Abstract

A mathematical model was developed to estimate the lipase activities from the experimentally obtained physical dimension of halo, formed bya diffusing lipase through agar media. A diffusion equation based upon the mass balance was derived in cylindrical coordinates, the integration of which was carried out by using finite difference method. A regressional analysis of the experimental data using the proposed model has brought the values for the hindered diffusivity of lipase through agar media and the minimum effective Lipase concentration of 0.817 x 10(-6) cm(2)/s and 2.86 unit/cm(3), respectively. The procedures, delineated in this work are considered to be useful for the quantitative analysis of halo-forming enzymes at predetermined standard conditions.
