Options

A. Penicillium species
B. Aspergillus species
C. Streptomyces species
D. Bacillus species

Answer

To solve the question about which microbe helps in providing the antibiotics erythromycin and chloramphenicol, we can follow these steps:

### Step 1: Identify the antibiotics
First, we need to recognize the two antibiotics mentioned in the question: erythromycin and chloramphenicol.

### Step 2: Understand the sources of antibiotics
Next, we should look into the sources of these antibiotics. Many antibiotics are derived from various microorganisms, including bacteria and fungi.

### Step 3: Review the options provided
The options given are:
1. Penicillium species
2. Aspergillus species
3. Streptomyces species
4. Bacillus species

### Step 4: Analyze each option
- **Penicillium species**: Known for producing penicillin, not erythromycin or chloramphenicol.
- **Aspergillus species**: Primarily associated with the production of citric acid and not these antibiotics.
- **Streptomyces species**: This is a genus of gram-positive bacteria known for producing a variety of antibiotics, including both erythromycin and chloramphenicol.
- **Bacillus species**: While some Bacillus species produce antibiotics, they do not produce erythromycin or chloramphenicol.

### Step 5: Conclusion
Based on the analysis, the correct answer is **Streptomyces species**, as it is the microbe responsible for producing both erythromycin and chloramphenicol.

### Final Answer:
**Streptomyces species** helps in providing the antibiotics erythromycin and chloramphenicol.
