title: [Determination of penicillinase and acylase by chromatography on a thin layer of sorbent in the case of their joint formation by different strains].
abstract: The products of penicillinase and acylase hydrolysis of benzylpenicillin were studied with a method of sorbent thin-layer chromatography. The method provided qualitative determination and differentiation of penicillinase and acylase activity in cultures of E. coli capable of simultaneous production of both enzymes. It was shown that when the cultures of E. coli were grown under conditions optimal for acylase production, the amounts of penicillinase were insignificant.
