Antimicrobial Activities of Basidiocarp, Submerged Mycelium and Exopolysaccharide of Some Native Basidiomycetes Strains

Abstract

In this study, extracts from basidiocarps, submerged grown mycelia and crude exopolysaccharide precipitates of Clavariadelphus
truncatus (Quél.) Donk (Gomphaceae), Coprinus comatus (O.F. Müll.) Pers. (Agaricaceae), Ganoderma carnosum Pat. (Ganodermataceae), Cerrena unicolor (Bull.) Murrill, Laetiporus sulphureus (Bull.) Murrill, Lentinus strigosus (Schwein.) Fr., Lenzites betulina (L.) Fr. and Polyporus arcularius (Batsch) Fr. (Polyporaceae) were tested for antimicrobial activity. The activity
was evaluated by hole-plate diffusion and disk diffusion tests using bacteria and yeasts. Vancomycine and fl uconazole were used
as positive controls for bacteria and yeasts, respectively. The crude exopolysaccharides of Ganoderma carnosum, Polyporus arcularius, Lenzites betulina, Cerrena unicolor; and basidiocarps of Ganoderma carnosum, Laetiporus sulphureus, Coprinus comatus, Lenzites betulina and Clavariadelphus truncatus have relatively high antimicrobial activity. Mycelial extracts from Cerrena unicolor showed the highest antimicrobial activity against the test cultures.
