文摘

Halloysite nanotubes are used post surface functionalization for the immobilization of α-amylase. The immobilized enzyme was characterized using TEM, XRD, FTIR and DSC. 69.23% of enzyme was immobilized. Optimum pH and temperature for maximum enzymatic activity was detected to be 7 and 40 °C. Enzymatic activity of immobilized enzyme increased as compared to free enzyme in the presence of Cu2 + and Mn2 + ions.
