Which organism produces gentamicin?

Which organism produces gentamicin?

• A. Micromonospora
• B. Streptomyces
• C. Penicillium
• D. Bacillus

Answer: (A)

Gentamicin is an aminoglycoside antibiotic produced by a soil actinomycete known as Micromonospora, historically linked to Micromonospora purpurea. This genus is specifically associated with gentamicin biosynthesis, setting it apart from other common antibiotic producers. Streptomyces is famous for many antibiotics (like streptomycin), Penicillium for penicillin, and Bacillus for bacitracin or polymyxin, but none of those are the typical producers of gentamicin. Therefore Micromonospora is the best answer.
