In this paper, the reaction-diffusion problem in a biocatalyst has been investigated analytically. The efficiency of Differential Transformation Method (DTM) has been demonstrated by solving a problem of chemical/ bio chemical engineering namely, reaction-diffusion process inside a porous biocatalyst in which occurring biochemical reaction follows Michaelis-Menten kinetics. Also the numerical method is used for the validity of this analytical method and excellent agreement is observed between the solutions obtained from DTM and numerical results. Trusting this validity, effects of some other parameters are discussed.
