This study deals with the decolorization and detoxification of tannery wastewater by an indigenous fungal isolate, Trichoderma viride SPFT1 isolated from untreated tannery wastewater. The results showed that treatment with Trichoderma viride SPFT1 reduced chemical oxygen demand (COD) (74.20%), nitrate (60.83%) and color (45.24%) of the tannery wastewater after six days of the incubation period. The toxicity assessment of the tannery wastewater on Phaseolus mungo L. var. PU-19 showed 70% seed germination in treated wastewater as compared to untreated wastewater (30%). Moreover, untreated tannery wastewater also inhibited seedling growth and reduced chlorophyll content.
