Fourteen of 200 Lactobacillus isolates from African fermented foods, viz. 'wara', 'kenkey', 'ugba', 'ogi', 'kunuzarki', 'fufu' and 'iru' were found to produce bacteriocins against L. plantarum and only three bacteriocinogenic isolates inhibited some of the food pathogens. Plasmid analysis of the 14 bacteriocin-producing lactobacilli showed that only 5 isolates harbored plasmids ranging in size from 3.1 to 55.5 kb.
从非洲发酵食品“wara”、“kenkey”、“ugba”、“ogi”、“kunuzarki”、“fufu”和“iru”中分离出的200株乳酸菌中，有14株被发现能产生针对植物乳杆菌的细菌素，只有3株产细菌素的分离株能抑制一些食品病原体。对这14株产细菌素的乳酸菌进行质粒分析表明，只有5株分离株含有大小在3.1至55.5 kb之间的质粒。
