A Transcriptomic Analysis Of Salmonella Enterica Newport In Planta And After Postharvest Sanitization, Laurel Lynn Dunn Aug 2017

A Transcriptomic Analysis Of Salmonella Enterica Newport In Planta And After Postharvest Sanitization, Laurel Lynn Dunn

Doctoral Dissertations

The consumption of fresh produce is increasingly linked to incidence of foodborne illness. Pathogens including Salmonella enterica, Shiga toxigenic Escherichia coli, and Listeria monocytogenes are exposed to produce crops through direct human or animal contact, contaminated agricultural water, bioaerosols, run-off, and improperly treated compost. S. enterica has demonstrated exceptional tolerance to the stresses encountered in the environment, on plant tissue, and from postharvest antimicrobial mitigation strategies. Understanding the transcriptomic mechanisms S. enterica employs to survive these hazards is integral for the development of more effective preventive controls and post-harvest steps to prevent the pathogen from infecting consumers.


Effect Of Ultrasonication On The Physicochemical Properties Of Sorghum Kafirin And Evaluation Of Its Anti-Inflammatory Properties In Vitro, Andrew Cullen Sullivan Aug 2017

Effect Of Ultrasonication On The Physicochemical Properties Of Sorghum Kafirin And Evaluation Of Its Anti-Inflammatory Properties In Vitro, Andrew Cullen Sullivan

Masters Theses

Sorghum is one of the hardiest, most drought resistent cereal grains known to exist, providing the bulk of nutritional content for many semi-arid regions and developing countries throughout Africa and southwestern Asia. It contains dense nutritional value, but due to inhibition factors within the grain, much of these nutrients are indigestible. Access to these nutrients, which have shown to contain high contents of bioactive molecules linked to the decrease of prevalence of chronic disease, must then be facilitated before consumption. In sorghum, these molecules could include complex carbohydrates, proteins and polyphenols. The overall objective of this study was to determine ...


Comparative Chemical Characterization Of Lunasin-Enriched Preparations And Modifications Of The Inflammasomes In Vitro, Samuel James Price May 2017

Comparative Chemical Characterization Of Lunasin-Enriched Preparations And Modifications Of The Inflammasomes In Vitro, Samuel James Price

Masters Theses

Soybean (Glycine max) is one of the most cultivated crops in the world providing the population with large amounts of protein and oil. In addition to its nutritional composition, soybean also contains biologically active compounds with potential health-promoting properties. The presence of these bioactives may be responsible for the lower incidence of chronic diseases in populations that consume a significant portion of soybeans in their diet. One group of soybeanderived bioactives are bioactive peptides and proteins including lunasin, Bowman-Birk inhibitor (BBI) and Kunitz-type trypsin inhibitor (KTI). The overall objective of this research was to develop a method of preparing lunasin-enriched ...


Protein, Methionine, And Cysteine Upregulation In Phaseolus Vulgaris ‘Black Turtle Bean’ Seeds Through Sulfur Fertilization At V2 And R2 Stages Of Growth, Hannah Paige Barry May 2017

Protein, Methionine, And Cysteine Upregulation In Phaseolus Vulgaris ‘Black Turtle Bean’ Seeds Through Sulfur Fertilization At V2 And R2 Stages Of Growth, Hannah Paige Barry

Masters Theses

The purpose of this research was to increase protein, methionine, and cysteine content in Phaseolus vulgaris L., common bean in relation to the inhibitory compound tannin. Previous research has shown that sulfur fertilization increases total protein, methionine and cysteine content in various crops, but always in tandem with inhibitory compound increases. If successful, the resulting bean seed will have a better nutrient profile for malnourished populations around the world.

Heat Inactivation Kinetics Of Tulane Virus And Aichi Virus, Sukriti Ailavadi May 2017

Heat Inactivation Kinetics Of Tulane Virus And Aichi Virus, Sukriti Ailavadi

Masters Theses

Human noroviruses (HNoVs) and Aichi virus (AiV) causes significant number of gastrointestinal diseases worldwide. Tulane virus (TV), a cultivable HNoV surrogate, is used to determine control measures against HNoV. The objectives of this study were to determine the heat inactivation kinetics of TV and AiV in cell-culture media and TV in spinach using the first-order and Weibull models. TV and AiV in cell-culture media at ~7 log PFU/ml in 2-ml glass vials were heated at 50-58°C [degree Celsius] up to 10 min in a circulating water-bath. Surviving infectious viruses were enumerated by standard plaque assays using confluent host ...
