induction of d-6-hydroxynicotine oxidase in resting cells of arthrobacter oxidans.resting cell suspensions of arthrobacter oxidans were shown to synthesize the inducible enantiozyme, d-6-hydroxynicotine oxidase, in the presence of d-nicotine or d-6-hydroxynicotine. the corresponding l-enantiomers, as well as gamma-methylaminopropyl-(6-oh-pyridyl-3)-ketone, which is the product of the reaction catalyzed by the enzyme, were ineffective as inducers. l-6-hydroxynicotine inhibited induction by d-nicotine and d-6-hydroxynicotine while l-nicotine inhibited induction by d-6-hydroxyni ...19761015955
macromolecular synthesis and cell division during morphogenesis of arthrobacter crystallopoietes.the sphere-rod-sphere morphology cycle of arthrobacter crystallopoietes was accompanied by changes in the rate of growth and the rates of dna, rna and protein synthesis. the patterns of macromolecule synthesis resembled those found in other bacteria during a step-up followed by a step-down in growth rate. during the step-up in growth spherical cells grew into rods and macromolecules were synthesized in the absence of cell division. during step-down, successive rounds of septation produced progre ...19761015960
[mode of action of d-amino acids on the biosynthesis of peptidoglycan (author's transl)].the mechanism of growth inhibition by d-amino acids was studied. d-serine at concentrations from 0.02-0.2 m was sufficient to cause partial growth inhibition in seven species of bacteria representing the four most common types of peptidoglycan. the inhibited cells displayed morphological alterations. in the nucleotide-activated peptidoglycan precursors of these cells, d-alanine residues in position 4 and/or 5 of the peptide moiety were partially or even completely replaced by d-serine. the pepti ...1976825075

microbiological characteristics of natural mineral water.natural, non-carbonated mineral water is, like every other natural water from a spring, never sterile. however, the microbial level is always very low. but after its bottling, the level rises rapidly and numbers of more than 10,000 to 100,000/ml can be reached. in principle 2 groups of bacteria of very different origin and properties can be found in the microbial flora of the bottled, non-carbonated mineral water. allochthonous bacteria will get into the water by contamination from the container ...1976829205
growth and pigment production by arthrobacter pyridinolis n. sp.a new bacterium capable of growing on 2-hydroxypyridine as sole source of carbon and nitrogen was isolated from soil. during its growth on solid medium, approximately 50% of this substrate was converted to a brilliant blue crystalline pigment which was deposited extracellularly in the colony mass. the pigment was identical to that produced by arthrobacter crystallopoietes during its growth on 2-hydroxypyridine. the new isolate exhibited the typical cycle of morphogenesis characteristic of the ge ...19761015948
natural paucity of anaplerotic enzymes: basis for dependence of arthrobacter pyridinolis on l-malate for growth.previous work has shown that in arthrobacter pyridinolis the transport systems for glucose and several amino acids are respiration coupled, with malate oxidation occurring concomitantly with transport. the requisite malate has to be supplied exogenously, so that growth on glucose or certain amino acids only occurs if malate is also present in the medium. these and other data suggested that a. pyridinolis might be deficient in anaplerotic enzymes, which maintain intracellular levels of dicarboxyl ...1976931946
[oxidation and assimilation pathways of methylated amines in arthrobacter globiformis].the oxidation by arthrobacter globiformis b-175 of tertiary, secondary, and primary amines is catalyzed by specific induced enzymes. trimethylamine is oxidized to dimethylamine via trimethylamine n-oxide by monooxygenase and demethylase. dimethylamine is converted to methylamine by another monooxygenase. methylamine is oxidized to ammonia and formaldehyde by aminoxidase. formaldehyde is assimilated via ribulose monophosphate cycle, which is confirmed by the presence of hexose-phosphate synthase ...1976933867
soybean flower-to-seed movement of epiphytic bacteria.epiphytic tracer bacteris (a pseudomonas sp. and an arthrobacter sp.) from soybean buds were introduced into open flowers of greenhouse-grown soybean plants. of the 177 resulting pods cultured after surface disinfection, tracers were recovered from within 24. seed from two of these pods also carried tracers.1976943220

motility as a morphogenic character in the genus arthrobacter.motility in arthrobacter atrocyaneus, a. citreus, and a. simplex was found to correlate with the morphogenic cycle of these organisms. the percentage of the a. atrocyaneus and a. simplex populations that were flagellated at a given time during the growth cycle differed significantly from that of the normorphogenic pseudomonas aeruginosa population. flagellation in a. atrocyaneus was shown to be dependent upon the morphogenic cycle rather than upon growth. the commitment to flagellar synthesis in ...1976956128
thin-layer chromatographic analysis of mycolic acid and other long-chain components in whole-organism methanolysates of coryneform and related taxa.acid methanolysates of strains representing 58 coryneform taxa were examined for mycolic acids and other long-chain constituents by thin-layer chromatography. mycolic esters were detected in the methanolysates of true corynebacteria but not in those from plant pathogenic bacteria, corynebacterium haemolyticum, corynebacterium pyogenes or from representatives of the genera arthrobacter, cellulomonas, curtobacterium, kurthia or oerskovia. thin-layer chromatography of whole-organism methanolysates ...1976825611
[effect of nitrogen source on growth of arthrobacter simplex and its biosynthesis of cholinesterase].the effect of organic and inorganic forms of nitrogen on biomass accumulation and cholinesterase synthesis was studied with arthrobacter simplex var. cholinesterasus. the culture assimilates nitrogen of ammonium compounds better than other forms of inorganic nitrogen; the best nitrogen source for biosynthesis of cholinesterase is ammonium phosphate. nitrogen of nitrates is not assimilated. the amount of biomass is almost twice as high on the medium with peptone, casein or casein hydrolysate as o ...1976979679
