Abstract
Irpex lacteus is a white rot fungus known to decolorize various synthetic dyes. Decolorization of the azo dye Reactive Orange 16 by immobilized culturesof I. lacteus was compared in three different reactor systems of laboratory size: small and large trickle-bed reactors and a rotating-disc reactor. The highest dye decolorization efficiency (90% in 3 days) was observed in the small trickle bed reactor. The production of extracellular ligninolytic enzymes during dye decolorization was measured and the involvement of mycelium-associated activities in the decolorization process assessed. A repeated batch performance test demonstrated the potential of immobilized fungal cultures to decolorize synthetic dyes over long time periods.

Abstract:
Razbarvanje sintetičnega barvila RO 16 z glivo bele trohnobe Irpex lacteus smo proučevali v treh laboratorijskih bioreaktorjih z imobilizirano biomaso: malem in velikem kapalnem reaktorju in reaktorju z rotirajočimi diski. Najbolj učinkovito razbarvanje (90% v treh dneh) je poteklo v malem kapalnem reaktorju kot posledica aktivnosti ekstracelularnih, predvidoma pa tudi na micelij vezanih encimov. Uporaba iste biomase za razbarvanje štirih zaporednih šarž barvila je pokazala na potencialno možnost uporabe imobilizirane kulture v daljšem časovnem obdobju.
