The method is based on the use of Serratia marcescens sensitive to 6-aminopenicillanic acid but comparatively resistant to benzylpenicillin. It is simple, quite specific, and requires no special equipment. It can also be used to screen for phenoxymethylpenicillin acylase activity. We also suggest an acidimetric method for rapid detection of cloned genes in genetic engineering studies of penicillin acylase.Mahidol UniversityBiochemistry, Genetics and Molecular BiologyEnvironmental ScienceImmunology and MicrobiologyArticleSCOPUS
