  • Metagenomics and metatranscriptomics of the leaf- and root-associated microbiomes of Zostera marina and Zostera japonica

    Creator:
    Wojahn, John Michael Adrian
    Abstract:
    A great deal of research has been focused on the microbiomes of terrestrial angiosperms (flowering plants), but much less research has been performed on the microbiomes of aquatic angiosperms (Turner et al. 2013). Eelgrass beds are extremely productive ecosystems that provide habitat for many marine organisms, such as fish, shellfish,...

  • The Genomic Capabilities of Microbial Communities Track Seasonal Variation in Arctic Lagoons

    Creator:
    Baker, Kristina D.
    Abstract:
    The lagoons spanning Alaska’s Beaufort Sea coast provide a unique habitat for arctic wildlife. These lagoons and the food webs they support face extreme seasonality with nine months of ice cover followed by a spring thaw that pulses a large amount of freshwater and nutrients into the lagoons. Bacteria link...

  • Biogeochemical Processing of Freshwater Carbon in the Anthropocene

    Creator:
    Buser, Jessica Z.
    Abstract:
    Freshwater systems cycle carbon along a spatial and temporal biogeochemical continuum, across which ecosystem processes contribute to transformations of organic matter (OM). Various ecological constraints impact rates OM transformation and production and consumption of the energetic end of respiration, methane. Microbiological processing and complete reduction of carbon substrates to methane...

  • Chemical and Genetic Investigations of Toxic Freshwater Cyanobacterial Blooms for Improved Monitoring and Understanding of Lake Ecology

    Creator:
    Collart, Lindsay P.
    Abstract:
    Toxin production by cyanobacterial harmful algal blooms (cyanoHABs) in freshwater systems has lasting ecological and human impacts. Nutrients, light availability, hydrology, and microbial community composition impact the frequency and intensity of toxic cyanoHABs. Climate change will exacerbate toxic cyanoHABs, making real time and predictive monitoring a vital tool for managing...

  • Methods of identifying food poisoning staphylococci

    Creator:
    Orth, Donald Simms
    Abstract:
    Several biochemical tests were studied to determine their correlation with coagulase activity. The lysozyme test was in perfect agreement with the coagulase test for the strains studied. Mannitol fermentation and egg yolk lipase tests were in agreement with the coagulase test for 96% of the coagulase positive strains. Sheep red...

  • Studies on the fatty acid and lipid composition of Clostridium botulinum

    Creator:
    McCollough, Marian Lorraine
    Abstract:
    Routine studies of bacterial fatty acid and lipid composition, made possible by recently developed techniques, have brought about an increasing interest in the physiological significance of these compounds. The purpose of this study was to characterize the fatty acids of the vegetative cells of Clostridium botulinum 33A, as the first...

  • Factors that influence sulfide production in an estuarine environment

    Creator:
    Peterson, Paul Edward
    Abstract:
    Core samples from five sites in the Yaquina and Coos Estuary were assayed for vertical distribution of total sulfides, percent volatile solids, redox potential, particle size, total aerobic and sulfate reducing bacteria. Higher total sulfide levels were found at sites having more than four percent volatile solids, redox potential below...

  • 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...

  • A study of the fatty acids and lipids of Clostridium botulinum type B

    Creator:
    Paterno, Visitacion Asi
    Abstract:
    The difficulties encountered in working with micro-quantities of lipids have been overcome by the advent of new and improved procedures in chromatography which have made possible better fractionation and identification. Bacterial lipids because of their different lipid pattern from other life forms have stimulated much interest. Studies have been made...
