Abstract

A total of 103 isolates of basidiomycetes, representing 84 species from different Brazilian ecosystems, were evaluated for their antifungal and antibacterial activity in a panel of pathogenic and non-pathogenic microorganisms. Tissue plugs of the fruiting bodies were cultivated in liquid media and the whole culture extracted with ethyl acetate. Crude extracts from Agaricus check for this species in other resources cf. nigrecentulus, Agrocybe perfecta check for this species in other resources , Climacodon pulcherrimus check for this species in other resources , Gloeoporus thelephoroides check for this species in other resources , Hexagonia hydnoides check for this species in other resources , Irpex lacteus check for this species in other resources , Leucoagaricus check for this species in other resources cf. cinereus, Marasmius cf. bellus, Marasmius check for this species in other resources sp., Nothopanus hygrophanus check for this species in other resources , Oudemansiella canarii check for this species in other resources , Pycnoporus sanguineus check for this species in other resources , Phellinus check for this species in other resources sp., and Tyromyces duracinus check for this species in other resources presented significant activity against one or more of the target microorganisms. Eight isolates were active only against bacteria while three inhibited exclusively the growth of fungi. Two extracts presented wide antimicrobial spectrum and were active against both fungi and bacteria. Differences in the bioactivity of extracts obtained from isolates from the same species were observed.
