ABSTRACT:
Microbial cells are immobilized with a curable polyaziridine or polyfunctional aziridine prepolymer to obtain an insoluble, crosslinked polymer containing the cells. The microbial cells immobilized may be cells having L-aspartase or L-phenylalanine transaminase activity for the production of L-aspartic acid or L-phenylalanine. The polymer containing the cells may be formed as a coating on a solid inert carrier.
