Enzyme Immobilization in Collagen Films Adhered to Semi-Rigid Supports: The Enzymatic Sponge Reactor

  • O. Maldonado

Among the newer methods of enzyme and whole cells immobilization which have been successfully developed (1–3) one of the most promising is immobilization in a collagen matrix (4). Three different techniques using collagen matrices have been tried: impregnation, molecular complexation and electrocodeposition. Collagen, one of the most common protein constituents of animal tissues and a major protein component of skin, bone, tendons and other connective tissues is important for its fibrous nature (5–8).
