| Abstract | ||
| Inhibitory effect of Lactobacillus plantarum was ٍstudied against Escherichia coli O157:H7 in minced beef , as well as the effect of some Spices ( Garlic , Cloves and Black Pepper ) was studied against this bacteria . Plate count method was used to estimate the viable cells of E. coli O157:H7 in the treated meat samples for incubation periods( 0 , 24 and 48) h. Results showed that Lactobacillus plantarum had inhibitory effect against E. coli O157:H7 , when reducing the number of cells after 24, 48 h., and reached to Zero after (24) h. As well as Spices in this study had inhibitory activity against E. coli O157:H7 .Garlic had the highest inhibitory effect compared with Cloves and Black Pepper. The synergistic inhibitory effect of the combination of Lactobacillus plantarum and Spices ( Garlic , Cloves and Black Pepper ) separately were studied against E. coli O157:H7 in the minced beef using the same method of counting . Results showed that the combination of Lactobacillus plantarum and spices had a synergistic inhibitory effect against E. coli O157:H7. The synergistic Inhibitory effect of Lactobacillus plantarum and garlic in (24)h. incubation period was higher than the effect of other spices. | ||
