Decolourization Studies Of Synthetic Textile Dye Using Aspergillus Species Under Static And Shaking Conditions

Different fungi have the potentials to decolourize complex and recalcitrant organic compounds into simpler fragments achieving complete mineralization. Optilan red dye and Indosol yellow dye belong to an important group of synthetic dye used in textile industries. They are considered as recalcitrant compound for decolourisation. In this work a batch experiment was conducted for the decolorization of optilan red dye and indosol yellow dye using Aspergillus niger and Aspergillus flavus under static and shaking conditions. At 200mg/L of optilan red dye, 77% and 84 % decolorization was achieved with Aspergillus niger in 8 days interval at static and shaking condition. In case of A. flavus the percentage of decolourization of indosol yellow dye at 200mg/L was found to be 70% and 75%, in 8 days interval at static and shaking condition respectively.This study brings out the ability of Aspergillus species to degrade optilan red dyes and direct yellow dye and reinforces the potential of this group of fungi for the decolorization of textile effluents.
