Abstract: Based on the systematical study of continuous resolution of DL-alanine employing the immobilized Aspergillus oryzae cell, the kinetics of the enzymic reaction was determined. Furthermore, the method of Newton-Raphson was applied to the solution of one-dimension-steady-diffusion model of packed bed for continuous resolution of DL-alanine. The calculated results of the model, with the error less than 10%, were in good agreement with those of experiments. It was demonstrated that the model was reasonable and accurate.

Key words: : immobilization, Aspergillus oryzae cell, DL-alanine, resolution, packed-bed, kinetics
