Objective: finding new antibacterial substances to fight against pathogenic microbes, due to raised antibiotic resistance the International Scientific Association for Probiotics and Prebiotics (ISAPP) defined a postbiotic as “a preparation of inanimate microorganisms and/or their components that confer a health benefit on the host. Materials and methods: postbiotics were prepared in a liquid culture medium of Mueller Hinton broth in a shaker incubator. Finally, the effect of these postbiotics on Staphylococcus aureus was determined through MIC and MBC tests, as well as through the Agar disk diffusion and Agar well diffusion method by determining the diameter of the halos. Results: The results showed that the average MIC value of Pediococcus acidilactici postbiotics on this bacterium was 31.25 μl/ml and the Average MBC was 62.55 μl/ml. Disks diffusion with 105, 125, and 145 microliters of Pediococcus acidilactici formed halos with diameters of 8.33±0.58a, 10.00±1.00 a, and 11.33±1.53 b millimeters with p-value of 0.043. in the well diffusion method Pediococcus acidilactici postbiotics in concentrations of 125, 135, 145, and 155 microliter formed halos with a diameter of 22.00±1.00 a, 26.00±1.00 b, 26.67±0.58 b, and 29.33±0.58 c millimeters around the well with the p-Value of 0.001. Conclusion: The postbiotics of Pediococcus acidilactici inhibited the growth of Staphylococcus aureus (ATCC 13813).
