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.
研究了粪肠球菌亚种液化亚种S-48菌株的抑制能力。该菌株产生一种广谱肽抗生素（AS-48），其特性已在其他地方进行了描述。诱变处理后从S-48中分离出的突变体揭示了另一种抑制物质，该物质在野生菌株中被掩盖。这种物质的蛋白质性质和有限的谱表明它是一种细菌素。
