Postharvest rot of pomegranate fruits due to fungal infections causes the loss of a significant amount of fruit. In this study, the antifungal effects of thymol on the growth of Aspergillus niger (A. niger) and Penicillium commune (P. commune) were investigated. Molecular sequence analysis of internal transcribed spacer (ITS) gene was used to identify fungal species. ITS of rDNA amplified by polymerase chain reaction (PCR), sequenced and after basic local alignment search, it was registered in GenBank database. The minimum inhibitory concentration (MIC) and minimum fungicidal concentration (MFC) of thymol for both fungi were 250 and 500μg mL-1, respectively. Scanning electron microscopy (SEM) in A. niger colony showed cell deformation due to destruction of the cell membrane and loss of cell wall strength at 250μg mL-1 after 168 h. Evaluation of P. commune cell morphology showed that thymol at 250μg mL-1 caused...
