Notes:
The immobilization of α-amylase and glucoamylase was investigated by several coupling methods on silica carriers, different types of Silokhroms, and silica gels. The most active immobilized mold and bacterial α-amylases and mold glucoamylase were obtained with titanium salts. These activities were twice the value of that obtained by glutaraldehyde or azo coupling. The half-lives of A. oryzae α-amylase, B. subtilis α-amylase, and A. niger glucoamylase, immobilized to silica carriers at 45°C and under continuous operation at a high concentration of substrate, were 14, 35, and 65 days, respectively.
