Lactic acid bacteria and bifidobacteria were isolated from the samples of dry microbial substance "Vivolac" and identified. The lactic acid bacteria were identified as Lactobacillus acidophilus. L. delbrueckii subsp. bulgaricus, L. paracasei. Bifidobacteria belonged to the species Bifidobacterium animalis. Manifestation of biological activity of all studied strains was investigated. It was shown, that adhesive activity of the studied strains depended on the genus of the strain: lactobacilli manifested medium adhesiveness to buccal epithelium (medium adhesive index 2.07-2.26), bifidobacteria manifested high adhesiveness (medium adhesive index 4.11-4.76). Antagonism against pathogenic and opportunistic reference strains was manifested to a greater extent to Pseudomonas aeruginosa. Lactobacilli and Bifidobacteria were resistant to aminoglycosides. Sensitivity of the studied strains to antibiotics did not depend on the genus and species of microorganism. Lactobacillus and Bifidobacterium strains were capable to survive in gastric juice and at different concentration of bile, which is promising for development of probiotic preparations on the basis of these strains. |
