Detectionn and activity of plantaricin OL15 a bacteriocin produced by Lactobacillus plantarum OL15 isolated from Algerian fermented olives.
Keywords:Bacteriocin, Inhibition, Lactic acid bacteria, Lactobacillus plantarum, Table olives
Lactobacillus plantarum OL15 previously isolated from Algerian fermented green olives produces antimicrobial conpounds in its culture medium. Inhibitory action against other strains of Lactobacillus, Lactococcus , and Propionibacterium was observed . Activity was completely or partially inactivated by proteolytic enzymes, stable at pH values ranging from 3.0 to 8.0, and heat stable even after autoclaving at 121 °C for 15 min. The bacteriocin activity was able to pass through cellulose membranes with 100,000 but not through 10,000 molecular weight cut-off.
