DEVELOPMENT OF A BIOREACTOR SYSTEM USING AN IMMOBILIZED WHITE-ROT FUNGUS FOR DECOLORIZATION .2. CONTINUOUS DECOLORIZATION TESTS

In this paper the fixed film reactor system containing immobilized Pha nerochaete chrysosporium cells was employed for decolorization of Red 533 dispersed dye. The inlet dye concentration and the inlet flow rate were shown to affect the decolorization efficiency. Each decolorizati on process was conducted continuously for 10-20 days or more and the d ecolorization efficiency remained higher than 80%. The immobilized cul tures possessed good biological activities and the biodegrading system also showed capability for a long term operation.
