Enzyme Activity of Lipase Immobilized Non-Woven Fabric for Biodiesel Production

This study is to optimize the enzyme(lipase) activity for biodiesel production. The ion-exchanged nonwoven fabrics(EtA, DEA-EtA non-woven fabric) containing ethanolamine, diethylamine groups are used by radiation induced grafted polymerization onto a non-woven fabric for more effective immobilization of lipase. Since the porous hollow fiber membranes are showed the low throughputibehe non-woven fabric membranes are used for biodiesel production. The physical charateristics of enzyme immobilized and the enzyme activity to EtA and DEA-EtA non-woven fabrics are studied. The EtA non-woven fabrics are quite similar to DEA-EtA non-woven fabric for the amount of enzyme immobilized(EtA non-woven fabric: 15.69 mg/g, DEA-EtA non-woven fabric: 14.45 mg/g) but DEA-EtA nonwoven fabrics have shown the lower permeabiliquite the organic solvent than the EtA non-woven fabrics(EtA non-woven fabric: 3.50 mol/h.kg, DEA-EtA non-woven fabric: 0.38 mol/h.kg). Optimum characteristics of ehe non-woven fabric membranes and the limilaractivity are also investigated for the effective biodiesel production.
