By Enzyme Immobilization onto Textiles

Christophe Innocent, Patrick Seta

Abstract. Advanced biotechnological techniques are now being used in the chemical engineering of membrane processes, notably enzyme immobilization procedures, biosensors, and, more recently, proteomics. The knowledge and increasingly fine control of the production and reactivity of enzymes also profits research whose aim is to use on a large scale the catalytic material properties of biocatalysts (enzymes). These materials with reactive properties could be introduced into membrane technology, opening as a new field the treatment of liquid media according to the concept of membrane bioreactors, where the membrane itself acts as the chemical reactor. As will be discussed herein, the ionic-exchanging textiles will be involved in this futurology.

The concept of the chemical microreactor is becoming increasingly important not only because the industrial community must now protect the environment, but also in the developments in biotechnology and in the field of health. With regard to the increasing need to protect the environment, for example, there is a need for the development of waste treatment processes that are more effective and are easily combined or coupled with other processes, or still better able to fulfill several functions in only one operation (unitary process). Membrane technology, and in particular the processes involved in separation already utilize this concept of unitary operation, and the concept of catalytic membranes has experienced significant developments as regards, for example, gas treatment (Dalmon 1997). The chemical reactivity of liquid media has also been tested with membrane bioreactors, where the membrane is not the site of chemical or biochemical reactions of transformation. In such bioreactors the membrane is just a separator
