ABSTRACT

Screening of 11 species with 26 strains of Basidiomycetes of different ecological niches showed that carboxymethyl cellulase and xylanase levels are low in most investigated species and strains under conditions of submerged fermentation. Trametes hirsutus, 71, Gloeophyllum trabelum, 765, and Trametes versicolor, 145, showed high carboxymethyl cellulase activity (5.65 U/mL, 4.75 U/mL, and 4.29 U/mL), and T. versicolor, 897, was good producer of xylanase (5.54 U/mL). High levels of laccase activity in submerged fermentation of mandarine peels were found in Omphalotus olearius, 174, T. versicolor, 775, and Pleurotus ostreatus, 98 (100.1 nkat/mL, 74.8 nkat/mL, and 62.0 nkat/mL). In solid-state fermentation of mandarine peels, production of laccase was higher, for example in T. versicolor, 145 (104.1 nkat/mL). The highest level of manganese peroxidase activity was in Phellinus robustus, 250 (57.7 nkat/mL). All fungi displayed low levels of all investigated enzyme activity during submerged cultivation in glucosecontaining medium.
