| Abstract | ||
| The potential of Pleurotus eryngii was studied for decolorization ability of different types of textile dyes which were screened on liquid medium. During decolorization study on seven textile dyes, it was found that P. eryngii had the most efficient decolorization on reactive Blue 21 with decolorization percentage (98.4%). On the other hand, the immobilized P. eryngii on wheat straw, rice straw, sugar cane waste and wheat bran had biodegradation ability of Blue 21 dye. The immobilization of fungus on sugar cane waste gave more efficient decolorization of Blue 21 with decolorization percentage (83.5%). Also it was found that the decolorization percentage in case of free P. eryngii was (50.8%). The fungus has the ability to produce lignin-degrading enzymes as laccase, Mn peroxidase, peroxidase and catechol oxidase enzymes. Immobilized P. eryngii on sugar cane waste exhibited the ability to treat industrial textile effluent, 85 to 90% reductions of various nutrients including biological oxygen demand (BOD) and chemical oxygen demand COD were achieved and color removal reached to 96%. So, it was suggested that the immobilized P. eryngii might be applicable to textile effluent system. It was found that the reuse of the treated textile effluent with immobilized P. eryngii on sugar cane waste for irrigation of Basil plant and good result similar to that obtained by tap water. | ||
