Choose correct combination of antibiotic production and microorganism:
Choose correct combination of antibiotic production and microorganism:
Show Hint
Erythromycin $\rightarrow$ S. erythraeus; the names are nearly identical, making them easy to pair.

- A & B Only
- A & D Only
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Concept
Many clinically important antibiotics are secondary metabolites produced by specific species of the genus Streptomyces.
Step 2: Meaning
The name of the antibiotic is often derived from the species name of the producing organism.
Step 3: Analysis
Amphotericin B (A) is produced by Streptomyces nodosus. Erythromycin (B) is produced by Saccharopolyspora erythraea (formerly Streptomyces erythraeus). Neomycin (C) is produced by Streptomyces fradiae, while Streptomyces venezuelae produces Chloramphenicol. Oxytetracycline (D) is produced by Streptomyces rimosus, while Streptomyces griseus produces Streptomycin.
Step 4: Conclusion
Only the combinations for Amphotericin B and Erythromycin are correct.
Final Answer: (C)
