Decolorization of congo red, rhodamlne B was investigated by the white rot fungus Irpex lacteus welch has biodegrading capability of various recalcitrants. White rot fungus Irpex lacteus is Immobilized by PVA-freezing method. An Immobilized Irpex lacteus decolorizes 91% of congo red In 8 days under culture with glucose 2%(Initial cone.). It also showed 70% of decolorization at 3 days In the state of putting MnSO4 1mM. But, rhodauune B has no significant differences about decolorization among different mixture ratio of Irprx lacteus with PVA, concentration of carbon, nitrogen and manganese sulfate.
