Biogas production is carried out by

Options

A. Thermoacidophiles
B. Mathanogens
C. Halophiles
D. Luminants

Answer

**Step-by-Step Solution:**

1. **Understanding Biogas**:
- Biogas is a mixture of gases produced by the breakdown of organic matter in the absence of oxygen. The primary components of biogas are methane (CH4) and carbon dioxide (CO2).

2. **Identifying the Process**:
- The production of biogas occurs through anaerobic digestion, where microorganisms break down organic materials without oxygen.

3. **Analyzing the Options**:
- **Thermoacetophiles**: These are bacteria that thrive in high-temperature environments, such as hot springs. They are not involved in biogas production.
- **Methanogens**: These are a specific group of bacteria that produce methane as a metabolic byproduct in anaerobic conditions. They are commonly found in the digestive tracts of ruminant animals (like cows) and are crucial for biogas production.
- **Halophiles**: These organisms thrive in high-salt environments and are not related to biogas production.
- **Luminants**: This term generally refers to organisms that produce light and does not relate to biogas production.

4. **Conclusion**:
- The correct answer is **Methanogens** because they are the microorganisms responsible for producing methane in anaerobic conditions, which is a major component of biogas.

**Final Answer**: Biogas production is carried out by **Methanogens**.
