The Influence of Ultrasound on Matrix-Bound Enzymes

  • P. Schmidt

Immobilized enzymes are enzymes which have been linked to insoluble carriers either by chemical or physical attachement or by some form of entrapment. As heterogeneous catalysts they differ in many respects from their soluble counterparts and they are of theoretical and practical interest for many reasons. With the application of ultrasound two aims are purposed:
  1. (i)

    The alteration of the carrier structure by the action of high power ultrasound, which is of technological importance, and

  2. (ii)

    the study of ultrasonic effects on the enzymatic reaction itself.
