| [sulfur and iron cycling bacteria in low-sulfate meromictic lake kuznechikha]. | the hydrochemical characteristics, the composition of species and the localization of bacterial species involved in oxidation of sulfide and ferrous salts were studied in the meromictic lake kuznechikha with a low sulfate content in summer and in winter. the rate of bacterial sulfate reduction and the rates of bacterial and algal photosynthesis were determined using a radioisotope technique. the meromictic nature of the lake is due to the accumulation of ferrous salts (up to 212 mg/l fe2+) in th ... | 1980 | 6777648 |
| effect of oxygen on batch and continuous cultures of a nitrogen-fixing arthrobacter sp. | growth, acetylene reduction, and respiration rate were studied in batch and continuous cultures of arthrobacter fluorescents at different oxygen partial pressures. the optimum po2 values for growth and acetylene reduction were 0.05 and 0.025 atm, respectively, but microorganisms can tolerate higher po2 values. the growth of cultures provided with combined nitrogen was dependent on oxygen availability, and strict anaerobic conditions did not support growth. acetylene reduction of a population gro ... | 1979 | 476551 |
| emulsifier of arthrobacter rag-1: isolation and emulsifying properties. | the oil-degrading arthrobacter sp. rag-1 produced an extracellular nondialyzable emulsifying agent when grown on hexadecane, ethanol, or acetate medium. the emulsifier was prepared by two procedures: (i) heptane extraction of the cell-free culture medium and (ii) precipitation with ammonium sulfate. a convenient assay was developed for measurement of emulsifier concentrations between 3 and 75 micrograms/ml. the rate of emulsion fromation was proportional to both hydrocarbon and emulsifier concen ... | 1979 | 36840 |
| effect of starvation on survival of three bacterial isolates from an arctic soil. | three isolates, a pseudomonas sp., a bacillus sp. and an arthrobacter sp., which had been isolated from a meadow soil at devon island, canada, were subjected to starvation under varying conditions. the viabilities of the three isolates during starvation for 30 days in a carbon-free medium was assessed after the organisms had been grown continuously at varying rates in carbon- and nitrogen-limited media at 5 and 15 degrees c. pseudomonas m216 was the most resistant to starvation stress, bacillus ... | 1978 | 747809 |
| effect of freezing and thawing on survival of three bacterial isolates from an arctic soil. | three isolates, a pseudomonas sp., bacillus sp., and arthrobacter sp., which had been isolated from a meadow soil at devon island, canada, were subjected to freezing and thawing at low rates under various conditions. when cells were frozen in sand or soil, survival was dependent on moisture level, storage time, and thaw rate. pseudomonas m216 was most susceptible to freeze-thaw damage under these conditions. arthrobacter m51 was the most resistant of the three isolates when frozen in sand or soi ... | 1978 | 747810 |
| growth characteristics of three bacterial isolates from an arctic soil. | three bacterial isolates, a pseudomonas sp., a bacillus sp., and an arthrobacter sp., commonly isolated from a hummocky sedge-moss meadow at devon island, n.w.t., canada, were selected for further taxonomic characterization and for a study of the effects of temperature and limiting carbon source on growth. pseudomonas m216 resembled p. putida and bacillus m153, b. carotarum. arthrobacter m51 had growth-factor requirements which were more complex than those of any named species of that genus. the ... | 1978 | 688099 |
| metabolism of di- and mono-n-butyl phthalate by soil bacteria. | di-n-butyl phthalate and other dialkyl phthalates are used as carbon sources by three nocardia sp. isolates; mono-n-butyl phthalate is used as a carbon source by an arthrobacter sp. isolate and a pseudomonas sp. isolate. the compounds were metabolized in these organisms by hydrolysis to the corresponding monoesters and free phthalic acid. phthalic acid was then metabolized via protocatechuic acid by 3,4-dioxygenative ring cleavage. | 1978 | 16345266 |
