Question

Which of the following microbial sources is used for the production of antibiotic terramycin?

• A. Streptomyces erythreus
• B. Streptomyces venezuelae
• C. Streptomyces griseus
• D. Streptomyces aurifaciens

Hint:

Create a quick matching table in your notes for Microbes and their Products:
S. griseus $\rightarrow$ Streptomycin
S. venezuelae $\rightarrow$ Chloramphenicol
S. aurifaciens $\rightarrow$ Terramycin/Aureomycin

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
Antibiotics are potent secondary metabolites produced by certain microorganisms that inhibit the growth of other microbes.
The bacterial genus Streptomyces is heavily utilized as a major biological source of naturally occurring antibiotics.

Step 2: Key Formula or Approach:
Memorize the specific Streptomyces species and the corresponding antibiotics they produce according to the standard biology syllabus.

Step 3: Detailed Explanation:
Streptomyces erythreus is the microbial source for the antibiotic Erythromycin.
Streptomyces venezuelae is utilized for the production of Chloramphenicol.
Streptomyces griseus is widely known as the source of Streptomycin.
According to the officially prescribed state board curriculum, Streptomyces aurifaciens is explicitly cited as the microbial source for the antibiotic Terramycin.

Step 4: Final Answer:
Streptomyces aurifaciens is used for Terramycin production, making option (D) correct.
