Antifungal and Antimycotoxigenic Properties of Newly Synthesized Derivatives of Tetraketone
The effect of newly synthesized derivative 5-aryl-5-hydroxy-2-/aryl-(hydroxyimino/ethyl/-1-cyclohexanone, on growth and zearalenone accumulation by toxigenic mold Fusarium graminearum ZMPBF 1244 was studied in yeast extract-sucrose (YES) medium to determine the possible use of this compound as a mean of controlling zearalenone accumulation.Experiments were carried out in a stationary culture at temperatures of 10 and 20 oC, respectively, with and without "temperature shock" for 25 days. Mycelial dry weights were determined gravimetrically, and concentration of zearalenone (ZEA) were measured fluorodensitometrically using a Camag TLC Scanner.In experiments with a "temperature shock" and at pH 5.5, concentration of investigated derivative higher than 15.0 μ g x mL-1 of liquid medium completely inhibited growth and ZEA accumulation after 15 days of incubation at temperatures of 10 and 20 oC.Concentrations of 5.0 μ g x mL-1 and 10.0 μ g x mL-1 partially inhibited growth and decreased ZEA accumulation by 45% and 70%, respectively.Inhibition was depending of the time of cultivation and pH values of substrate.
