[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 ...	1976	933867
microbiological degradation of bile acids. the conjugation of a certain cholic acid metabolite with amino acids in corynebacterium equi.	1. (4r)-4[4alpha-(2-carboxyethyl)-3aalpha-hexahydro-7abeta-methyl-5-oxoindan-1beta-yl]valeric acid (ii) could not be utilized by arthrobacter simplex, even though the acid was one of the metabolites formed from cholic acid (i) by this organism. therefore the further degradation of the acid (ii) by corynebacterium equi was investigated to identify the intermediates involved in the cholic acid degradation. 2. the organism, cultured in a medium containing the acid (ii) as the sole source of carbon, ...	1976	1016254
identification of the cultivable bacteria in dental plaque from the beagle dog.	fifteen different genera of microorganisms were isolated from the 27-month-old plaque of two beagle dogs. they were as follows: pseudomonas, proteus, neisseria, escherichia, staphylococcus, streptococcus, lactobacillus, nocardia, actinomyces, corynebacterium, micrococcus, microbacterium, brevibacterium, arthrobacter, and kurthia. the dog plaque was characterized by a low number of streptococci and the presence of several noncarbohydrate-fermenting organisms.	1976	1069758
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 ...	1976	825611
[survival of epiphytic microorganisms following sublimation dehydration and storage].	epiphytic microorganisms belonging to the genera pseudomonas, agrobacterium, achromobacter, flavobacterium, mycobacterium, mycococcus, nocardia, corynebacterium, arthrobacter, bacillus, and microbacterium were dehydrated by sublimation employing two suspension media, and were stored at 3-5 degrees c during 1-2.5 years. survival of epiphytic microorganisms upon dehydration by sublimation and storage was found to depend on their taxonomy (genus, species, strain) and the composition of the suspensi ...	1976	1004279
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 ...	1976	829205
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.	1976	943220
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 ...	1976	956128
ring hydroxylation of p-chlorophenylacetate by an arthrobacter strain.	resting cell suspensions of a strain of arthrobacter grown on phenylacetate converted p-chlorophenylacetate to two products. one of the products was identified as 4-chloro-3-hydroxyphenylacetate.	1976	970937
restriction-enzyme-cleavage maps of bacteriophage m13. existence of an intergenic region on the m13 genome.	replicative form dna of bacteriophage m13 was cleaved into specific fragments by an endonuclease isolated from hemophilus aegyptius (endor.haeii) and an endonuclease from arthrobacter luteus (endor.alui). the fragments were ordered as to construct a circular map of the phage m13 genome by: (a) using each fragment as a primer for the synthesis in vitro of its respective neighbour and (b) digesting the isolated fragments with the hemophilus aegyptius enzyme endor.haeii or the hemophilus aphirophil ...	1976	786638
[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 ...	1976	979679
