摘要: In the present work we studied antifungal effect of eugenol and thymol on growth production citrinin from Penicillium citrinum (NRRL 2274 NRRL 2269) in culture media different Spanish cheeses (Arzua-Ulloa, Cebreiro San Simon). The rate was assessed by measuring colony diameters measured using a rapid semi-quantitative fluorometric technique confirmed RP-HPLC. A stronger inhibitory than evident. 200 microg/ml solid medium increased lag time up to 9 days, decreased growth. liquid medium, complete inhibition fungal observed. By contrast, only affected rate. Arzua-Ulloa cheese, fully inhibited growth, while cheese no observed for this compound. Regarding capacity inhibit mycotoxin 100 delayed until sixth day, after which limiting persisted. detected at concentration 150 eugenol, but 5 days case same concentration. neither nor prevented concentrations applied.
