Impact of lignin on efficiency of small-scale enzymatic hydrolysis of lignocellulosic biomass

Creator:: Potapchuk, Angelica
Abstract:: Energy production and consumption is a major environmental and economic concern in the world today. Biofuel produced from lignocellulosic biomass is being explored as an alternative energy source to petroleum. Lignocellulosic biomass is comprised of cellulose, hemicellulose, and lignin. To produce biofuels, lignocellulosic biomass must be broken down to expose...

Biochar as a cover for dairy manure lagoons: reducing odor and gas emissions while capturing nutrients

Creator:: Dougherty, Brian W.
Abstract:: Liquid manure lagoons are known to be sources of odor and environmentally damaging gas emissions. Land application of the manure slurry after storage can lead to detrimental nutrient runoff and leaching. Floating lagoon covers (biocovers) are one option for reducing emissions, but to date they have only been used to...

Light quality manipulation for the solvent extraction of phycocyanin from Oregon freshwater cyanobacteria

Creator:: Gregor, Katelin
Abstract:: Phycocyanin, a photosynthetic pigment-protein complex produced by cyanobacteria, has critical value in the medical field at high purity. Costs associated with the extraction of this pigment are high, emphasizing the importance of optimal growth conditions. The aim of this study was to investigate potential commercial producers of phycocyanin by evaluating...

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...

Understanding polycyclic aromatic hydrocarbon (PAH) toxicity and inflammation in human bronchial epithelial cells

Creator:: Valdez, Teresa
Abstract:: There is increased emphasis on understanding cumulative risk from the combined effects of chemical and non-chemical stressors as it relates to public health. Recent animal studies have identified pulmonary inflammation as a possible modifier and risk factor for chemical toxicity in the lung after exposure to inhaled pollutants; however, little...

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),...

Endometrial Inflammatory Cytokine Expression in Postpartum Beef Heifers Following Platelet Rich Plasma Treatment

Creator:: Perez, Victor O.
Abstract:: Background: Uterine inflammation (e.g., endometritis) causes negative economic effects in the beef industry by reducing reproductive performance. Current treatments for endometritis in beef cattle involve hormones and antibiotics, which can be expensive and are often ineffective. The endometrial immune response regulates the release of cytokines and chemokines in response to...

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...

A Comparative Analysis of Mercury and Lead in Sindoor from the U.S. and Bangladesh

Creator:: Breen, Anna K.
Abstract:: Heavy metals have historically been popular for use in cosmetics manufacturing due to the colorful pigmentation of heavy metal compounds. In the case of sindoor, a cosmetic used by married Hindu women for religious purposes, mercury sulfide, lead tetroxide, and lead chromate are compounds suspected to still be involved in...
