Genetic stability of the antagonistic character of Enterococcus faecalis ssp. liquefaciens and the detection of a new inhibitory bacteriocin-like substance
Abstract
The inhibitory capacity of strain S-48 of Enterococcus 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.
