  • Isolation and characteristics of the DNA from nuclear polyhedrosis virus

    Creator:
    Carnegie, John William
    Abstract:
    The genome of the nuclear polyhedrosis virus which infects the larvae of the tussock moth, the lepidopteran, Hemerocampa pseudotsugata, was isolated, identified as deoxyribonucleic acid, and characterized in terms of its physical and biological properties. An isolation procedure for the viral DNA was established which consisted of the following steps:...

  • Materials associated with the DNA fraction of Bacillus subtilis W168

    Creator:
    Laudermilk, Patricia Joan
    Abstract:
    The purpose of this research was to determine if a basic protein was associated with the DNA of Bacillus subtilis W168, and to determine if there was a difference in the amount and type of protein associated with the DNA at different times during the growth cycle of the organism....

  • The association of DNA with other cellular materials in Escherichia coli lysates

    Creator:
    Porter, Bruce Wallace
    Abstract:
    The association of other materials with DNA has been studied extensively in higher organisms and more recently in bacteria. However, investigation of these complexes in bacteria have for the most part been restricted to the study of a specific function this association may serve, or a specific kind of association....

  • Significance of pigments in radiation resistance of Micrococcus radiodurans

    Creator:
    Krabbenhoft, Kenneth Louis
    Abstract:
    An ecological study of a microorganism similar to that isolated in 1956 and designated as Micrococcus radiodurans indicated that the organism could be isolated from several different environments. By taking advantage of its radio-resistivity, high levels of gamma radiation were used in the isolation procedures to inactivate most of the...

  • Characterization of the Oregon sockeye salmon virus

    Creator:
    Wingfield, William Harry
    Abstract:
    Characterization of a virus requires that its physical, biochemical and biological properties be determined. In this study the Oregon sockeye salmon virus was characterized. It was isolated in the fall of 1958 from juvenile sockeye salmon, Oncorhynchus nerka, being reared at the Oregon Fish Commission's Willamette River Hatchery. When inoculated...

  • A comparison of radiation induced lipid changes in Micrococcus radiodurans, Sarcina lutea, and Pseudomonas aeruginosa

    Creator:
    Ley, Ronald Douglas
    Abstract:
    Quantity variations in pigments and lipid classes were determined following γ-irradiation of Micrococcus radiodurans, Sarcina lutea, and Pseudomonas aeruginosa. Pigmentation was determined by extraction with organic solvents and measured as optical density at 475 mμ for M. radiodurans and S. lutea, and 410 mμ for Ps. E aetuginosa. Pigments of...

  • Susceptibility of two salmonid fish cell lines to two viruses from fish and two from homothermic animals

    Creator:
    Nims, Linda Jean
    Abstract:
    This thesis describes the viral susceptibility of two cell cultures established from embryonic tissue of salmonid fish, chinook salmon line CHSE-114 and steelhead trout line STE-137. The viruses used were Oregon sockeye salmon virus (OSV), Sacramento River chinook disease virus (SRCD), Western equine encephalitis virus (WEE) and Newcastle disease virus...

  • Analysis of segregants of F'gal heterogenotes in Escherichia coli

    Creator:
    Kurahara, Carole Mahaney
    Abstract:
    The purpose of this study was to isolate and characterize any segregants of the heterogenotes formed from sexduction by an F' donor. Following the mating of F' W4520, carrying an F' gal₁⁺ gal₂⁺ factor, with W3350, a gal₁⁻ gal₂⁻ recipient, a number of recombinant clones were picked and examined for...

  • Thermally induced leakage and viability studies in an obligate psychrophilic marine bacterium

    Creator:
    Kenis, Paul Robert
    Abstract:
    Vibrio marinus MP-1, an obligate psychrophilic marine bacterium, was severely damaged when heat-shocked in the presence of nutrients. Thermally induced leakage materials from cells tested for in the medium were 260 mμ absorbing material (nucleic acids), orcinol reacting material (RNA), ninhydrin reacting material (amino acids), protein, malic dehydrogenase, and glucose-6-phosphate...

  • Temperature-salinity effects on net protein synthesis and viability of Vibrio marinus mp-1, an obligately psychrophilic marine bacterium

    Creator:
    Cooper, Mary Faith
    Abstract:
    The relationship of temperature and salinity to protein synthesis was determined for cells of Vibrio marinus, MP-1. Protein synthesis was measured by the incorporation of radioactive proline into hot trichloroacetic acid precipitable material. At all salinities protein synthesis occurred at 15°C and 20°C but not at 25°C. The critical temperature...
