黄孢原毛平革菌对6种染料的脱色降解

在黄孢原毛平革菌与6种染料的液体静培养体系中，不同浓度的染料均发生脱色降解。共培育30 d时，刚果红、直接冻黄G和活性翠蓝KN－G达到92%～99％的脱色率。10，50，100 mg/L活性翠蓝KN－G，50，100 mg/L金莲橙O与天青蓝A，100 mg/L活性艳蓝KN－R的降解率达70%以上；18个样品中60%的降解率超过50%。生物吸附和生物降解是2个重要过程。研究表明，黄孢原毛平革菌对各种染料类群具有广谱有效的脱色降解能力。 

Decolorization and Biodegradation of Six Kinds of Dyes by the White Rot Fungus Phanerochaete chrysosporium

Decolorization and biodegradation occurred in the shallow static liquid culture system of Phanerochaete chrysosporium with 6 kinds of dyes. After incubation of 30 days, the decolorization of Congo Red, Chrysosphenine and Remazol Turquoise Blue G was in range of 92%～99％. The biodegradation efficiency of 10,50,100 mg/L Remazol Turquoise Blue G, 50, 100 mg/L Tropaeolin O and Azure A, and 100 mg/L Remazol Brilliant Blue R is over 70%.60% of 18 samples had the efficiency of biodegradation over 50%. Bioadsorption and biodegradation were both important processes in removal of dyes from the incubation media of Phanerochaete chrysosporium. The investigation showed that this fungus species had broad spectrum and effective ability to decolorize and degrade for vrious groups of dyes.
