Large amount of protein can be produced in short span of time due to high rate of biomass production by :

Options

A. Methylophilus methylotrophus
B. Propionibacterium sharmanic
C. Agrobacterium tumifaciens
D. Saccharomyces cerevisiae

Answer

To solve the question regarding which organism can produce a large amount of protein in a short span of time due to a high rate of biomass production, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for an organism that can produce a large amount of protein quickly due to its high biomass production rate. This implies we need to identify an organism known for rapid growth and protein synthesis.

2. **Identifying Candidates**: The transcript mentions several organisms:
- Methylophilus methylotropus
- Propionibacterium shermanii
- Agrobacterium tumefaciens
- Common yeast (Saccharomyces cerevisiae)

3. **Analyzing Each Candidate**:
- **Methylophilus methylotropus**: This is a bacterium known for its ability to produce single-cell protein (SCP) efficiently. It utilizes methanol as a carbon source and has a high growth rate, leading to significant biomass and protein production.
- **Propionibacterium shermanii**: This bacterium is primarily involved in the fermentation process to produce Swiss cheese and does not focus on protein synthesis.
- **Agrobacterium tumefaciens**: This bacterium is known for its role in plant tumor induction and is not associated with high protein production.
- **Common yeast (Saccharomyces cerevisiae)**: While it is used in fermentation (like bread making), it does not have the same rapid biomass production capabilities as Methylophilus methylotropus.

4. **Conclusion**: Based on the analysis, Methylophilus methylotropus is the organism that can produce a large amount of protein in a short span of time due to its high rate of biomass production.

5. **Final Answer**: The correct answer is **Methylophilus methylotropus**.
