From pomiculture waste to biotechnological raw material: efficient transformation using ligninosomes and cellulosomes from Pleurotus spp.

Abstract The goal of this study was to determine the capacity Pleurotus spp. lignocellulosome transform frequent pomiculture residues (grapevine-, plum-, and raspberry sawdust) into raw materials for biotechnological processes. All three lignocellulosics induced synthesis ligninolytic cellulolytic enzymes in tested species. Laccase dominant cocktail, with a maximum activity 40,494.88 U L ?1 observed after cultivation P. pulmonarius on grapevine sawdust. Grapevine sawdust also proved be optimal substrate versatile peroxidases especially eryngii (1010.10 ), while favored production Mn-dependent peroxidase (479.17 ). agent xylanases, endo- exo-cellulases (15,746.35 , 9741.56 836.62 mostly ?-glucosidase (166.11 degree delignification more substrate- than species-dependent, ranging between 6.44 23.72% fermentation . On other hand, lowest level cellulose consumption which together high highest selectivity index (1.27). obtained results show exceptional lignocellulolytic potential enzyme cocktails opens up many possibilities their application numerous Graphical
