The physicochemical characterization of effluent generated from International Textile Industry (Nig.) LTD Odongunyan Industrial Estate Ikorodu Lagos was carried out. The effluent was analyzed for Biochemical Oxygen Demand (BOD), Dissolved Solid (DS), Colour, Intensity and heavy metals prior to treatment. Pseudomonas aeruginosa and Bacillus subtilis found to have degradative capacity was immobilized on agar-agar, which was transferred into bioreactor fitted with air sparger. The effluent was treated in the bioreactor. The result showed that the effluent was highly polluted using stated parameters. The immobilized cells significantly reduced COD to 200mg/I, BOD to 20mg/l, TS∠ 300mg/I that are upper limit for disposal into surface water. The result indicates overall % reduction in COD, BOD, Nitrate, Sulphate, Phosphates as 83%,97%,61.3%,62.8%,61.2% respectively .Heavy metals were also biosorptioned. It was concluded that immobilized cells represent a promising application in the bioremediation of textile industrial effluent and possible reusability of the cells for its commercial application can be achieved.
