SYMPOSIUM: Immobilized Enzymes in Food Systems

摘要

ABSTRACTSIntrinsic kinetics of an immobilized enzyme can be different from that of soluble enzyme due to changes of the macromolecule caused by immobilization. Also transport of substrate to enzymic sites on the inert support creates a hindrance to overall reaction. Such diffusional effects on immobilized enzyme reactions were analyzed in terms of effectiveness factor and film factor employing the theories developed earlier in heterogeneous catalysis. The pore diffusion effect in the design of an integral reactor was analytically treated. A brief discussion was given to the diffusional effects in relation to common kinetic studies of immobilized enzymes.
