LITERATURE

immobilization of Bacillus licheniformis L-arabinose isomerase on aminopropyl glass modified with glutaraldehyde (4 mg protein g per support) enhances the enzyme activity. The immobilized BLAI enzyme achieves 145% of the activity of the free enzyme, and the catalytic efficiency (kcat/Km) is improved 1.47fold after immobilization compared to the free enzyme. Immobilized enzyme on aminopropyl glass has about 30% higher activity than that on Eupergit C and 95% higher activity than that on agarose

immobilization of L-arabinose isomerase with alginate results in less loss of activity, and the entrapped Escherichia coli cell harboring L-arabinose isomerase shows excellent stability

in the presence of 1 mM of the supramolecule NoriaPG, the enzyme preserves more than 90% of its standard activity at 40, 45 and 50°C after incubation for 2 h. Addition of 1 mM of the supramolecules Noria or NoriaPG in the presence of 0.8 mM Mg2+ and 0.8 mM Mn2+ leads to increased stabilization of the enzyme
