EFFECT OF ESSENTIAL OILS OF ANIBA ROSAEODORA, LAURUS NOBILIS, SYZYGIUM AROMATICUM, MENTHA PIPERITA AND LAVANDULA ANGUSTIFOLIA ON GROWTH OF MICROMYCETES

Abstract

Aim: to investigate the effect of essential oils (EOs) of rosewood Aniba rosaeodora Ducke, laurel Laurus nobilis L, clove Syzygium aromaticum (L.) Merr. &L.M. Perry, mint Mentha piperita L. and lavender Lavandula angustifolia Mill. on the mycelial growth and spore germination of Alternaria alternata (Fr.) Kiessl, Aspergillus ochraceus G. Wilh. and Penicillium chrysogenum Thom was performed. Methods: tested fungi were isolated from contaminated carrot seeds, stored tomatos and spikelets of wheat. Agar diffusion method and modified agar diffusion and vapor assay were used. Results: EOs of rosewood, clove and laurel exerted a potent dose dependent inhibitory effect on mycelial growth of tested fungi. Mycelium of micromycetes was more sensitive to the fungistatic action of EOs than their conidia. This EO at the concentrations of 1.5μl/ml caused prolonged total inhibition of mycelial growth and spore germination of all tested fungi. Conclusion: these findings support the potential use of EO of Aniba rosaeodora as well as EOs of Laurus nobilis and Syzygium aromaticum for natural food protection against mold infestation.
