Extracellular vesicle packaging of a supercluster-encoded antimicrobial combination with enhanced potency against fungal biofilms

Co-packaging of candicidin and antimycin A in extracellular vesicles from a Streptomyces soil isolate is linked to enhanced potency against fungal biofilms.

• Why it matters: Specialized metabolites are usually studied as single soluble compounds, leaving how coordinated combinations are packaged, delivered, and act on biofilms unclear.
• What they did: The study reports EV co-packaging of two supercluster-encoded metabolite complexes and tests antimicrobial activity against fungal biofilms versus individual compounds.
• The result: While fungal biofilms are tolerant to individual compounds, the supercluster products show synergistic antimicrobial activity, and EV co-delivery yields simultaneous delivery with enhanced potency.
