Table 1 Growth inhibition (GI) of the selected fungi in the presence of Na₂SeO₃ and Na₂TeO₃. Growth inhibition (GI) was derived from the diameters of fungal colonies, GI = D(control) − D(Na₂SeO₃/Na₂TeO₃)/D(control) − D(original) × 100%; D represents the fungal colony diameter; D(control) represents the expansion diameter of fungal colonies without any addition; D(Na₂SeO₃ / Na₂TeO₃) represents the expansion diameter of fungal colonies with the addition of Na₂SeO₃ or Na₂TeO₃; D(original) represents the original diameter of fungal colonies. For this assay, 200 μL 20 mM sodium selenite (Na₂SeO₃) or sodium tellurite (Na₂TeO₃) were added to each of four 6-mm-diameter wells located equidistant between the growing colony and the edge of the Petri dish. All test fungi were grown on MEA plates with or without Na₂SeO₃ and Na₂TeO₃ for 5 days at 25 °C in the dark. All colony diameters used in the calculations were the means of two measurements for at least three replicates
