Distribution of pathogen inhibition in theLactobacillusisolates of a commercial probiotic consortium

摘要

Pure strains ofLactobacillusssp. isolated from a commercial probiotic consortium were checked in a double layer solid medium for their inhibition activities against selected pathogenic bacteria including serotypes ofListeria monocytogenes, Escherichia coliandSalmonella.The antagonistic properties of theLactobacillusstrains may be related to the production of bacteriocin‐like compounds. All the pathogens tested were inhibited by one or a few strains ofLactobacillus,the best inhibition was observed againstL. monocytogenesbut the inhibition was also satisfactory againstE. coli, Salm. typhimuriumandSalm. enteritidi
