Evaluation Of Alkaline- And Fungal-Assisted Wet Storage Of Energycane Bagasse, Jing Cao
LSU Master's Theses
Lignocellulosic biomass is a promising renewable resource for the production of biofuels and biochemicals. Energycane is considered a lignocellulosic biomass characterized by its high fiber content and cold tolerance. It can be planted on marginal land and does not need to compete with the food supply. Wet storage in combination with sodium hydroxide (NaOH) or white-rot fungi was applied to energycane bagasse to preserve the lignocellulosic polymeric sugars (cellulose and hemicellulose) during short-term storage (60 days) and to make them accessible for conversion into biofuels and biochemicals. Alkaline-assisted wet storage was successful in preserving the biomass by minimizing microbial degradation, …

Structure And Functional Potential Of Microbial Communities In Subglacial Lake Whillans And At The Ross Ice Shelf Grounding Zone, West Antarctica, Amanda Marie Achberger
LSU Doctoral Dissertations
The abundance of liquid water found beneath the Antarctic Ice Sheet (AIS) is thought to provide a suitable habitat for microbial life. However, the thick ice sheet has posed a significant obstacle to accessing this isolated system and as a consequence, little data exists to infer ecosystem processes occurring beneath ice sheets. To address this deficit, data generated through 16S rRNA (genes and molecules) and metagenomic sequencing was used to evaluate the diversity and potential metabolic function of communities inhabiting Subglacial Lake Whillans (SLW) and the ocean basin into which it discharges (Whillans Ice Stream grounding zone; WIS-GZ). The analysis …
Metabolic Preconditioning Of Mammalian Cells: Approaches For Increasing Biostability After Desiccation, Apurva Shrihari Borcar
Metabolic Preconditioning Of Mammalian Cells: Approaches For Increasing Biostability After Desiccation, Apurva Shrihari Borcar
LSU Doctoral Dissertations
Selected species in nature are able to tolerate prolonged periods of severe water stress. Survival of cellular desiccation in these anhydrobiotic organisms is conferred by a number of mechanisms including accumulation of stabilizing solutes, such as trehalose, and expression of Late Embryogenesis Abundant (LEA) proteins. An additional feature shared by some anhydrobiotic animals is the capacity to suppress mitochondrial oxidative phosphorylation in preparation for desiccation. These mechanisms improve the physiological robustness of cells to stress. The primary aim of this dissertation is to evaluate forms of metabolic preconditioning and to test the most propitious as a means to improve desiccation …

Average berry weight was also lower in X. fastidiosa-positive plants. However, plants that …
Dietary Plant Lectins May Be An ‘Unknown Etiology’ In Parkinson’S Disease And Dietary Bioactive Compounds Affect Lifespan And Fat Storage Aspects Of Caenorhabditis Elegans, Mingming Wang
LSU Doctoral Dissertations
Dietary bioactive compounds benefit health while some might induce pathological processes. Parkinson’s disease (PD) is the second most common neurodegenerative disease. Braak and Hawkes hypothesized that the gastrointestinal tract may be a potential site of neuronal invasion by an “unknown pathogen” leading to some Parkinsonism. Neurotoxin botulinum or ricin can trans-synaptically transport in nervous system. Our hypothesis 1: dietary plant lectins might be responsible for the “unknown pathogen” causing PD. Pomegranate juice (PJ) have antioxidant and anti-obesity effects. Our hypothesis 2: PJ increases lifespan in C. elegans and reduces fat storage. Study 1: Post-feeding rhodamine or TRITC tagged dietary lectins …

The Economic Burden Of Gluten-Free Products And The Potential Of Dietary Inhibitors Of Transglutaminase-2, Kristen Kramer
The Economic Burden Of Gluten-Free Products And The Potential Of Dietary Inhibitors Of Transglutaminase-2, Kristen Kramer
LSU Master's Theses
Celiac disease (CD) is a chronic immune-mediated disease of the small intestine caused by the ingestion of gluten. Gluten presents to the intestine largely intact where it is deamidated by Transglutaminase-2 (TG2), increasing affinity for Human Leukocyte Antigen DQ2 (HLA-DQ2) and forming a complex that elicits an inflammatory response ultimately leading to villous atrophy. The only current treatment is strict adherence to a gluten-free diet, though TG2 inhibition is an attractive therapy due its central role in CD pathogenesis. Cocoa contains procyanidin-B2, theobromine and caffeine and may be capable of inhibiting TG2-induced intestinal inflammation and reduce CD symptoms. Procyanidin-B2 rich …
