The research was aimed at screening the fungal species from textile effluent that can degrade/decolourize the effluent and modify the fungal isolates for better decolourization process, to acceptable standards, prior to discharge of effluent into receiving water body. Textile effluents were collected from a Textile Company, located at Challawa Industrial Estate, Kano, Nigeria. Physico-chemical parameters such as Temp, pH, Total dissolved solids, Total suspended solid and Heavy metals analyses e.g. Cd, Pb, Mn, Cu and Fe were determined. Eight (8) different fungal species were isolated. Aspergillus niger and Penicillium spp were selected; Aspergillus niger (AN) and Penicillium spp (PN) were modified with ultraviolet rays at 254nm using 20 min. The mutant organisms of Aniger (ANµ2) and Penicillium spp (PNµ2) had higher decolourization potential of 82.81% and 59.64% respectively. Highest potential were observed in consortium of these isolates, when urea fertilizer was added to the effluent, in which maximum decolourization of 98.64% was observed in the consortium of the two fungal isolates with rapid production of biomass of 7.14 mg/ml. The overwhelming pollution of Challawa River with textile effluent can be controlled by employing the combination of two mutant strains of Aspergillus niger and Penicillium spp.


Key words: Decolourization, Effluent, Heavy metals, Aspergillus nigerPenicillium spp.
