Sažetak
In this work the evaluation of use of compounds produced by Trametes versicolor (L.: Fr.) Pilat in control of the aflatoxins biosynthesis by Aspergillus parasiticus is reported. T. versicolor is a medicinal mushroom well-known for the production of some glycoproteins with antitumoral, antiviral, and an ti oxidant properties. Six different isolates of this mushroom were studied for their ability to produce compounds able to control the aflatoxins synthesis. Both lyophilized culture filtrates (LF) and lyophilized mycelial extracts (EM) were tested, and the inhibition of the aflatoxins synthesis from 60% to 90% was observed. There was no significant differences in inhibitory effects between LF and EM of the same strain. The inhibition of toxin production seems to be connected both with the quantity of β-glucans (r2 =0.90 ; p< 0.001) present in LF and EM and with their antioxidant capacity (r2 = 0.88 ; p< 0.01). Further research on the mechanisms of inhibition effectuated by LF and EM has demonstrated that their presence in substrates of cultures induces the activity of some antioxidant enzymes like superoxide dismutase, catalase and glutathion peroxidase. The study has shown the anticipated activation of antioxidant responce of fungal cell and an inhibition of expression of some genes responsible for the synthesis of aflatoxins.
