The amino acid and muropeptide compositions of murein (peptidoglycan) isolated from populations of Caulobacter crescentus predominantly composed of swarmer or stalked cells were determined and compared with the structure of murein sacculi obtained fr

Amino acid analysis of pure murein isolated from cells of T. neapolitanus revealed the typical constituents of most mureins form Gram-negative bacteria. i.e. glutamic acid, alanine and diaminopimelic acid, but the molecular ratio ot these was unusual

A number of mutants of Caulobacter crescentus CB15 resistant ot ampicillin were isolated. The mutants differred in their resistance to several beta-lactam antibiotics. No differences in composition of the penicillin-binding proteins of the mutants co

Screening of poorly growing colonies following EMS treatment of Caulobacter crescentus culture revealed several mutants with altered cell morphology. One of these (CB15-UW.5) grew as elongated, helically twisted cells which were more susceptible to a

Amino acid analysis of pure murein isolated from cells of Thiobacillus versutus grown in complex medium revealed the typical constituents of most mureins from gram-negative cells, i.e. muramic acid, glucosamine, glutamic acid, alanine and diaminopime

Partially purified bacterial extracts were prepared from segregated stalked and swarmer bacteria of Caulobacter crescentus and assayed for ATP-dependent deoxyribonuclease activity. This activity was found to be very low in the swarmer bacteria compar

The inactive precursor form of the pneumococcal autolytic enzyme cloned in Escherichia coli was isolated by affinity chromatography on Sepharose-linked choline. The enzyme was recovered in an electrophoretically pure and activated form by elution fro

The action of beta-lactam antibiotics such as ampicillin and benzylpenicillin on cells of Listeria monocytogenes appears to be bacteriostatic. However, after approximately two hours in the presence of 10 x MIC of benzylpenicillin the cells begin to r

Physiological conditions that could provide maximal rates of autolysis of Listeria monocytogenes were examined. L. monocytogenes was found to be refractory to most treatments that promote rapid autolysis in other bacteria. Best rates of autolysis wer
