Characteristics Of Yogurt And Culture Bacteria As Affected By Ingredients That Help Treat Leaky Gut, Ricardo Jose Santos Aleman

LSU Doctoral Dissertations

At least 100 million people have leaky gut syndrome. This syndrome is associated with multiple health problems such as diabetes, celiac disease, asthma, multiple sclerosis, and inflammatory bowel disease, costing more than $3 billion per year to treat. L-Glutamine, quercetin, slippery elm bark, marshmallow root, N-acetyl-d-glucosamine (NAG), licorice root, maitake mushrooms, and zinc orotate have been reported to help treat leaky gut.

The objectives were to explore the characteristics of yogurt and culture bacteria as affected by ingredients that help treat leaky gut. In yogurt, the pH, titratable acidity, syneresis, viscosity, color, Streptococcus thermophilus, Lactobacillus bulgaricus, yeast and mold and …

Producing Bacterial Cellulose From Coffee (Coffea Arabica) Kombucha Fermentation And Assessment Of Its Efficacy To Remove Pathogenic Bacteria From Contaminated Water And A Pollutant Dye From Aqueous Solution, Federico Bueno

LSU Doctoral Dissertations

Bacterial cellulose (BC), composed of cellulosic nanofibrils, is synthesized by a symbiotic culture of bacteria and yeast during the fermentation of coffee kombucha (CK). BC may be used as a purification agent and adsorbent. The overall goal of this project was to synthesize BC from CK fermentation and assess its efficacy in removing pathogenic bacteria from contaminated water and a pollutant dye from aqueous solution. The objectives of this study were to: (1) compare BCs that were produced from different carbohydrate substrates in the fermentation of CK, (2) characterize dried BCs produced using various drying methods, (3) evaluate BC as …

Sodium Propionate And Sodium Butyrate Promote Fatty Acid Oxidation In Hepg2 Cells Under Oxidative Stress, Kristina Jazmin Cook

LSU Doctoral Dissertations

Non-alcoholic fatty liver disease (NAFLD) is a spectrum of disturbances that includes simple steatosis, non-alcoholic steatohepatitis (NASH), fibrosis, cirrhosis, and liver cancer. NAFLD affects individuals that consume the typical Western diet consisting of high levels of fats and carbohydrates. The increase in circulating free fatty acids, palmitate and oleate, or lipopolysaccharides (LPS), induce oxidative stress and pro-inflammatory cytokine production in the liver, which all contribute to NAFLD progression. In this study, we are evaluating the mRNA expression of genes associated with fatty acid oxidation (FAO) and the protein expression of pro-inflammatory cytokines related to NAFLD using the HepG2 human liver …

In Vitro And In Vivo (Mouse Model) Investigation Of The Efficacy Of Probiotic Bacteria Lactobacillus Casei And Lactobacillus Rhamnosus Incorporated In Tomato Juice, Bennett Atta Dzandu

LSU Doctoral Dissertations

Fruit and vegetable production in Ghana were estimated at 371,811 tons in 2017 with tomatoes ranked among the top four most cultivated vegetables. The majority of the production goes to waste due to spoilage and lack of processing. Probiotics have recently gained much attention owing to claims about their potential health benefits. However, the inability of certain probiotics to survive gastric conditions remain a potential setback. Tomatoes can be processed into value added products including those fortified with probiotics. Such value-added products can be used as protectant for the delivery of probiotics to improve gut health. The objective of this …

Delivering Entrapped Lactobacillus Plantarum Ncimb 8826 With Cereal-Legume Infant-Weaning Food To Improve Children's Gastrointestinal Health, Emmanuel Kyereh

LSU Doctoral Dissertations

Diarrhea remains the second leading cause of death among children under five globally, about one in five children’s deaths are attributable to it. In recent years,’ probiotics have been used as an alternative therapy measure to manage the situation. A promising delivery method that entraps probiotics in infant formula may help prevent or reduce diarrhea. The overall objectives of this study were to deliver entrapped Lactobacillus Plantarum NCIMB 8826 with maize-legume fortified complementary weaning food to reduce diarrhea and improve the gut microbiota. Both in vitro and in vivo models were used in this study and a mouse (C57BL/6 mice …

Discovering Potential Protein, Carbohydrate, And Lipid Based Food Ingredients In A Co-Culture Of Microalgae, Chelsea Tyus

LSU Doctoral Dissertations

Louisiana Native Co-Culture of Microalgae (Chlorella Vulgaris L. and Cyanobacteria Leptolyngbya sp.) (CCA) was studied. CCA is a viable coculture for further investigation as a food component. This research characterized the proteins, carbohydrates, and lipids present in CCA. Algae cultivation parameters were controlled and analyzed. Treatment (Trt) 1 was CCA grown in cultures exposed to average scalar irradiance (ASI) of 1041 ± 269.18 μmol m-2 s-1 PAR and trt 2 was CCA grown in cultures exposed to ASI of 430 ± 96.03 μmol m-2 s-1 PAR. The trt (irradiance exposure) had the desired response on CCA species ratio Trt …
