摘要

Six triphenylmethane dyes viz., bromophenol blue, basic fuchsin, methyl violet, methyl green, ethyl violet and malachite green were studied for their decolorization by Fomitopsis feei. Among, basic fuchsin (98%) was maximum decolorized followed by bromophenol blue (96.8%). However, the rate of bromophenol blue decolorization was very fast. There was no correlation between the lignolytic activity and dye decolurization of the dyes. The highest laccase and lignin peroxidase activities were observed in basic fuchsin (46 U/mL) and methyl green (44 U/mL) respectively after 21 days of incubation, which were poor dye degraders. The triphenylmethane reductase enzyme was the responsible enzyme for the decolorization of these triphenyl methane dyes. The treatment by using fungal organisms was considered to be the cost-effective and ecofriendly method of decolourization of effluents discharged from the dye industries.
