Background: A large number of plants are used for treatment of diseases because of their antimicrobial activities. This study aims to investigate the antimicrobial effects of some plants on the food pathogenic bacteria. Methods: Plant extracts were obtained using the rotary system, the minimum inhibitory concentration (MIC) by diluting method against bacteria was determined. Results: Results showed that the lowest MIC of the Peganum harmala was 3.1 ppm and the highest inhibitory concentration was 6.25 ppm for inhibiting the Vibrio cholerae. |
