induction of adenosine deaminase in escherichia coli.supplementing the salts-glucose medium of escherichia coli with adenine initiates induction of adenosine deaminase (adenosine aminohydrolase, ec 3.5.4.4), growth inhibition, and an increased potential for the net deamination of adenine. the extent and duration of these events are proportional to the initial adenine concentration and are dependent upon adenylate pyrophosphorylase and repression of histidine biosynthesis for maximal expression. the conversion of adenine to hypoxanthine, though lim ...19684874315
the influence of bacteriocins on resistance to infection by gram-negative bacteria. ii. colicin action, transfer of colicinogeny, and transfer of antibiotic resistance in urinary infections.dual urinary infections were produced in rats with colicinogenic escherichia coli cf1, elaborating colicin v in the urine, and colicine-sensitive e. coli 9224 by injecting each organism into the medulla of opposite kidneys. the colicin-sensitive organism was eradicated from the urine of 24.3% of rats and the degree of infection by e. coli 9224 reduced to less than half of the control group. colicin-resistant mutants of e. coli 9224 were not inhibited in mixed infections with colicin producing e. ...19684875004
biosynthesis of diacetyl in bacteria and yeast.both diacetyl and acetoin were produced by cell-free extracts and cultures of pseudomonas fluorescens, aerobacter aerogenes, lactobacillus brevis, and saccharomyces cerevisiae 299, whereas only acetoin was produced by cell-free extracts and cultures of streptococcus lactis, serratia marcescens, escherichia coli, and s. cerevisiae strains 513 and 522. cell-free extracts that produced diacetyl did not produce it from acetoin; they produced it from pyruvate, but only if acetyl-coenzyme a was was ad ...19684876127
nonspecific toxicites in the mouse assay test for botulinum toxin.in inoculated pack experiments on clostridium botulinum type e, unirradiated and 0.1-mrad irradiated haddock fillets often gave nonspecific toxicities by the mouse assay test for botulinum toxin. samples given 0.2-mrad radiation failed to produce nonspecific reactions. nonspecific deaths sometimes occurred within 24 hr after injection, although deaths between 24 and 48 hr were more common. the symptoms and the pattern of these deaths suggested a septicemia. heart-blood cultured from mice showing ...19684877496

rapid and sensitive detection of bacteria by gas chromatography.a gas chromatograph fitted with electron capture and flame ionization detectors was employed for the rapid detection of bacteria by analysis for their metabolic products. the presence of proteus vulgaris, streptococcus faecalis, s. liquefaciens, escherichia coli b, bacillus cereus, and b. popilliae was detected in 2 to 4 hr in media inoculated with less than 10(4) cells per ml, whereas a 7- to 12-hr growth period was required for the detection of products formed in cultures of serratia marcescen ...19684967452
effects in hyperoxia upon microorganisms. i. membrane culture technique for exposing cells directly to test atmospheres.a membrane culture technique was developed for directly exposing microorganisms to test atmospheres. inhibition and killing were calculated from comparisons with air-grown cultures. direct colony counts were used with low inocula. with mass inocula, plate colony counts and optical-density measurements were made on resuspended filter populations. bacteria, including escherichia coli, were more sensitive to oxygen than previously reported. with inocula of a few hundred cells per membrane, five of ...19684967757
influence of growth condition on the concentration of potassium in bacillus subtilis var. niger and its possible relationship to cellular ribonucleic acid, teichoic acid and teichuronic acid.1. mg(2+)-limited bacillus subtilis var. niger, growing in a chemostat in a simple salts medium, contained considerably more potassium and phosphorus than mg(2+)-limited aerobacter aerogenes growing in a similar medium at corresponding dilution rates. 2. growth of the bacillus in a k(+)-limited environment did not lower the cellular potassium and phosphorus contents, the molar proportions of cell-bound magnesium, potassium, rna (as nucleotide) and phosphorus being approximately constant at 1:13: ...19684976492
degradation of uric acid by certain aerobic bacteria.we have isolated and identified nine cultures of aerobic bacteria capable of growing on an elective medium containing uric acid as the only source of carbon, nitrogen, and energy. four of these cultures were identified as aerobacter aerogenes, two as klebsiella pneumoniae, and the remainder as serratia killiensis, pseudomonas aeruginosa, and bacillus species. another culture identified as p. fluorescens required both glucose and uric acid for growth. when 23 laboratory stock cultures were inocul ...19684979099

