Which type of bacteria are responsible for production of biogas?

Options

A. Halophiles
B. Thermoacidophiles
C. Methanogens
D. BGA

Answer

**Step-by-Step Solution:**

1. **Understanding Biogas Production**: Biogas is a renewable energy source produced through the breakdown of organic matter by microorganisms in anaerobic conditions (absence of oxygen).

2. **Identifying the Types of Bacteria**: There are various types of bacteria, but not all are involved in biogas production. The main types mentioned are:
- Halophiles: Bacteria that thrive in high-salt environments.
- Thermoacidophiles: Bacteria that live in hot and acidic environments.
- Methanogens: Bacteria that produce methane as a metabolic byproduct in anaerobic conditions.
- BGA (Blue Green Algae): Photosynthetic organisms, not bacteria involved in biogas production.

3. **Focusing on Methanogens**: Among the types listed, methanogens are specifically known for their role in the production of biogas. They are found in the digestive systems of ruminant animals (like cows and buffaloes) and in environments where organic matter is decomposed anaerobically.

4. **Conclusion**: Therefore, the type of bacteria responsible for the production of biogas is **Methanogens**.

**Final Answer**: Methanogens are the bacteria responsible for the production of biogas.
