[Properties of alpha-chymotrypsin enclosed into polycarbonate microcapsules. Estimation of the diffusion effect].

The conditions for the microencapsulation of alpha-chymotrypsin into semi-permeable polycarbonate membranes are selected. The diameter of the microcapsules is 100-150 microns. The microencapsulation can be carried out at any value of pH. The effect of the diffusion in the hydrolysis of some esters by microcapsulated alpha-chymotrypsin was estimated. The thermostability of the microencapsulated enzyme was studied.
