Özet

Inhibitory activity of 32 strains of lactic acid bacteria isolated from raw milk was evaluated for their ability to inhibit some hazardous microbes. The isolates consisted of the genera Lactobacillus (43.75%), Pediococcus (28.12%), Streptococcus (15.62%), and Leuconostoc (12.50%). All the strains tested inhibited one or more indicator strains. Yersinia enterocolitica was inhibited by the all lactic acid bacteria. Of the lactic acid bacterial isolates, 93.75% exhibited inhibitory activity against Listeria monocytogenes. The indicator strains belonging to the same genus, Bacillus subtilis and B. cereus, were inhibited at the same level by 87.50% of the test strains. Staphylococcus aureus was also inhibited by 81.25% of the test strains, whereas Str. faecalis was inhibited at the lowest level by 62.59% of the lactic acid bacteria isolated from raw milk.
