Alpha-amylase was immobilized onto polyaniline-polyvinyl alcohol (PAni-PVA) film by cross linking with glutaraldehyde. The activity yield and immobilization efficiency was calculated as 13.58% and 30.60% respectively. The PAni-PVA-Amylase films were characterized by Fourier Transform Infrared Spectroscopy (FTIR) and amylase activity assay. The immobilized a-amylase had its optimum activity at pH 7.0 and 25 degrees C. The immobilization of alpha-amylase onto the PAni-PVA films protected the enzyme from Fe2+ inhibition. The PAni-PVA-Amylase films could be used effectively for 30 cycles with 60% retention of the activity. (C) 2013 Elsevier B.V. All rights reserved.
