ABSTRACT
Objective:
To study the probiotic properties of 12 selected strains of lactobacilli.Methods:
The probiotic properties of 12 selected strains of lactobacilli were investigated for their resistance to pH 2.5 and 0.3% oxgall,their adhesion to Caco-2 cells and antimicrobial activity against enteric pathogenic bacteria.Results:
The 12 strains all showed relatively high resistance to acid and bile salt and varied antimicrobial activities against pathogenic bacteria of intestinal infection.Lactobacillus johnsonii JCM1022 exhibited a broad inhibitory effect on enteric pathogenic bacteria,especially on enteropathgenic E.coli and Salmonella enteritidis,while Lactobacillus reuteri JCM1081 possessed a high activity of adhesion to Caco-2 cells(495.07?80.03).Conclusion:
Among the 12 strains,Lactobacillus johnsonii JCM1022 and reuteri JCM1081 are qualified candidates for clinical application.
