Abstract :

The white- rot fungus phanerochaete chrysosporium immobilized on the mineral igneous was grown in both stationary and agitated cultures using either carbon- or nitrogen-limited growth medium to study the ability of the fungus to degrade various types of textile dyes. Kiss iris immobilized white-rot fungi phanerochaete chrysosporium could completely decolorize 45 ppm of divers structural dye classes: azoic, reactive, acid, basic, disperse and metal-complex within 7-15 days. Except               metal-complex the only decolorized by biological absorption, other classes of dyes degraded by lignins and manganese peroxides enzymes produced by the fungus.  During the decolorizing process, activity of lignins and manganese peroxides enzymes was observed. Maximum activity of each of them, in the shaken and immobilized culture within 8 & 9 was 174 U/L and 500 U/L, respectively
