Lactobacillus reuteri LA 6, isolated from infant faeces, produced an antimicrobial agent active against Lactobacillus acidophilus JCM 2125, Lactobacillus delbrueckii subsp. bulgaricus JCM 1002 and Lactobacillus delbrueckii subsp. lactis JCM 1148 and JCM 1248. The agent was sensitive to proteolytic enzymes and retained activity after heating at 100°C for 20 min. This agent was a bacteriocin and has been designated as reutericin 6. Reutericin 6 exceeds 200 kDa as determined by ultrafiltration studies. Activity against sensitive cells was both bacteriocidal and bacteriolytic.
