Development of an enzyme-immobilized support using a polyester woven fabric

In this study, we aimed to develop an enzyme-immobilized support using polyester woven fabrics and to optimize the development process. We obtained information about the storage stability and reusability of the enzyme and showed the applicability of the polyester woven fabric as an enzyme-immobilized support. In particular, the samples hydrolyzed by hydrogen chloride were treated with N,N’-dicyclohexylcarbodiimide and N-hydroxysuccinimide to activate the surfaces. We evaluated the relative activity of the enzyme immobilization processes, the introduction of spacers, crosslinking and enzyme immobilization and optimized these parameters. The introduction process was controlled to a bovine serum albumin concentration of 1.5% (w/v) and treatment time of 3 h. The crosslinking process was optimized to pH 10.0, a glutaraldehyde concentration of 3% (v/v) and a crosslinking time of 90 min. The immobilization conditions were maintained at pH 8.5, a temperature of 25℃, a time of 45 min and a trypsin concentration of 6% (o.w.f.).
