Recently, treatment of effluents from dye-based industries poses an alarming problem and biotreatment with white-rot fungi could be an alternative.In this study, forty-two submerged cultured white-rot fungal strains were employed for decolorizing Chromazurine, Congo red, Crystal violet, Methylene blue and Neutral red.The most effective strain for dye decolorization of Congo red was Trametes pubescens, with a capacity reaching 98.83% on day 7.Its optimal culture conditions were 2.5 mmol/L-1 copper, 1.0% (V/V) surfactant Tween 80 and 0.50 μmol/L-1 ferulic acid, respectively.The mechanism of decolorization was also monitored by pyroreaction, repeated experiment and UV-visible spectrophotometer.Four metabolites of the dye degradation were identified, namely, naphthalene amine, biphenyl amine, biphenyl, and naphthalene diazonium by FTIR and GC/MS.The non-toxic nature of the metabolites of Congo red was revealed by phytotoxicity tests.Therefore, dye deeolorization by white-rot fungi is a promising strategy to treat textile effluent containing textile dyes.
