Abstract: Microbial resistance to antibiotics, especially among staphylococcal strains is a major threat to public health. The aim of this study was to assessment of anti-bacterial effect of monolaurin on Staphylococcus aureus and Escherichia coli. In this study, colonies are cultured in nutrient broth media and incubated at 37°C for 24 h. Then, tubes chilled in the laboratory environment. Three different concentrations of monolaurin prepared and added to culture media containing BHI agar media. Then, these plates are incubated 37°C for 24 h and prepared to count. After 24 h, plates were out and colonies are counted and multiply in 100. Data were analyzed by SPSS software Version 16. Based on data revealed that at 60°C and more. There was no observed any microorganisms colonization either Staphylococcus aureus or Escherichia coli but at the 55°C, there was observed more decrease in colonization than 50°C. This finding suggests that chilling is one of the most important ways to maintenance of foods. The results also showed that temperature also increases inhibitory properties of monolaurin. The results of the study suggest that monolaurin have anti-bacterial effect against Staphylococcus aureus and Escherichia coli.
