The intrinsic effect of various beta-lactam antibiotics on the biosynthesis of peptidoglycan of Pseudomonas aeruginosa X-48 was investigated. Most of the cephalosporins and penicillins tested already at 0.5 microgram/ml strongly inhibited (a) the incorporation of nascent peptidoglycan into the detergent-insoluble fraction (greater than 75%), (b) the formation of peptide crosslinkages (greater than 60%) and (c) the activity of the DD-carboxypeptidase and partially that of the transpeptidase (approximately 90% and approximately 40% respectively). Another group of beta-lactum drugs did not inhibit incorporation into the material insoluble in sodium dodecylsulfate, the formation of peptide crosslinkages nor transpeptidase activity. They only partially inhibited the activity of the DD-carboxypeptidase--endopeptidase system (40--50% at 0.5 microgram/ml). The results obtained differ from those of Presslitz and Ray [Antimicrob, Agents Chemother. 7, 578--581 (1975)] and show some resemblance to the effects of beta-lactams on the biosynthesis of Escherichia coli peptidoglycan.
