In order to achieve high activity of enzymatic catalysis,the method of permealizing and crosslinking treatment has been suggested for immobilizing cells with endocelar enzymes.Polyethene polyamine and glutardehyde was used to enhance the activity and stability of E.coli having aspartase entrapped in κ carrageen gel and intact Pseudomonas dacunhae cells having aspartate β decarbonoxylase.The strength and enlargement effects,which favor the performance of catalysis in packed bed reactor and membrane reactor respectively,were also obtained from the experiment results.
