Low cost CaCl2 pretreatment of sugarcane bagasse for enhancement of textile dyes adsorption and subsequent biodegradation of adsorbed dyes under solid state fermentation

► Dye adsorption capacity of SCB was enhanced by using different pretreatments. ► Among pretreatments studied CaCl2 pretreated SCB shows maximum adsorption capacity. ► Adsorbed dyestuff on CaCl2 pretreated SCB was decolorized under SSF using Providensia stuarti. ► Tray bioreactor was studied for decolorization of adsorbed dyes on CaCl2 treated SCB. ► Analysis of product carried out using FTIR, HPLC and HPTLC confirmed degradation.
