Light microphotographs of A. flavus ATCC-16013 mycelium growing on AS without or with H. suaveolens essential oil (20 µL/mL) during 7 days of incubation at 25 – 28 °C. (A) Control conidial head of A. flavus, large and radiated, development of vesicle on conidiophore, conidia clearly visible, Bar 100 µm. (B) control magnification of single vegetative hyphae of A. flavus, regular growing hyphae, clear visualization of a homogenous cytoplasm and homogeneous structure, Bar 100 µm. (C) Modifications of the conidial head of A. flavus induced by 20 µL/mL of H. suaveolens essential oil, showing clear reduction in conidiation, Bar 100 µm. (D-E) Hyphae with loss of pigmentation conidiation, anomalous structure, clear leakage of cytoplasm content and destruction of cell structure noted by disrupted hyphae integrity induced by 10 µL/mL of H. suaveolens essential oil, Bar 100 µm.
