A theoretical analysis of concentration of lactose hydrolysis in a packed bed reactor using immobilized beta-galactosidase was discussed. The model is based on system of reaction diffusion equations containing a non-linear term related to Michalies-Menten kinetics of enzymatic reaction. In this paper, we obtained approximate analytical expressions for the concentrations of lactose and galactose for an isothermal reaction occurring under diffusive conditions in a packed bed tubular reactor containing immobilized enzyme using a new approach of homotopy perturbation method. The obtained analytical results were found to be in good agreement with the simulation results. (C) 2016 Ain Shams University.
