In this study we focused on the ligninolytic and degradative properties of the edible mushroom Pleurotus ostreatus. Wild strain, the isolates prepared by protoplasting, basidiospore isolation and by crossing of basidiospore-derived isolates were grown under different conditions (liquid culture, solid state fermentation, soil, heavy metal stress conditions) and their ligninolytic (laccase, peroxidases) cellulolytic (endo-1,4-Beta-glucanase, exo-1,4-Beta-glucanase, 1,4-Beta-glucosidase) and hemicellulolytic (endo-1,4-Beta-xylanase, 1,4-Beta-xylosidase and 1,4-Beta-mannosidase) enzyme production was characterized. Selected isolates were tested for the degradation of 14C-labelled lignocellulose and the degradative capacity was determined. The properties of Pleurotus ostreatus isolates in relation to these biotechnological applications are discussed

U divokého kmene P. ostreatus a izolátů připravených protoplastováním, izolací z basidiospor nebo křížením byla sledována produkce ligninolytických, celulolytických a hemicelulolytických enzymů. Vybrané izoláty byly testovány pro degradaci PAH, syntetických barviv a lignocelulosových materiálů
