摘要:This study was undertaken to determine of antibacterial activities of different Lactobacilli strains (104 strains L. sake , 9 strains L. curvatus , 4 strains L plantarum ) isolated from Turkish fermented sucuk, against to L. monocytogenes and S. aureus. The antibacterial activities of lactobacilli species were determined with agar spot test and agar well diffusion test. For the analysis results, 18 of L . sake strains, 3 of L. curvatus strains and 2 of L. plantarum strains and 2 of L. plantarum strains, as tested, were formed inhibition zone against to L. monocytogenes in agar spot test, although 7 of L sake , 1 of L. curvatus and 1 of L plantarum strain was formed inhibition zone in the agar well diffusion test. In agar pot test, 8 of L sake and one of L. curvatus and L plantarum strains were formed inhibition zone against to S . aureus , while in the agar well diffusion test, 4 of L . sake strains were formed inhibition zone but, L. curvatus and L. plantarum stains were not formed inhibition zone. As a conclusion, antibacterial activities of lactobacilli species were variable both in species and in strains, therefore, it was suggested that bacteriocin and/or bacteriocin-like metabolites formed by lactobacilli should be used as a starter culture for controlled the growth of L. monocytogenes and S. aureus in the fermented sausages producing, after necessary tests were applied.
