Also the chemical components of the EOs were identified. Based on the results. Also, in all EOs, the antifungal index increased with increasing the concentration, but the effect of time was different; with the time of expose, the antifungal index increased in ZEO, but decreased in the two other EOs. Furthermore, due to the results of optimization, the CEO with 120.133μL.L-1 and 301.152μL.L-1 concentrations and 24.380 and 22.802h expose time and SEO with 224.697μL.L-1 and 550.803μL.L-1 concentrations and 23h expose time, for 50 and 100% Inhibit Mycelial Growth, respectively, have the most and least effect on inhibiting mycelial growth of Rhizopus stolonifer. Also, the results of this study showed that the response surface method can be considered as a suitable and accurate method for modeling and optimizing the antifungal activity of these EOs.
