Mycelia of Trametes versicolor, Coniophora puteana and Poria monticola were grown on potato dextrose agar (PDA) media, containing various concentrations of copper N,N-dimethyldithiocarbamoylacetate (which may be regarded as a copper S-substituted thioglycolate). The tested copper compound revealed relatively low fungicidal activity. After 13-18 day growing period, we determined concentrations of absorbed copper in the isolated mycelia by flame atomic absorption spectroscopy. Contents of copper in mycelia were the highest at the highest two concentrations of S-substituted thioglycolate and reached the value of 150 µg/g of mycelium of Trametes versicolor and 370 µg/g in the case of Coniophora puteana. On the other hand, uptake of copper by Poria monticola was lower - only up to 40 µg/g.
