Ligninolytická kapacita vybraných hub bílé hniloby kultivovaných v imobilizované formě
Šušla, Martin ; Svobodová, Kateřina ; Tavčar, M. ; Pavko, A. ; Novotný, Čeněk
The work is focused on the ligninolytic capacity of two white-rot fungi, Irpex lacteus and Dichomitus squalens, cultivated in their immobilized form. We measured the production of ligninolytic enzymes (Mn-dependent peroxidase, lignin peroxidase, laccase) by the two fungi immobilized on polyurethane foam or pine wood in a fixed bed laboratory-scale bioreactor. The results were compared to the activity profiles of static liquid cultures of the fungi. Decolorization of an azo dye Reactive Orange 16 by the immobilized cultures of I. lacteus in three different bioreactor systems was also studied as well as the production of ligninolytic enzymes during the decolorization process. The highest dye decolorization efficiency (70% in 2 days) was observed in a small size trickle bed reactors
