    Abstract: Process for the preparation of a beta -lactam antibiotic in which a beta -lactam nucleus is subjected to an enzymatic acylation reaction with the aid of an acylation agent at a molar ratio of acylation agent/ beta -lactam nucleus of less than 2.5, with the acylation agent and/or the beta -lactam nucleus being supersaturated in the reaction mixture during at least part of the acylation reaction. In the process, a concentrated slurry or solution, for instance, of the beta -lactam nucleus and/or the acylation agent with a different pH or a higher temperature than the pH or temperature at which the acylation reaction is carried out is added to the reaction mixture during the acylation reaction. Both the beta -lactam nucleus and the acylation agent may be supersaturated in the reaction mixture.
