Rapid detection method for bacteriocin and distribution of bacteriocin-producing strains in Lactobacillus acidophilus group lactic acid bacteria isolated from human feces.

A new screening method, using micro plate wells, was developed for detecting the bacteriocin producer in lactic acid bacteria. The method was applied for screening the bacteriocin producer in L. acidophilus group lactic acid bacteria isolated from human feces with 19 bacteria used as indicator strains. Of the 98 strains, 62 were finally selected as the bacteriocin producers, including 39 strains positive against at least one of food-borne pathogenic bacteria.
