Abstract

The aim of the present study was to determine the probiotic potential of the lactic acid bacteria Lactobacillus plantarum KCC-24 (L. plantarum KCC-24), that was isolated and characterized from Italian
ryegrass (Lolium multiflorum) forage. The following experiments were performed to assess the probiotic
characteristics such as antifungal activity, antibiotic susceptibility, resistance to low pH, stimulated
gastric juice and bile salts, proteolytic activity, auto-aggregation, cell surface hydrophobicity, and in vitro
antioxidant property. The isolated L. plantarum KCC-24 exhibited significant antifungal activity against
the various fungal strains of Aspergillus fumigatus (73.43%), Penicillium chrysogenum (59.04%), Penicillium
roqueforti (56.67%), Botrytis elliptica (40.23%), Fusarium oxysporum (52.47%) and it was susceptible to
numerous antibiotics, survived in low pH, was resistant to stimulated gastric juices and bile salts (0.3% w/
v). Moreover, L. plantarum KCC-24 exhibited good proteolytic activity. In addition L. plantarum KCC-24
showed potent antioxidant and hydrogen peroxide resistant property. In conclusion, the isolated
L. plantarum KCC-24 exhibited several characteristics to prove it's excellent as a potential probiotic
candidate for developing quality food for ruminant animals and human.
