Abstract: A process is presented for producing spherical particles containing microorganism cells having desired enzyme activity. The process comprises the steps of mixing the cells directly with a primary or secondary amine-containing polymer, combining the resulting mixture with an organic solvent to form a two-phase system, and then adding a bifunctional cross-linking agent to yield the spherical particles. The preferred enzyme activities are D-amino acid oxidase and glutarylacylase activities.
