What is a potential application of bacteriocins?

• A. Energy sources
• B. Antibiotic replacement
• C. Regulatory molecules
• D. Signal transduction inhibitors

Answer: (B)

Bacteriocins are antimicrobial peptides produced by bacteria that specifically target and inhibit or kill other bacteria. Because of this activity, they are being explored as potential antibiotic replacements, offering targeted antimicrobial action and the possibility of fewer disruptions to beneficial microbes compared with broad-spectrum antibiotics. They can be particularly useful against strains resistant to traditional drugs, though their practical use depends on achieving an appropriate spectrum, stability, and safety in the host. The other options don’t fit because bacteriocins are not energy sources, they are not primarily regulatory molecules that control gene expression, and they do not mainly function as inhibitors of signal transduction; their primary role is to directly inhibit or kill competing bacteria.
