The phenomenon of antibiosis (i.e., secre- tion of one microbe) was discovered by

Options

A. Pasteur
B. Babes
C. Vuilenin
D. Fleming

Answer

**Step-by-Step Solution:**

1. **Understanding Antibiosis**: Antibiosis refers to a biological interaction where one microorganism produces substances that are harmful to another microorganism. This interaction is often antagonistic, meaning one organism negatively affects the other.

2. **Identifying the Discoverer**: The question asks about the scientist who discovered the phenomenon of antibiosis. This requires knowledge of historical contributions to microbiology.

3. **Evaluating Options**: The options provided are:
- Louis Pasteur
- Babes
- Fleming
We need to determine which of these scientists is associated with the discovery of antibiosis.

4. **Analyzing Each Scientist**:
- **Louis Pasteur**: Known for his work on pasteurization and germ theory, but not specifically for antibiosis.
- **Babes**: Recognized for his research on antibiosis and the antagonistic interactions between microorganisms.
- **Fleming**: Known for discovering penicillin, which is a result of antibiosis, but he did not discover the phenomenon itself.

5. **Conclusion**: Based on the analysis, the correct answer is Babes, as he is credited with the discovery of the phenomenon of antibiosis.

**Final Answer**: The phenomenon of antibiosis was discovered by Babes.
