Sweetpotato Storage Root Rots: Flooding-Associated Bacterial Soft Rot Caused By Clostridium Spp. And Infection By Fungal End Rot Pathogens Prior To Harvest, Washington Luis Da Silva
LSU Master's Theses
Sweetpotato production in the southern United States is being threatened by a soft rot that develops in storage roots when fields are flooded and by an important post-harvest disease caused mainly by the fungi Fusarium solani and Macrophomina phaseolina. To identify the pathogens responsible for development of the soft rot, samples were collected from storage roots with soft rot from intentionally flooded fields and decayed tissue was streaked on plates of nutrient dextrose agar plus 0.05% cysteine and incubated anaerobically. Two distinct groups of Gram positive strict anaerobic bacteria were re-isolated from rotting storage roots. Endospores were observed in all …

LSU Master's Theses
Phakopsora pachyrhizi, the causal agent of Asian soybean rust (ASR), has the potential to cause severe yield losses as all United States commercial soybean varieties are susceptible. In this study, 10 soybean recombinant inbred line (RIL) derived sibling lines of two populations (RN06-32-2 and RN06-16-1) were evaluated for differences in response to infection by P. pachyrhizi. These lines, which had previously shown differential responses to Florida soybean rust isolates, were evaluated using Louisiana soybean rust isolates under both detached leaf assay and greenhouse in planta inoculation conditions. Sibling lines showed significant differences in response to P. pachyrhizi infection under both …
Effect Of Bitterness Blockers And Salt Substitutes On The Quality Of Low Sodium White Cheddar Cheese, Kennet Mariano Carabante
Effect Of Bitterness Blockers And Salt Substitutes On The Quality Of Low Sodium White Cheddar Cheese, Kennet Mariano Carabante
LSU Master's Theses
Reducing added salt in processed foods is one of the major challenges facing food industry worldwide. Salt (NaCl) replacement in a Cheddar cheese has been successfully achieved up to 25%, which qualifies it as “reduced sodium”. However, a low sodium cheddar cheese (less than 140 mg Na/ 50 g cheese) requires at least 50% of salt reduction. Bitterness is one obstacle for development of an acceptable low sodium cheddar cheese. In this study, sensory optimization of low sodium white cheddar cheese was performed. A 3-component mixture design was used: NaCl (30-60%), KCl (45-65%) and glycine (5-10%). A fixed level of …

Determination Of Cane Berry Pomaces Benefits Through In Vitro Model For Human Colonic Fermentation, M'Famara Goita
Determination Of Cane Berry Pomaces Benefits Through In Vitro Model For Human Colonic Fermentation, M'Famara Goita
LSU Master's Theses
Cane berry pomaces have traditionally been considered waste products with little or no value. Yet these pomaces’ high levels of phenolic compounds such as anthocyanins, is a good source of dietary fiber. Because the pomaces are low in sugar and rich in fiber and dietary antioxidants, they have potential as food ingredients for the health food market. The pomace delivers health benefits associated with high fiber and the antioxidant polyphenolic compounds associated with whole fruits and juices without the high sugar content. Some dietary fibers are substrates for anaerobic fermentation by the microbiome in the lower gastrointestinal (GI) tract. The …
Psychological Biases Affect Hedonic Ratings, Wannita Jirangrat
Psychological Biases Affect Hedonic Ratings, Wannita Jirangrat
LSU Doctoral Dissertations
Psychological biases in consumer testing may lead to misinterpretation of results and lower experimental power. Reports on various hedonic scales associated with psychological biases induced by sample presentation are limited in the literature. An appropriate experimental protocol could enable sensory scientists to accurately determine if a product is more or less liked. Overall, in this study some drawbacks of hedonic scales were revealed and some recommendations were made under specific circumstances. A more powerful design (SPRCBD) helped minimize positional and First Serving Order (FSO) biases in consumer tests by extracting more explained variances, resulting in decreased Type-II error in the …
Perceptions Of The Motivational Climate And Gender Class Structure In Physical Education, Lauren E. Delgado
Perceptions Of The Motivational Climate And Gender Class Structure In Physical Education, Lauren E. Delgado
LSU Master's Theses
Many children do not engage in the recommended levels of physical activity, and they ten to become even less active during adolescence. Girls are less active then boys, and it is important to explore ways that physical education teachers can foster girls’ motivation to be more physically active. The specific research questions for this study were: (a) How does gender class structure affect girls’ perception of the motivational climate?; and (b) How do girls’ views of the motivation climate in different gender class structures relate to intentions to participate in physical activity outside of physical education? A phenomenological framework guided …
The Use Of Duddingtonia Flagrans For Gastrointestinal Parasitic Nematode Control In Feces Of Exotic Artiodactylids At Disney's Animal Kingdom®, Jenna Terry
LSU Master's Theses
Gastrointestinal nematodes (GIN) are parasites of major concern for domestic and exotic ruminant species around the world. In the past, zoological facilities used anthelmintics as their primary control method. Challenges in accurate dosing and administration of anthelmintics to exotic hoofstock contributed to the development of resistant nematode populations in zoological settings. The historic dependency on anthelmintics to control GIN populations is no longer an option. Biological alternatives are urgently needed, in both exotic and domestic ruminants, in the war against resistance. One such alternative is the use of the nematophagous fungus, Duddingtonia flagrans. Three independent studies were conducted: A nine …

