Genetics And Molecular Dynamics Of L,L-Diaminopimelate Aminotransferase (Dapl): An Enzyme Involved In Lysine And Peptidoglycan Biosynthesis, Lily E.J. Adams

Theses

The marked increase of bacteria that are resistant to clinically relevant antibiotics in recent years has sparked a push in the development and discovery of novel antibiotics. Complementary to this, the identification of novel antibiotic targets is also of great interest. The lysine biosynthesis pathway is an ideal candidate for these efforts because its product is an essential amino acid. Lysine cannot be synthesized by humans and thus poses minimal risk of side effects if synthesis is targeted. The penultimate product in the lysine biosynthesis pathway, meso-DAP, is also a key component of the gram-negative bacterial cell wall peptidoglycan layer. …

A Modified Rcm Medium For The Growth Of Lactobacillus Bulgaricus, Ayowole Caleb Oyeniran

Theses

In this study, we modified reinforced clostridial medium (RCM) to selectively enumerate and isolate Lactobacillus bulgaricus, a probiotic and an important starter culture in the dairy industry. The disparity in the reported carbohydrate fermentation pattern of L. bulgaricus was used to develop a growth medium not only selective for L. bulgaricus but significantly inhibitory to the growth of other lactic acid bacteria. A recently modified RCM (mRCM) was optimized for this study by the addition of 0.5% fructose, 0.5% dextrose, 1% maltose and 0.25% sodium pyruvate while replacing lactose as a carbohydrate source.

A Geometric Approach For Global Stability Of A Predator-Prey Model With An Ivlev-Type Functional Response, Soniykha Dhevi Murukan

Theses

In this paper, using a geometric approach, we study the global stability for a class of predator-prey model with an Ivlev-type functional response. We obtained this by sufficient conditions on the systems parameters, which guarantee that the positive equilibrium point of the presented system is globally asymptotically stable. Our results improve the previously obtained results from Xiaoqin Wang and Huihai Ma [1]. We conjecture that the local and global stability of the positive equilibrium are equivalent. Our conjecture is supported by numerical simulations. The theoretical proof will be our future research effort.

Evaluation Of Alternative Valorization Options For Institutional And Industrial Food Wastes, Swati Hegde

Theses

In recent years many countries and several regions in the United States have passed legislation on banning landfilling of organic waste. It is a well-known fact that organic wastes, including food scraps, generate methane under anaerobic landfill environments and contribute significantly to global warming. As more regions are mandated to follow the landfill ban, there is an increasing demand for alternative technologies for the disposal, treatment and upcycling of food wastes. Disposal and treatment may not result in any value-added products and hence are not the most efficient ways to manage food waste. As food waste has a high energy …

The Effects Of Density Gradients On The Distribution And Behavior Of Copepods, Connor Cayson

Theses

Observations of fine-scale behavioral dynamics of zooplankton may shed insight into much larger-scale ecosystem patterns and phenomena. Some zooplankton, such as copepods, are known to aggregate near density gradients; however, it is not clear the extent to which density gradients alone affect copepod distribution and behavior, since these gradients are often associated with phytoplankton layers. In this study, we investigated the behavior of Calanus pacificus in response to salinity gradients through laboratory experiments observed with high-resolution video and analyzed using computational techniques. Image data were collected using two cameras recording continuously for a duration of 30 minutes or more, allowing …

Succession Of An Upland Oak/Hickory Forest In The Central Hardwood Region, Nathan Hoover

Theses

For the last 9,000-10,000 years the Central Hardwood Region (CHR) has been primarily composed of a mosaic of mesophytic communities in climax and communities of successional forest types dominated by oak (Quercus Linnaeus) and hickory (Carya Nuttall). Shade intolerant oak/hickory dominated forest types have been maintained by natural disturbance processes in synergy with anthropogenic causes, resulting in a large composition of communities which are neither at climatic nor edaphic climax. Reduction in fire events, thinning, forest grazing, and other disturbance processes over the last 80-100 years have coincided with decreased regeneration of shade intolerant species due to lack of adequate …

Macrophomina phaseolina (Tassi) Goid., is a soilborne fungus that causes charcoal rot in over 500 plant species including Zea mays L. and Glycine max (L.) Merr. The pathogen is present in most soybean growing regions of the United States. Infection in soybean can occur after emergence and throughout the vegetative growth stages in a range of environmental conditions. The syndrome is manifest during periods of hot and dry conditions during the reproductive states of the crop. Management options are lacking and consist of avoidance and irrigating crops to lessen the damage caused by the pathogen. Fluopyram is a succinate dehydrogenase …

Effects Of Fullerenes On A Freshwater Benthic Community: Toxicity And Implications For Ecological Functions And Services, Sarah Ponte Cabral

Theses

Production of engineered carbon-based nanomaterials (CNM) is rising, with increased risk of release to the environment during production, transportation, use, and disposal. This trend highlights a need to understand potential impacts of CNM on the natural environment. Fullerenes (n-C60) are insoluble in water, and form aggregates that settle quickly, suggesting higher relative vulnerability of aquatic benthic ecosystems. This study aimed to determine eco-toxicity of fullerene and its functionalized derivatives on functionally representative benthic organisms, and evaluate how the potential lethal and sub-lethal effects of fullerene on these organisms indirectly impact benthic ecosystem function, including decomposition, primary productivity and nutrient cycling. …

Impact Of Snap Fruit And Vegetable Incentive Programs: An Analysis Of Usda Fini Projects, Katherine Engel

Theses

As diet-related chronic diseases continue to jeopardize public health in the United States, improving the dietary quality of Supplemental Nutrition Assistance Program (SNAP) participants is essential. One strategy that has been proposed as a means of doing so is utilizing fruit and vegetable incentives. Incentives serve to lower the cost of these foods for participants and thus theoretically encourage and enable them to purchase and consume more fruits and vegetables. The existing research indicates that incentives are an effective approach for increasing fruit and vegetable purchase and consumption. However, there is lack of research on the factors that influence the …
