreases sharply below about \(20^\circ C\).
Updated On: May 4, 2026
- \(35^\circ C\)
- \(30^\circ C\)
- \(25^\circ C\)
- \(20^\circ C\)
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Biogas production is a microbial process.
Step 2: Methanogenic bacteria are responsible for methane formation in biogas plants.
Step 3: These bacteria work best within a suitable temperature range.
Step 4: If temperature becomes too low, microbial activity decreases rapidly.
Step 5: Biogas production starts falling very steeply when temperature goes below: \[ 20^\circ C \] \[ \boxed{20^\circ C} \]
