Description	The study focuses on the production of ligninolytic enzymes and dye degradation capacity of Dichomitus squalens immobilized on polyurethane foam (PUF) or pine wood (PW) in a fixed bed reactor at a laboratory-scale (working volume of 0.6 l). Immobilization of fungal cultures on pine wood improved eminently laccase production in comparision to the liquid cultures. Immobilized D. squalens was able to decolorize an anthraquinone dye Remazol Brilliant Blue R and an azo dye Reactive Orange 16, however, only a limited decolorization of Copper(II)phthalocyanine dye was observed in both types of reactor cultures.

Imobilizace na dřevě výrazně zvýšila produkci laccasy ve srovnáním s tekutými kulturami. Imobilizovaná houba byla schopna dekolorizace RBBR a RO16, avšak pouze omezeně odbarvovala Cu(II)ftalocyanin. Výsledky svědčí pro roli laccasy v biodegradaci barviv. Byly izolovány dva izoenzymy laccasy pomocí FPLC, oba o MW 68 kDa a stejné hodnotě pI. Oba izoenzymy se lišily v katalytických vlastnostech jako jsou závislost na pH a rachlost oxidace ABTS. Byly demonstrovány různé schopnosti obou izoenzymů dekolorizovat různá barviva (cs)
