Simultaneously immobilized glucose oxidase and catalase in controlled‐pore titania

The immobilization of glucose oxidase and catalase by adsorption within the pores of controlled‐pore titania has yielded a remarkably stable enzyme system. Catalase apparently acts as both a stabilizer and an activator for glucose oxidase within the pores of this material. Hydrogen peroxide concentrations and flow rates have a marked effect upon the apparent activity of the immobilized enzyme system. The carrier parameters were varied to obtain optimum loading and stability information.
