mesosome structure in chromobacterium violaceum.exponentially growing cells of the gram-negative bacterium chromobacterium violaceum demonstrate invaginations of the cytoplasmic membrane with a high frequency. these invaginations conform to the ultrastructural appearance of mesosomes of gram-positive bacteria. as many as four mesosomes are observed per cell, each of which may increase the total membrane surface of the cell by 30%. washing of cells in dilute tris(hydroxymethyl)aminomethane buffer effects a distension of the mesosome "neck" and ...19744828310

properties of an r factor from pseudomonas r factor from pseudomonas aeruginosa, which confers resistance to penicillins, kanamycin, and tetracycline, was studied in escherichia coli k-12. the r factor could coexist with f-like or i-like plasmids and therefore constituted a novel compatibility group. the r factor was transferable from e. coli to bacterial genera outside the enterobacteriaceae (pseudomonas and members of the rhizobiaceae) to which transfer of f-like and i-like plasmids could not be demonstrated.19714945193

effect of cold temperatures on the viability of chromobacterium violaceum.the effect of low, nonfreezing temperatures on the viability of five strains of chromobacterium violaceum was studied. the viability of cultures grown at 30 c was determined after exposure to various diluents held at 0 to 2 c. a culture diluted at its growth temperature served as the control. cells of strain n were most sensitive in the early part of the exponential phase of growth. cells of strains 252 and 341 were most sensitive in the late exponential, early stationary phase of growth. cells ...19695774755
effect of enzymes on the composition and structure of chromobacterium violaceum cell envelopes.cell envelopes of chromobacterium violaceum were isolated and treated under controlled conditions with trypsin, pronase, lipase, phospholipase c, lysozyme, and a mixture of enzymes produced by a bacteriolytic pseudomonas sp. after each enzyme treatment, losses in dry weight, protein, lipid, carbohydrate, 2,6-diaminopimelic acid, and total phosphorus were determined. electron-microscopic examination of the enzyme-treated envelopes indicated complete or partial loss of envelope rigidity or some en ...19695776532

tryptophan synthetic pathway and its regulation in chromobacterium violaceum.extracts of chromobacterium violaceum catalyzed all of the reactions involved in synthesizing tryptophan from chorismic acid. tryptophan auxotrophs which had lost any of these activities did not produce the characteristic purple pigment, violacein, when grown on a medium in which tryptophan was limiting. gel filtration of extracts allowed us to estimate molecular weights for the tryptophan enzymes. all of the enzymes appeared to have molecular weights below 100,000. no enzymes were observed to o ...19685669904
proteus and coliform meningoencephalitis in neonates.the characteristic necropsy and histological appearances are described of nine cases of proteus meningoencephalitis in neonates. one case which was not due to proteus has been included because of the close similarity of the gross appearances of the brain. umbilical sepsis in half the cases indicated that this is a common portal of entry of these organisms. that epidemiological factors may be of importance in the aetiology was suggested by the distribution of cases.19685697343