LSU Master's Theses
Among the variety of pathogens of cotton (Gossypium hirsutum), nematodes play a major role in reducing yield. Across the U.S. cotton belt, millions of dollars are lost annually due to nematode infestation. In the Mid-South and Southeast United States, root-knot nematode (Meloidogyne incognita) and reniform nematode (Rotylenchulus reniformis) are responsible for the highest percentage of damage. Crop rotation and nematicides are currently the most commonly used management strategies for nematode management. Soil fertility, which has a direct effect on plant growth, is also known to influence disease severity. Therefore, soil fertility would be an additional factor to consider for management …
Effects Of Different Weaning Management Strategies On Preconditioning Performance, Haptoglobin Serum Levels, Feedlot Morbidity, And Carcass Characteristics, Jake Everitt Anderson
Effects Of Different Weaning Management Strategies On Preconditioning Performance, Haptoglobin Serum Levels, Feedlot Morbidity, And Carcass Characteristics, Jake Everitt Anderson
LSU Master's Theses
Weaning, one of the first major stressors encountered by the calf, has a negative effect on the immune system and increases the likelihood of infection of novel pathogens such as those that cause bovine respiratory disease. Fenceline contact at weaning has been shown to reduce the stress on the calf during the time following maternal separation. Preconditioning programs have been shown to reduce feedlot morbidity and mortality. Combining these two management practices could reduce the length of time calves need to be held in a preconditioning program. A multi-year study was conducted to evaluate if fenceline weaning will allow for …
Potential Roles Of Wrky Transcription Factors In Resistance To Aspergillus Flavus Colonization Of Immature Maize Kernels, Jake Clayton Fountain
Potential Roles Of Wrky Transcription Factors In Resistance To Aspergillus Flavus Colonization Of Immature Maize Kernels, Jake Clayton Fountain
LSU Master's Theses
The infection and colonization of maize (Zea mays L.) by the necrotrophic fungal pathogen Aspergillus flavus results in contamination of kernel tissues with carcinogenic mycotoxins known as aflatoxins, resulting in severe economic losses as well as negative effects on human and animal health. Resistance to A. flavus is mediated by both inducible and constitutively expressed defense proteins; however the mechanism regulating the expression of these defenses is poorly understood. This study examined the potential roles of six maize WRKY transcription factors, ZmWRKY19, ZmWRKY21, ZmWRKY53, ZmWRKY53.1, ZmWRKY67, and ZmWRKY68, in regulating defense responses against …

Results from viscosity analysis showed significantly low peak viscosity when rice starch was combined with 1.0% stearic acid and 6% lysine without any pH adjustment; within 0.6%-1.0% of stearic acid and 6% of lysine addition, there was a linear regression relationship between peak viscosity and the level of stearic acid. Similar pasting curves were found in rice starch with 1.0% stearic acid and 6% glutamine, or 6% cysteine, or 6% glycine in …
Mathematical And Computer-Based Models For Optimizing Microwave Heating Processes Of Frozen Oysters, Jie Zhang
Mathematical And Computer-Based Models For Optimizing Microwave Heating Processes Of Frozen Oysters, Jie Zhang
LSU Doctoral Dissertations
Consumers with full-time jobs prefer microwavable-frozen-meals for convenience when lack time to cook. Microwaves do not require a medium for heat transfer and provide quick heating even in low thermal conductivity foods, which does not occur in conventional heating. The main problem in utilizing microwave-heating for cooking is the non-uniform temperature distribution in foods which may result in insufficient lethality of microorganisms in some part. This non-uniformity can be due to a number of factors including composition and geometry of food. The objectives of this study were to develop a mathematical-model based on Maxwell¡¯s equations for predicting the temperature distribution …

