Synthetic dyes are released into the environment from textile industrial effluents. It decreases photosynthetic activity and increases toxicity to the living beings. In present paper pollution level was monitored in terms of Biological oxygen demand (BOD) and Chemical oxygen demand (COD). The strain Aspergillus terreus was evaluated for its efficiency to decolorize and decrease BOD and COD values of the effluent. Various inexpensive matrices were used for immobilization of A. terreus viz. Bagasse, coconut coir, Loofa sponge and Gunny bag (Jute). A. terreus immobilized on Bagasse showed 62%, on coconut coir 58.6%, on Loofa sponge 71.7% and on Gunny bag (Jute) 82.66% reduction in BOD. In case of COD reduction, A. terreus immobilized on Bagasse showed 60.25%, on coconut coir 56.31%, on Loofa sponge 69.71% and on Gunny bag (Jute) 81.25%. Amongst all Gunny bag (Jute) was found most efficient immobilizing material for A. terreus to decrease the pollution level and remediation of the effluent.
