Question

Match List-I with List-II 

Choose the correct answer from the options given below: 
 

• (A) - (I), (B) - (II), (C) - (III), (D) - (IV)
• (A) - (I), (B) - (III), (C) - (II), (D) - (IV)
• (A) - (I), (B) - (II), (C) - (IV), (D) - (III)
• (A) - (III), (B) - (IV), (C) - (II), (D) - (I)

Hint:

Associate key antibiotics with their source type. Penicillin \(\rightarrow\) *Penicillium* mold. Most "-mycin" antibiotics (like streptomycin, erythromycin) \(\rightarrow\) *Streptomyces* bacteria. Bacitracin \(\rightarrow\) *Bacillus*.

Answer 1

The Correct Option is D

Step 1: Introduction: Antibiotics are often natural products, specifically secondary metabolites from microbes, mainly fungi and bacteria (especially Actinobacteria). This question assesses knowledge of microbial sources for common antibiotics. Step 2: Breakdown: (A) Penicillin G: Produced by the mold Penicillium chrysogenum. Matches (III). (B) Gentamycin: Produced by the bacterium Micromonospora purpurea. Matches (IV). (C) Bacitracin: Produced by the bacterium Bacillus subtilis. Matches (II). (D) Cycloheximide: Produced by the bacterium Streptomyces griseus. Matches (I). Step 3: Solution: The correct matching: A-III, B-IV, C-II, D-I, which is option (4).
