In situ immobilization of acid protease on mesoporous activated carbon packed column for the production of protein hydrolysates.
The mesoporous activated carbon (MAC) was used as a support material for in situ immobilization of acid protease (AP). The optimum temperature for the activities of both free and immobilized AP was found to be 50 degrees C. The catalytic efficiency of AP-MAC system has significantly been maintained for more than ten consecutive reaction cycles. The functional groups and surface morphology of the AP, MAC and AP-MAC were observed by Fourier transform infrared spectroscopy (FT-IR) and scanning electron microscopy (SEM). The production of protein hydrolysates was carried out from bovine serum albumin (BSA) using AP-MAC packed column and its properties were studied.