basis for the mutational acquisition of the ability of aerobacter aerogenes to grow on l-mannose.growth of aerobacter aerogenes prl-r3 on the unnatural hexose l-mannose as a sole carbon source is dependent upon the selection of a mutant. growth of the mutant on l-mannose did not require the synthesis of novel enzymes for the degradation of l-mannose, since enzymes of the l-rhamnose degradative pathway could serve this function. however, unlike most other apparent gain mutations that have been described, the mutant was not constitutive for the degradative enzymes; isomerase, kinase, and aldo ...19695354955
control of synthesis of malate dehydrogenase in aerobacter aerogenes.an inverse linear relationship was observed between the levels of l-malate dehydrogenase (mdh) and growth rates of aerobacter aerogenes when grown under aerobic and anaerobic conditions on various substrates which served as the sole carbon and energy sources. deviations from this linearity were found. mdh levels of cells grown aerobically on oxalacetate, l-malate, d-mannose and d-galactose, and of cells grown anaerobically on l-malate and d-mannose were higher than those expected according to th ...19695354938

organization of enzymes in the polyaromatic synthetic pathway: separability in bacteria.ultracentrifugation in sucrose density gradients was employed to estimate the molecular weights and to determine possible physical aggregation of the five enzymes catalyzing steps two to six in the prechorismic acid portion of the polyaromatic synthetic pathway in six species of bacteria: escherichia coli, salmonella typhimurium, aerobacter aerogenes, bacillus subtilis, pseudomonas aeruginosa, and streptomyces coelicolor. the five enzymes were not aggregated in extracts of any of the species exa ...19694979440
enzymatic analysis of the requirement for sodium in aerobic growth of salmonella typhimurium on citrate.na(+) was required for the aerobic growth of salmonella typhimurium on citrate, but not on l-malate, glucose, or glycerol. the maximal growth rate and the maximal total growth occurred with 6 to 7 mm na(+). na(+) could not be replaced by k(+), nh(4) (+), li(+), rb(+), or cs(+). sonically treated extracts of citrate-grown cells contained the enzymes of the citrate fermentation pathway (citritase and oxalacetate decarboxylase) and all of the enzymes of the citric acid cycle. thus, two separate rou ...19694980062
capacity of aspartic acid to increase the bacterial count on suspensions of escherichia coli after freezing.the addition of 2% trypticase to a minimal salts-glucose plating medium increased the bacterial count of frozen and thawed suspensions of escherichia coli 451b cells, even when precautions were taken to remove toxic trace elements from the plating diluent. hydrolysis of the trypticase with hcl or h(2)so(4) reduced its count-increasing activity. treatment of the h(2)so(4) hydrolysate with a cation-exchange resin greatly improved its capacity to replace trypticase. addition of a mixture of amino a ...19694977483
immunochemical and enzymatic comparisons of the tryptophan synthase alpha subunits from five species of enterobacteriaceae.the reactive surface structures of alpha subunits of tryptophan synthase from escherichia coli, shigella dysenteriae, salmonella typhimurium, aerobacter aerogenes, and serratia marcescens were compared by measuring (i) their reactivities in micro-complement-fixation assays with antibodies directed specifically to e. coli wild-type alpha subunit, (ii) their reactivities in enzyme neutralization assays with the same antibodies, and (iii) their binding affinities for tryptophan synthase beta(2) sub ...19694887511

oxidation d-malic and beta-alkylmalic acids wild-type and mutant strains of salmonella typhimurium and by aerobacter aerogenes.a mutant strain of salmonella typhimurium (sl 1634 dml-51) capable of growth on d-malate as sole carbon source was shown to produce d-malic enzyme. this enzyme was absent in the parent wild-type strain which was unable to grow on d-malate. growth of the mutant on d-malate also resulted in a greatly increased level of beta-isopropylmalic enzyme compared with its level in the wild-type strain grown on citrate or l-malate. the d-malic and beta-isopropylmalic enzymes, both of which catalyze a nicoti ...19694889267
polynucleotide sequence relationships among members of enterobacteriaceae.polynucleotide relationships were examined among many representatives of the enterobacteriaceae by means of agar, membrane filter, and hydroxyapatite procedures. the amount of deoxyribonucleic acid (dna) that reassociated was dependent, especially in interspecific reactions, on the annealing temperature. in only three cases: escherichia coli-shigella flexneri, salmonella typhimurium-s. typhi, and proteus mirabilis-p. vulgaris, was relative interspecific duplex formation 80% or higher. in most ca ...19694891264
taxonomic investigations on expressed and cryptic phospho-beta-glucosidases in enterobacteriaceae.in the enterobacteriaceae, beta-glucosides are catabolized by a complex system formed of three permeases, with partly overlapping substrate specificities, and two hydrolytic enzymes, phospho-beta-glucosidase a and b, which hydrolyze only phosphorylated beta-glucosides. some enterobacteriaceae such as klebsiella-aerobacter (enterobacter) possess the complete system; others possess only parts of it or may have a cryptic phospho-beta-glucosidase activity without permease activity. a screening test ...19694897109
structural analysis of colanic acid from escherichia coli by using methylation and base-catalysed fragmentation. comparison with polysaccharides from other bacterial sources.essentially the same methanolysis products were obtained after methylation of the slime and capsular polysaccharides from escherichia coli k12 (s53 and s53c sub-strains) and the slime polysaccharides from e. coli k12 (s61), aerobacter cloacae n.c.t.c. 5290 and salmonella typhimurium sl1543. these were the methyl glycosides of 2-o-methyl-l-fucose, 2,3-di-o-methyl-l-fucose, 2,3-di-o-methyl-d-glucuronic acid methyl ester, 2,4,6-tri-o-methyl-d-glucose, 2,4,6-tri-o-methyl-d-galactose and the pyruvic ...19694902692

