  • A multiscale approach to bacterial adhesion

    Creator:
    Ostvar, Sassan
    Abstract:
    This work is an attempt to develop a simple physical description for the initial interactions between a bacterial cell and a substrate surface. This is done by adopting a view that regards bacterial surface biomolecules not as secondary and add-on contributors to the potential energy function that characterizes the overall...

  • Bacterial hydrophobicity : assessment techniques, applications and extension to colloids

    Creator:
    Saini, Gaurav
    Abstract:
    This research details laboratory assessment of bacterial hydrophobicity, variations in bacterial adhesion properties with growth and extended starvation as well as extension of this assay to colloidal hydrophobicity measurement. Hydrophobicity is an integral component of surface interactions and has been studied extensively for its role in a number of engineering...

  • Binding of bacterial lipopolysaccharide by the cationic amphiphilic peptide WLBU2 at interfaces

    Creator:
    Ryder, Matthew P.
    Abstract:
    Passage of blood through a sorbent device for removal of bacteria and endotoxin by specific binding with immobilized, membrane-active, bactericidal peptides holds promise for treating severe blood infections. Peptide insertion in the target membrane and stable binding is desirable, while membrane disruption and release of degradation products to the circulating...

  • Characterization of the feedback between the instructor and student teams engaged in a virtual bioreactor laboratory project

    Creator:
    Whinnery, Jaynie L.
    Abstract:
    This thesis characterizes the feedback between the instructor and student teams engaged in a Virtual Bioreactor (VBioR) Laboratory Project. The project allows senior-level chemical, biological, and environmental engineering students to apply their developing knowledge and skills in an industrially situated process optimization project. Feedback is an important tool for instructors...

  • Computational Investigation and Prediction of Mechanisms and Stereocontrol in Complex Organic Reactions

    Creator:
    Pattawong, Ommidala
    Abstract:
    Complex organic transformations, such as the addition of pyrrole to ketene using planar chiral organocatalyst (*PPY), the four-component anhydride- Manniach reactions, and the site-selective desymmetrization of meso-1,2-diol, are remarkable synthetic reactions that provide high yield and high selectivity. However, the exact mechanism and origins of stereocontrol for theses synthetic organic...

  • Effects of silver ions and nanoparticles on suspended cells and biofilms of Nitrosomonas europaea

    Creator:
    Barker, Leila Kelly
    Abstract:
    Silver nanoparticles are increasingly being incorporated into consumer products due to their broad-spectrum antimicrobial properties. The resulting influx of silver nanoparticles into wastewater may pose a threat to bacteria involved in biological wastewater treatment. Ammonia-oxidizing bacteria, which convert ammonia to nitrite in the first step of nitrification, are highly sensitive...

  • Experimental approach for the determination of lignin modification by manganese peroxidase

    Creator:
    Goby, Jeffrey D.
    Abstract:
    Degradation of lignin to simpler compounds is desirable for removing residual lignin during paper manufacture and accessing biomass carbohydrates for biofuel production, among other purposes. Lignin transformation using enzymes found in white rot fungi, some of nature's most efficient lignin-degrading organisms, offers a more environmentally benign, selective, and possibly less...

  • Novel Approaches to Evaluate the Environmental Impacts of Nanomaterials

    Creator:
    Wu, Fan
    Abstract:
    Numerous studies have shown that some nanomaterials are highly toxic to aquatic organisms and can potentially disrupt overall community health; however, current methods to evaluate the nanomaterials environmental impacts rarely consider the environmental realism or provide sufficient detail on the impact at the community level. Here we demonstrate three approaches...

  • Removal of E. coli with alternative media Biosand filters

    Creator:
    Fulton, Nathan J.
    Abstract:
    When Biosand filters cannot be constructed with crushed quarry rock due to resource limitations, a suitable alternative filter media is needed. In this research, two crushed quarry rock alternatives were examined. Three bench-scale Biosand filters with crushed rock, beach sand, and heat-treated beach sand media were simultaneously dosed with Willamette...

  • Solution-based nanomaterials and thin films for next generation electronics

    Creator:
    Oleksak, Richard P.
    Abstract:
    Nanomaterials are expected to enable significant advances in several technological fields in coming years. Among them, electronics has emerged as one of the most likely benefactors from the ability to control matter on the nanometer-scale. For many electronic devices synthesized nanomaterials must be integrated into thin film structures. Vapor-based deposition...
