Inhibition of food-borne pathogenic bacteria by bacteriocins from Lactobacillus gasseri.
Lactobacillus acidophilus group and a Lact. reuteri isolated from human faeces were examined for production of antimicrobial agents against 16 strains of six species of food-borne enteric pathogenic bacteria. Several strains of Lact. gasseri showed wide inhibitory activity against the tested bacteria. Gassericin A produced by Lact. gasseri LA39 was one of the most widely active bacteriocins. It was bactericidal without causing cell lysis.
