[Study of probiotic properties of bacteriocinogenic Lactobacillus plantarum G3/3(13) strain]

Bacteriocinogenic culture Lactobacillus plantarum G3/3(13) was tested according to the basic requirements to probiotic strains. The reidentification of the strain was carried out using a set of methods including PCR. It was confirmed that the strain belongs to the species L. plantarum. The studied culture expressed antagonistic activity with respect to Enterococcus faecalis and E. faecium. The susceptibility test to 57 antibiotics of different groups showed that the strain was resistant to oxacillin, cefepyme, lomefloxacin, polymyxin, nalidixic acid and the antifungal antibiotics. High adhesive properties of the microorganism to the human epithelial cells (medium adhesion index was 4.6-5.6; microorganism adhesion index was 4.9-5.9) were shown. Obtained results allow to recommend L. plantarum G3/3(13) for the construction of probiotics.
