dc.description.abstractFungi represent the main route of vanadium’s entrance in ecosystem and are known to tolerate high concentrations of this transition metal. Despite it, its effects on antioxidant systems of fungi are not well-known. The aim of this research was to examine the effects of vanadate on antioxidant enzymes and non-enzymatic antioxidants of filamentous fungus P. blakesleeanus. Mycelium in early exponential (20h) and stationary (56h) phase of growth was treated with relatively high concentrations of V+5 (1, 5 and 10 mM) for 1h or 5h. Activities of peroxidase (POD), glutathione reductase (GR), glutathione transferase (GST), glutathione peroxidase (GPx), concentrations of total phenols and total glutathione were examined. In the 20h old mycelia, V5+ in all concentrations, after 1h treatments, induced decrease in total phenols with the largest decrease (25 ± 4%) after 10mM V5+ treatment, while in 56h old mycelia decrease in total phenols was noticed only after 1 mM V+5 treatment (11 ± 3%). Decrease of total glutathione, in 56h old mycelia, was noticed for all concentrations after 1h treatments, and the largest 38 ± 7% was induced by 5 mM V5+. The same effect was noticed in 20h old mycelia treated for 5h, with the largest decrease of 29 ± 7% after 5 mM V5+ treatment. In 56h old mycelia, after 1h treatments with 10 mM V+5, activities of GPx and POD increased, while after 5h treatments, concentration dependent increase in activities of GST, GPx and GR was noticed, with the largest increase of 112 ± 30% for GPx, 74 ± 39% for GST and 68 ± 26% for GR. Increase in the activities of GPx and GST was noticed in 20h old mycelia treated for 5h, with 5 mM and 10 mM V+5 and also increase of POD in 56h old mycelia, was noticed in same treatments, but the only statistically significant increase was after treatment with 10 mMV+5 in 56h old mycelia (43 ± 10%). The results shown indicate that after 1h treatments, V5+ influenced primarily on non-enzymatic antioxidants and after 5h treatments on enzymes.
