Fifteen Lactobacillus strains were characterized for probiotic properties. Of these, 13 of the strains were Lactobacillus plantarum. L. acidophilus and L. pentosus were also included as controls. Among the several requirements, tolerance to acid and bile salts, ability to ferment fructooligosaccharides (FOS), beta-galactosidase activity and susceptibility to antibiotics were studied. Acid-tolerant isolates were L. plantarum HU, L. plantarum NCIMB 1193, L. plantarum 80, L. plantarum DSM 20174, L. plantarum DSM 20246, L. plantarum 37, and L. acidophilus ATCC 4356. Acid- and bile-tolerant isolates were L. plantarum 80, L. plantarum DSM 20174, L. plantarum DSM 20246, L. plantarum 37, L. plantarum HU, and L. acidophilus ATCC 4356. Eight of the strains had the ability to ferment FOS. These were, L. plantarum 80, L. plantarum DSM 20174, L. plantarum DSM 20246, L. plantarum NCIMB 1193, L. plantarum 37, L. plantarum 73, and L. plantarum HU. Strains L. plantarum 80, and L. plantarum 37 are highly resistant to antibiotics tested. L. plantarum NCIMB 1193, and L. pentosus had the highest beta-galactosidase activities. According to the obtained results, L. plantarum 37 L. plantarum 80, L. plantarum NCIMB 1193, and L. plantarum HU were found to be the most promising strains as probiotics.
