Abstract

The little studied white rot fungus Ischnoderma resinosum was tested for its ability to decolorize seven different synthetic dyes The strain efficiently decolorized Orange G Amaranth Remazol Brilliant Blue R Cuphthalocyanin and Poly R478 on agar plates and in liquid culture at a relatively high concentration of 2–4 and 05–1 g l−1 respectively Malachite Green and Crystal Violet were decolorized to a lower extent up to the concentration of 01 g l−1 Decolorization capacity of I resinosum was higher than that in Phanerochaete chrysosporium Pleurotus ostreatus or Trametes versicolor In contrast with these thoroughly examined fungi I resinosum was able to degrade a wide spectrum of chemically and structurally different synthetic dyes I resinosum also efficiently decolorized dye mixtures In liquid culture Orange G and Remazol Brilliant Blue R were decolorized most rapidly the process was not affected by different nitrogen content in the media Shaken cultivation strongly inhibited the decolorization of Orange G
