9. [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.

Abstract

The content of antibiotics in the discs is the main requirement to their quality. There are 2 methods for determination of the antibiotic content in the discs: (1) a method with preliminary extraction of the antibiotic from the disc followed by determination of its content in the extract biologically and (2) a method using 3 or more standard discs containing different amounts of the antibiotic. A study was performed to show the advantages and limitations of the methods. The conditions for determination of the activity of 22 antibiotics contained in the discs with the method using the standard discs were developed. Comparison of the results obtained with the 2 methods showed that they did not differ significantly. However, it is considered advisable to use for the disc control the method based on direct diffusion of the antibiotic from the disc into agar, since in this case the antibiotic amount in the disc is determined under conditions as much as possible close to the conditions of the disc using for determination of the microbial antibiotic sensitivity.
