The ability of wood rotting fungus, Phanerochaete chrysosporium to decolourise azo dye, Acid Red -18 was investigated. The optimal parameters (pH and cell load) required for effective decolourisation were determined. The strain was capable of decolourising dye over a pH range of 4-6 and decolourisation was rather fast, more than 90% in all cases. The optimal pH 5 and cell load of 2.4 x 10(6) spores/mL is required for complete decolourisation of 100 micromol of azo dye Acid Red-18 at a temperature of 37 degrees C. The fungus proved to be capable of both biodegradation and biosorption, and biosorption was found to be the major dye removal mechanism.
研究了木腐真菌黄孢原毛平革菌对偶氮染料酸性红-18的脱色能力。确定了有效脱色所需的最佳参数（pH值和细胞负载量）。该菌株能够在pH值为4 - 6的范围内使染料脱色，且脱色速度相当快，在所有情况下均超过90%。在37摄氏度下，将100微摩尔的偶氮染料酸性红-18完全脱色，需要最佳pH值为5，细胞负载量为2.4×10(6)个孢子/毫升。结果证明该真菌具有生物降解和生物吸附能力，且发现生物吸附是主要的染料去除机制。