Physical Self-Concept And Gender : The Role Of Frame Of Reference And Social Comparison Among Adolescent Females, Emily Kristin Beasley
LSU Doctoral Dissertations
Quality physical education can positively influence students’ emotional development, specifically their perceptions of competence, self-esteem, and self-concept. Unfortunately, girls often become less engaged and involved in physical education as they grow older and consistently report lower physical self-concepts than males. Physical self-concept is associated with multiple positive outcomes, yet there is only speculation addressing why females report lower physical self-concepts than males in physical education. The overall purpose of this dissertation was to investigate potential explanations for gender discrepancies in physical self-concept among physical education students. One qualitative and one quantitative research study was conducted to address this issue. The …
A Novel System To Study Seed Recalcitrance And Dormancy - Comparative Proteomics Between Two Spartina Species, Yi Wang
LSU Doctoral Dissertations
Spartina alterniflora is a dominant salt marsh cordgrass along the U.S. Atlantic and Gulf coasts, and the species is widely used for wetland restoration in Louisiana. S. alterniflora seeds are shed dormant from the mother plant. However, long-term preservation of S. alterniflora seeds is challenging because the seeds are recalcitrant, losing viability when dried below 45% water content. In this dissertation, I investigated the following three aspects of S. alterniflora: recalcitrance, dormancy release by cold stratification and the effect of drying temperature on the critical water content. Comparative proteomics between S. alterniflora and orthodox, desiccation tolerant Spartina pectinata seeds identified …
Integrated Functional Anlaysis Of Quorum-Sensing In The Rice Pathogenic Bacterium Burkholderia Glumae, Ruoxi Chen
Integrated Functional Anlaysis Of Quorum-Sensing In The Rice Pathogenic Bacterium Burkholderia Glumae, Ruoxi Chen
LSU Doctoral Dissertations
Quorum sensing (QS) is a cell-to-cell communication mechanism that allows bacterial cells to collectively behave like a multicellular organism. It regulates the expression of toxoflavin, one of the major virulence factors of the rice pathogen, Burkholderia glumae. The QS system of B. glumae is mediated by the core genes, tofI and tofR. N-octanoyl-L-homoserine lactone, the primary QS signal molecule of B. glumae, is synthesized by tofI and binds to the cognate receptor tofR at the quorum point. However, tofI and tofR null mutants produce toxoflavin in certain growth conditions, indicating the presence of tofI- and tofR-independent pathways for toxoflavin production. …

An Etho-Conventional Decision-Making Model For Sport Managers, Adam G. Pfleegor
An Etho-Conventional Decision-Making Model For Sport Managers, Adam G. Pfleegor
LSU Doctoral Dissertations
The need for an ethically conscious sport management workforce is evident in contemporary athletics (Simon, 2010). As the complexities of regulations continue to increase, the intricacy of ethical-decisions faced by managers similarly intensifies. Interestingly, future sport managers are rarely prepared with appropriate ethical decision-making education (Malloy & Zakus, 1995). This lack of education is problematic due to the far-reaching implications that managerial decision-makers have on firms. The aim of this investigation was to develop a novel ethical decision-making model for sport managers that can be practically implemented to resolve ethical dilemmas that they may encounter on a daily basis. The …
Environmental Kuznets Curve In Water Pollution: A Semiparametric Approach, Mahesh Pandit
Environmental Kuznets Curve In Water Pollution: A Semiparametric Approach, Mahesh Pandit
LSU Doctoral Dissertations
The relationship between pollution and per capita income generally appears as an inverted U-shaped curve. This inverted U-shaped curve is known as the environmental Kuznets curve (EKC). The shape of the curve, however, is very sensitive to the data, location and pollutant considered in the analysis. Since the early 1990s, there has been an exponential growth in the number of empirical studies in this field, but many refute the inverted U-shaped nature of the curve for pollutants across different time periods and geographical regions. This has generated an increased interest in developing a more flexible functional form for model specification …
Factors Influencing Glycogen Branching Enzyme Activity In Mouse Liver, Scott Fuller
Factors Influencing Glycogen Branching Enzyme Activity In Mouse Liver, Scott Fuller
LSU Doctoral Dissertations
Glycogen is the storage polysaccharide in a spectrum of organisms ranging from yeast to humans. Glycogen has a highly branched structure somewhat resembling a tree or shrub, with the branch points formed by glucose molecules being joined by α 1,6-glycosidic linkages. These linkages are formed by the action of branching enzyme. Branching of glycogen is critical to health, with a lack of branching causing glycogen storage disease type IV, which is fatal in humans by age 2. While glycogen branching enzyme has been studied in clinical medicine, modulation of the enzyme has received comparatively little attention. This dissertation undertook three …
Reduced Sodium Delivery Through Submicronization Of Sodium Chloride, Its Use In The Manufacture Of Surface Salted Cheese Crackers And The Evaluation Of Physico-Chemical, Microbiological And Sensory Characteristics Of Cheese Crackers, Marvin L. Moncada-Reyes
LSU Doctoral Dissertations
Reducing the particle size of sodium chloride crystal would increase its dissolution rate leading to a more efficient transfer of the ions to the taste buds and hence perhaps a saltier perception of foods. The objective of this study was to develop submicrosalt by using a nanospray drying method, its use in surface salted cheese crackers and evaluating their physico-chemical, microbiological and sensory characteristics. The cheese cracker treatments consisted of 3 different salt sizes (regular, microsalt and submicrosalt) and 3 different concentrations (2, 1.5 and 1%). The 9 (3 sizes x 3 concentrations) different cheese cracker treatments were tested for …