| the catabolism of l-tyrosine by an arthrobacter sp. | an arthrobacter sp. metabolizes l-tyrosine by a pathway involving 3,4-dihydroxyphenylacetate as a key intermediate. p-hydroxyphenylpyruvate is formed from tyrosine by an amino-transferase specifically requiring alpha-ketoglutarate for activity, and is then converted to p-hydroxyphenylacetate by an oxidative decarboxylation. p-hydroxyphenylacetaldehyde is not an intermediate in the formation of p-hydroxyphenylacetate. extracts of the bacterium oxidize 3,4-dihydroxyphenylacetate to delta-carboxyme ... | 1977 | 20216 |
| nitrification in histosols: a potential role for the heterotrophic nitrifier. | insufficient populations of nitrosomonas and nitrobacter were found in a pahokee muck soil (lithic medidaprit) to account for the nitrate concentration observed. to determine if heterotrophic nitrifiers could account for some of this discrepancy, a method was developed to measure the levels of heterotrophic nitrifiers in soil. a population of 4.1 x 10(5) arthrobacter per g of dry fallow soil, capable of producing nitrite and/or nitrate from reduced nitrogenous compounds, was observed. amendment ... | 1977 | 869537 |
| structural and immunochemical studies on d-arabino-d-mannans and d-mannans of mycobacterium tuberculosis and other mycobacterium species. | serologically active d-arabino-d-mannas ([alpha]d, +82 degrees approximately 89 degrees; ratio of d-arabinose to d-mannose, 1-2:1) were isolated from the soluble fraction of disintegrated cells of m. tuberculosis, m. smegmatis, and several other mycobacterium species. these arabinomannans had similar structures, consisting of alpha-(1 leads to 5)-linked d-arabinose residues and alpha-(1 leads to 6)-, and (1 leads to 2)-linked d-mannose residues. methylation and enzymic degradation studies using ... | 1977 | 413830 |
| new microbial growth factor. | a screening procedure was used to isolate from soil a penicillium sp., two bacterial isolates, and a streptomyces sp. that produced a new microbial growth factor. this factor was an absolute growth requirement for three soil bacteria. the penicillium sp. and one of the bacteria requiring the factor, an arthrobacter sp., were selected for more extensive study concerning the production and characteristics of the growth factor. it did not seem to be related to the siderochromes. it was not present ... | 1977 | 327929 |
| oxidation of linear terpenes and squalene variants by arthrobacter sp. | cells of arthrobacter sp. that had been isolated from soil were used to study oxidation of some linear terpenes and squalene variants. the cells oxidized geraniol, nerol, and farnesol to the corresponding aldehydes, with partial conversion of the geometrical isomerism of the alpha,beta-double bond. the squalene variant, squalene-2,3-oxide, was cleaved to 9,10-epoxygeranylacetone and geranylacetone. squalene-2,3-22,23-dioxide was cleaved to 9,10-epoxygeranylacetone. these products were optically ... | 1977 | 869527 |
| facultative wood-digesting bacteria from the hind-gut of the termite reticulitermes hesperus. | among the facultative bacteria capable of growth on mesquite wood which were isolated from the asceptically dissected hind-gut of the termite reticulitermes hesperus were two strains of bacillus cereus, one strain each of arthrobacter, alcaligenes and serratia, and a very small gram-negative fermentative rod. the b. cereus strains, the serratia marcescens strain and the arthrobacter sp. grew well on a mineral salts alpha-cellusose agar. one of the bacillus cereus strains and serratia marcescens ... | 1976 | 822127 |
| [degradation of 4-chlorobenzoic acid by an arthrobacter species (author's transl)]. | an arthrobacter sp. growing on 4-chlorobenzoic acid as its sole source of carbon excretes 4-hydroxygenzoic acid and protocatechuic acid into the culture medium. protocatechuic acid is further attacked by "meta"-cleavage. during growth of the arthrobacter sp. on benzoic acid cis-cis muconic acid can be isolated from the medium, suggesting the involvement of the "ortho"-cleavage pathway. the enzymes both for the "meta"- and the "ortho"-cleavage pathway are inducible. | 1976 | 1015950 |
