Biodecolourisation of some industrial dyes by white-rot fungi

Eight white-rot fungal strains were screened for biodecolourisation of eight dyes commercially employed in various industries. Decolourisation of Poly R 478 was used as a standard to ascertain the dye-decolourisation potential of various fungi. All the fungi tested significantly decolourised Poly R 478 on solid agar medium. When tested in a nitrogen-limited broth medium, Dichomitus squalens, Irpex flavus Phlebia spp. and Polyporus sanguineus were better industrial dye decolourisers than Phanerochaete chrysosporium.
