- Abstract
This study was conducted to evaluate the probiotic properties and antioxidant activities of lactic acid bacteria strains including Levilactobacillus brevis KU15147 isolated from kimchi to determine their potential as a probiotic. The tolerance of all strains to gastric acid and bile salts was more than 90%. The strains did not produce a β-glucuronidase and survived following treatment with gentamicin, kanamycin, streptomycin, and ciprofloxacin. L. brevis KU15147 showed greater adhesion activity to HT-29 cells (6.38%) and its antioxidant activities were higher than those of other tested strains, showing values of 38.56%, 22%, and 23.82% in DPPH, ABTS, and β-carotene bleaching assays, respectively. Additionally, the relative expression intensities of induced nitric oxide synthase and tumor necrosis factor-α of L. brevis KU15147 were greater than those of other strains, suggesting that this strain can be applied in the health food or pharmaceutical industry as a novel probiotic strain.
