Abstract: The invention relates to a process for the preparation of an antibiotic, in particular cefalexin, ampicillin, amoxicillin, cefaclor, cefradin, cefadroxil, cefotaxim and the like, wherein a beta-lactam core is acylated, the antibiotic is recovered from the reaction mixture, the remaining mother liquor is subjected to a hydrolysis reaction in which the antibiotic present in the mother liquor is decomposed into its initial compounds, in particular the beta-lactam core, and the acylation agent is hydrolized. The beta-lactam core can then be recovered virtually quantitatively or recycled to the acylation reaction. This is because it has been found that the solubility of the beta-lactam core is unexpectedly high at relatively high concentrations of acylation agent and antibiotic.

Abstract: Penicillin G acylase is immobilized by covalent bonding to a crosslinked mixture of a gelled gelling agent such as gelatin and a polymer containing free amino groups such as alginate amine, chitosan or polyethylene imine. The immobilized penicillin G acylase provides a higher synthesis/hydrolysis ratio as compared to immobilizing with other carriers when producing .beta.-lactam derivatives by a condensing reaction of an amino .beta.-lactam with an acylating agent. The acylating agent may be a derivative of D-phenylglycine, a derivative of D-p-hydroxyphenylglycine or a derivative of D-2,5-dihydro-phenylglycine. Examples of .beta.-lactam derivatives that can be produced are amoxycillin, ampicillin, cephaclor, cephadroxil, cephprozil, cephalexin and cephradine.