effect of growth rate on histidine catabolism and histidase synthesis in aerobacter aerogenes.a study was made of how the catabolism of a carbon and energy source is affected by the biosynthetic demands of growing bacterial cells. cultures of aerobacter aerogenes in l-histidine medium were grown in a chemostat at rates determined by the supply of either sulfate or a required amino acid, l-arginine. it was discovered that the rate at which these cells grow under a biosynthetic restriction determines both the rate and the pattern of histidine degradation. (i) histidine catabolism is partia ...19695781570

requirement for sodium in the anaerobic growth of aerobacter aerogenes on citrate.anaerobic growth of aerobacter aerogenes on citrate as a carbon source required the presence of na(+). the growth rate increased with increasing na(+) concentration and was optimal at 0.10 m na(+). the requirement was specific for na(+), which could not be replaced by k(+), nh(4) (+), li(+), rb(+), or cs(+). k(+) was required for growth in the presence of na(+), the optimal k(+) concentration being 0.15 mm. enzyme profiles were determined on cells grown in three different media: (i) intermediate ...19695784198
induction and properties of the citrate transport system in aerobacter aerogenes.the mediated transport of citrate in aerobacter aerogenes was studied. according to data obtained by examining the distribution of radioactive citrate at room temperature and at 0 c, a carrier system appears to be located on the membrane. the carrier system is inducible and very specific, not acting on the related compounds isocitrate and cis-aconitate. induction required synthesis of both ribonucleic acid and protein as determined by starving auxotrophic mutants and by using specific inhibitors ...19695784212
role of sodium in determining alternate pathways of aerobic citrate catabolism in aerobacter aerogenes.in contrast to the absolute na(+) requirement for anaerobic growth of aerobacter aerogenes on citrate as sole carbon source, aerobic growth of this microorganism did not require the presence of na(+). however, na(+) (optimal concentration, 10 mm) did increase the maximal amount of aerobic growth by 60%, even though it did not change the rate of growth. this increase in growth was specifically affected by na(+), which could not be replaced by k(+), nh(4) (+), li(+), rb(+), or cs(+). enzyme profil ...19695808070

control of respiration and metabolism in growing klebsiella aerogenes. the role of adenine nucleotides.1. a rapid-sampling technique was used to obtain perchloric acid extracts of cells growing in a chemostat culture, so that meaningful values for atp content could be obtained in spite of the fact that the turnover time for the total atp content was about 1sec. 2. for steady-state growth, it was found that, in a glucose-limited chemostat culture, the atp/adp concentration ratio was approximately constant with changes in dissolved-oxygen tensions above the critical value, but fell when the culture ...19694309671
the metabolism of d-glucarate by pseudomonas acidovorans.1. dehydratases that converted d-glucarate into 4-deoxy-5-oxoglucarate were partially purified from klebsiella aerogenes and pseudomonas acidovorans. 2. when d-glucarate was metabolized to 2,5-dioxovalerate it appeared that water and carbon dioxide were removed from 4-deoxy-5-oxoglucarate in one enzymic step: 4,5-dihydroxy-2-oxovalerate was not an intermediate in this reaction. 3. a method for the enzymic determination of d-glucarate is described.19694311826
gram-negative bacilli in burns.in a period of two years, 865 strains of gram-negative bacilli other than pseudomonas aeruginosa isolated from burns were identified by a range of tests. the commonest species were proteus mirabilis, escherichia coli, and enterobacter cloacae. many strains of klebsiella aerogenes, enterobacter aerogenes, and bacterium anitratum were also found.a large proportion of the strains were tested for sensitivity to nalidixic acid, ampicillin, kanamycin, chloramphenicol, tetracycline, and carbenicillin, ...19694312399
