The present paper focuses on the use of fungus, Pleurotus ostreatus, to decolorize and degrade azo dye, Synazol Red. Decolorization study showed that P. ostreatus was able to decolorize 96% Synazol Red in 24 days. It was also found that 94% Synazol Red containing dye effluent was decolorized by P. ostreatus after 30 days of incubation at room temperature. The enzyme exhibited highest activity at 70°C and at pH 6.0. The absence of zone of inhibition on agar plates indicated that the fungal degraded dye metabolites are nontoxic to beneficial micro-flora. Therefore, P. ostreatus has promising potential in colour removal from textile wastewater containing azo dyes. |
