For retting of jute, the fermenting microbe is

Options

A. Methanophilic bacteria
B. Clostridium butylicum
C. Helicobacter pylori
D. Streptococcus lactis

Answer

To answer the question "For retting of jute, the fermenting microbe is," we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Process of Retting**:
- Retting is a process used to separate the fibers from the stem of plants like jute. It involves the action of microbes that break down the pectin and other substances holding the fibers together.

2. **Identify the Microbes Involved**:
- The question provides options for potential microbes involved in the retting process. We need to evaluate each option to determine which one is responsible for retting jute.

3. **Evaluate Each Option**:
- **Option 1: Methanophilic Bacteria**: These bacteria are primarily found in the digestive systems of ruminants and are not involved in the retting process.
- **Option 2: Clostridium butylicum**: This bacterium is known for producing butyric acid and is involved in the retting of jute. It helps in breaking down the plant material, making it the correct choice.
- **Option 3: Helicobacter pylori**: This bacterium is associated with peptic ulcers in humans and is not related to retting.
- **Option 4: Streptococcus lactis**: This bacterium is involved in dairy fermentation processes and does not play a role in retting jute.

4. **Conclusion**:
- After evaluating all options, we conclude that **Clostridium butylicum** is the fermenting microbe responsible for the retting of jute.

### Final Answer:
The fermenting microbe for the retting of jute is **Clostridium butylicum**.
