The effect of Zataria multiflora Boiss Essential oil on the growth and citrinin production of Penicillium citri num in culture media and cheese

摘要

The effect ofZataria multifloraBoiss Essential oil (EO) on the growth, spore production, and citrinin production ofPenicellium citrinumPTCC 5304 in the culture media as well as Iranian ultra-filtered white cheese in brine was investigated. Radial growth and spore production on the potato dextrose agar (PDA) were effectively inhibited by EO in a dose-dependent manner. At 200?ppm, the radial growth and sporulation declined by 92% and 100%, respectively. The growth was completely prevented at 400?ppm of EO on PDA and the minimum fungicidal concentration (MFC) of the oil was estimated at 400?ppm. Furthermore, theZataria multifloraalso significantly suppressed the mycelial growth and citrinin production in broth medium at all investigated concentrations (P?
