IMMOBILIZED MICROBIAL CELLS AND PROCESSES FOR PREPARING AND USING THE SAME ABSTRACT A composition comprising immobilized cells having enzyme activity, the cells being immobilized by means of a fixed, insoluble, crosslinked polymer obtained by curing a curable prepolymer material selected from the group consisting of polyazetidine prepolymers, carboxymethyl cellulose, polyurethane hydrogel prepolymers and polymethylene isocyanates, said polymer being cured at a temperature below the temperature at which the enzyme activity of the microbial cells is significantly reduced, the cell/crosslinked polymer composition constituting a coating on a solid inert carrier. The composi- tion may be used in various ways, for example, to prepare L-aspartic acid.
