Determination of Metabolic and Antimicrobial Activities of Lactobacillus plantarum Strains Isolated from Traditional Fermented Pickles

Abstract

Lactobacillus species are more effective on the maturation of pickles. In this study, acid and H₂O₂ rates which were made by 22 strains of Lactobacillus plantarum izolated from tradional pickles were 0.48-0.87% and 0.77-2.68 µg mL^-1. General inhibition activities of strains and inhibition activities of bacteriocin and/or materials such like bacteriocin were determined by agar diffusion method, against test microorganisms. The plasmid profiles of Lactobacillus plantarum were determined. It was observed that Lactobacillus plantarum strains were produced bacteriocin or inhibitor material such like bacteriocin and these materials affected to some test microorganisms. Additionally it was determined that L. plantarum strains produced various metabolic products at different rates and they showed inhibitory affect at different rates against test microorganisms.
