Abstract: Effect of Phanerochaete chrysosporium on decolorization and degradation of dyes in solid media were measured with spectrophotometry.The results show this fungus could degrade azo dye,anthraquinone dye and polymeric dye effectively in solid media such as agar,sand and soil;plant materials like corncob and wood chip could be used as carbon source for co-metabolism of the fungus;the degradating ability of strain BKM-F-1767 was the strongest,the attackability of the fungus on reactive brilliant blue KN-R was better than on Poly R- 478 and Biebrich scarlet.
