In this study, Alpha amylase from Bacillus subtilis was immobilized by entrapment in Calcium Alginate beads (CA). To improve the properties of these beads, alginate was blended with Cellulosic Residue (CR) obtained from sorghumstarch extraction. The conditions of entrapment were optimized for a maximum immobilization yield (Y%) by mathematical statistics, where the 23-full factorial design of experiments was used. The properties of calcium alginate beads were improved by comparing the activity of immobilized enzymes in the hydrolysis of starch. The activity of the immobilized enzyme by Calcium Alginate /Cellulosic Residue (CA/CR) was found to be higher than the Calcium Alginate method. Zn2+ and Cu2+ have inhibitory effects on both immobilized enzymes. The Bacillus subtilis immobilized in alginate can be reused for 7 cycles with 12.7 μmol of reduced sugars and 6 cycles for the entrapped enzyme in CA/CR with 30 μmol of reduced sugars.

Water pollution due to release of industrial wastewater has already become a serious problem in almost every industry using dyes to color its products. In this work, polyphenol oxidase enzyme from quince (Cydonia Oblonga) leaves immobilized on calcium alginate beads was used for the successful and effective decolorization of textile industrial effluent. Polyphenol oxidase (PPO) enzyme was extracted from quince (Cydonia Oblonga) leaves and immobilized on calcium alginate beads. The kinetic properties of free and immobilized PPO were determined. Quince leaf PPO enzyme stability was increased after immobilization. The immobilized and free enzymes were employed for the decolorization of textile dyes. The dye solutions were prepared in the concentration of 100 mg/L in distilled water and incubated with free and immobilized quince (Cydonia Oblonga) leaf PPO for one hour. The percent decolorization was calculated by taking untreated dye solution. Immobilized PPO was significantly more effective in decolorizing the dyes as compared to free enzyme. Our results showed that the immobilized quince leaf PPO enzyme could be efficiently used for the removal of synthetic dyes from industrial effluents.
