Group of bacteria used in biogas production is

Options

A. eubacteria
B. organotrophs
C. methanotrophs
D. methanogens

Answer

**Step-by-Step Solution:**

1. **Understanding Biogas:**
- Biogas is a mixture of gases produced by the breakdown of organic matter. It primarily consists of methane, carbon dioxide, and small amounts of other gases.

2. **Anaerobic Breakdown:**
- The production of biogas occurs in an anaerobic medium, meaning it takes place in the absence of oxygen. This is crucial for the types of bacteria involved in this process.

3. **Identifying the Bacteria:**
- The bacteria responsible for the anaerobic breakdown of organic matter can be categorized into different groups. The two main types involved in biogas production are:
- Acetogens: These bacteria convert organic matter into acetic acid.
- Methanogens: These are the bacteria that specifically produce methane from the breakdown of organic matter.

4. **Conclusion:**
- Since the question asks for the group of bacteria used in biogas production, the correct answer is **Methanogens**, as they are the methane-forming bacteria that play a key role in the production of biogas.

5. **Final Answer:**
- The group of bacteria used in biogas production is **Methanogens**.
