Toxicity Screening of Polycyclic Aromatic Hydrocarbons (PAHs) in Primary Human Bronchial Epithelial Cells

Creator:: Amador, Samantha B.
Abstract:: Polycyclic aromatic hydrocarbons (PAHs) are a known class of chemicals that are linked to a multitude of adverse health outcomes. There are over 1,500 of these chemicals across various families and subgroups. 16 of these PAHs, known as parent PAHs, are identified by the EPA for focused risk assessment within...

Pilot study of operational parameters in microbial electrolysis cell with dark fermentation reaction

Creator:: Camplair, Mora
Abstract:: Biohydrogen production via dark fermentation (DF) and microbial electrolysis cells (MEC) demonstrate great potential for sustainable hydrogen generation. In this study, DF and MEC were coupled as a hybrid reactor and evaluated using brewery wastewater. The effect of hydraulic retention time (HRT) and buffer concentration on reactor performance were assessed...

Biosynthetic Studies of the α-Amylase Inhibitor Trestatin in Streptomyces dimorphogenes

Creator:: Demessie, Ananiya A.
Abstract:: The prevalence of obesity and diabetes in the United States and globally has been rising in the last few decades and it continues to climb. One of the causes for this increase is the over consumption of sugars and/or carbohydrates. Among medications available to treat obesity and diabetes are the...

Enhancing Protocols to Improve Consistency Across Nanotoxicology Studies

Creator:: Luker, Sabrina R.
Abstract:: In current nanotoxicology research, there is a lack of standardization in reporting of zebrafish exposure media and sonication practices. This lack of standardization in use and reporting methods has made reproducing nanoparticle (NP) toxicity results between labs a common issue. It is important to have a standardized way of reporting...

Modeling optical reflection and electric field intensity in organic semiconductor microcavities

Creator:: Munk, Rebecca
Abstract:: Organic semiconductors are a promising alternative to the traditional inorganic semiconductors, such as silicon. Organics are solution-processable, low-cost, sustainable, and have interesting optoelectronic properties. One such property is the formation of exciton-polaritons, quantum quasi-particles formed by an electron-hole pair in the semiconductor and a photon. This process can be induced...

Utilization of structure-activity-relationship for predicting chemical toxicity in primary human lung cells

Creator:: Galbreath, Amanda
Abstract:: There is a growing need to establish alternative approaches for assessing hazard from chemical exposure compared to the traditional method of animal testing. Approaches that relate chemical structure to biological activity are gaining acceptance in the field as in silico methods for characterizing and predicting chemical toxicity. In this study,...

Fungal Photonics

Creator:: Spafford, Jasper
Abstract:: The spalting fungus Scytalidium cuboideum secretes a red pigment that produces naphthoquinonic crystals that are a photonic material candidate. The molecule can pack together in different configurations resulting in amazingly different optical properties. I developed a procedure (slowly evaporating the solvent) to preferentially grow two of these configurations, which have...

Toxicity and Mutagenicity of Polycyclic Aromatic Hydrocarbons in Contaminated Soils using Mammalian In Vitro Assay

Creator:: Luker, George W.
Abstract:: There exists a growing need to establish a better in vitro model for evaluating PAH toxicity and carcinogenicity and to improve assessments of risk to human health, especially to the complex mixtures that exist in the environment. Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous environmental contaminants due to the incomplete combustion...

Partial purification of endo-1,4-β-D-glucanase I of Trichoderma reesei and use in small-scale enzymatic hydrolysis of cellulose

Creator:: Pautsch, Lindsay
Abstract:: In order to reduce the cost of lignocellulosic ethanol production, a model was previously developed to predict the amount of fermentable sugar released based on parameters concerning both biomass and enzymes. To validate this model, enzymatic hydrolysis must be carried out using individual purified cellulase enzymes. Endo-1,4-β-D-glucanase I (EG I),...

Biogas inhibition of fats, oils, and greases with varying ammonia levels

Creator:: Aranda, Ana A.
Abstract:: Biogas can be used to generate energy from a wide variety of sources. Wastewater treatment sludge is an effective source of waste to be used for generation of biogas to make energy which can be used to heat homes and run businesses. This would help decrease the use of fossil...
