Abstract


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.
