Distribution of pathogen inhibition in the Lactobacillus isolates of a commercial probiotic consortium.
Pure strains of Lactobacillus ssp. isolated from a commercial probiotic consortium were checked in a double layer solid medium for their inhibition activities against selected pathogenic bacteria including serotypes of Listeria monocytogenes, Escherichia coli and Salmonella. The antagonistic properties of the Lactobacillus strains may be related to the production of bacteriocin-like compounds. All the pathogens tested were inhibited by one or a few strains of Lactobacillus, the best inhibition was observed against L. monocytogenes but the inhibition was also satisfactory against E. coli, Salm. typhimurium and Salm. enteritidis.
