  • Title: Effects of ultrasound on the catalytic activity of matrix-bound glucoamylase.
    Author: Schmidt P, Rosenfeld E, Millner R, Schellenberger A.
    Journal: Ultrasonics; 1987 Sep; 25(5):295-9. PubMed ID: 3116735.
    Abstract:
    The effect of ultrasonic waves on the activity of glucoamylase bound to a porous polystyrene matrix is investigated in this Paper. The immobilized enzyme was sonated in a flow cuvette at frequencies between 1 and 11 MHz and sound intensities up to 5 kW m-2. The effect was measured as a function of the type and concentration of the substrate, carrier particle size, flow rate of the substrate solution and ultrasonic frequency. The activity increase is discussed in terms of a possible ultrasonic mechanism.
