The stability of an oligomeric enzyme, penicillin acylase, was studied in aqueous media. The enzyme was produced by mutant cells of Escherichia coli ATCC 9637, extracted from the periplasmic space by osmotic shock and further puriยฎed using a pseudo-afยฎnity adsorption process.

The stability of penicillin i n solutions of ephedrine has been determined. At refrigerator temperatures the stability of penicillin is not appreciably affected by ephedrine. At room and incubator temperatures ephedrine exerts an appreciable effect on the stability of penicillin in some preparations
