| Abstract: | The inhibitory capacity of strain S-48 ofEnterococcus faecalis ssp.liquefaciens was studied. The strain produces a broad-spectrum peptide antibiotic (AS-48) that has been characterized elsewhere. The isolation
of mutants from S-48 after mutagenic treatment revealed another inhibitory substance which remained masked in the wild strain.
The protein nature and restricted spectrum of this substance points to its being a bacteriocin (Bc-48). |
