摘要
Three new, water-soluble, N-modified chitosan derivatives containing poly(ethylene glycol), dextran or inulin side chains were used as spacers for enzyme immobilization on a natural silk carrier. Amylolytic enzymes Maltogenase L and Promozyme D2, lipolytic enzyme Resinase HT and a complex of proteolytic enzymes from Streptomyces flavus 197 were immobilized. The activity of the immobilized enzymes and their stability during storage were similar to that obtained with synthetic polyamine-poly(ethylene imine) as a spacer. High operational stability of co-immobilized amylolytic enzymes Maltogenase L and Promozyme D2 in a continuous flow mini-reactor was demonstrated.
