In the experiment, two spieces of toxigenic Fungi were used: Aspergillus flavus and Aspergillus ochraceus, and the effect of heavy metal salts on potential mycelium biomass growth and spore germination was tested. The salts used were salts of zinc, cadmium, copper, nickel and lead at different concentrations: 5 µg/cm3, 50 (µg/cm3, 100 (µg/cm3, 250 µg/cm3, 500 µg/cm3. The experiments showed that cadmium ions had the most inhibiting effect on both mycelia, whereas zinc appeared to be a growth stimulator. The research on the effects of heavy metals on spore germination enabled us to conclude that despite a good mycelial growth and high biomass in comparison with a control organism, heavy metals significantly restrict the ability to germinate.
