We determined the effects of a commercial proprietary formulation of polysaccharide hydrolyzing enzymes on ethanol fermentation performance, oil partitioning and recovery, and quality of dried distillers grains with solubles (DDGS) on a 1.5-L and 50-L fermentation scale. The enzyme was added at the start of fermentation. Whole beer was subjected to beer well incubation, distillation, and separation of thin stillage from the wet cake. The enzyme promoted faster ethanol production without affecting the final ethanol yield. The enzyme treatments resulted in 8–18% higher wet yield of thin stillage than the control, 13–21% of oil increase in thin ...
Effects Of Glycerin Antifreeze On Cpvc, 2016 The Madison Group
Effects Of Glycerin Antifreeze On Cpvc, Paul J. Gramann, Javier C. Cruz, David A. Grewell, Melissa Montablo-Lomboy, Tong Wang Professor
There are multiple applications where chlorinated poly(vinyl chloride) (CPVC) may come in contact with glycerin. One common application is in fire suppression systems that could be subjected to subfreezing temperatures. Chlorinated poly(vinyl chloride) is increasingly being used for these systems in place of metal because of its many advantages, including the ease of installation, weight reduction, cost benefits and chemical resistance. When CPVC piping is used in an area that has the potential to freeze, an antifreeze solution must be used in the fire suppression systems to suppress the freezing temperature of the water and reduce possibility of ...

Brindley, Choonseok Oh, Jeffrey D. Neighbors, David F. Wiemer, Nickolas Wills, Susan L. Carpenter, Catherine C. Hauck, Patricia A. Murphy, Mark P. Widrlechner, Kathleen Delate, Ganesh Kumar, George A. Kraus, Ludmila Rizshsky, Basil J. Nikolau
Light-dependent activities against enveloped viruses in St. John's Wort (Hypericum perforatum) extracts have been extensively studied. In contrast, light-independent antiviral activity from this species has not been investigated.
Here, we identify the light-independent inhibition of human immunodeficiency virus-1 (HIV-1) by highly purified fractions of chloroform extracts of H. perforatum. Both cytotoxicity and antiviral activity were evident in initial chloroform extracts, but bioassay-guided fractionation produced fractions that inhibited HIV-1 with little to no cytotoxicity. Separation of these two biological activities has not been reported for constituents responsible for the light-dependent antiviral activities. Antiviral activity was associated with more ...
Oxalate And Phytate Of Soy Foods, 2016 Washington State University
Oxalate And Phytate Of Soy Foods, Ismail A. Al-Wahsh, Harry T. Horner, Reid G. Palmer, Manju B. Reddy, Linda K. Massey
The consumption of foods made from soybeans is increasing because of their desirable nutritional value. However, some soy foods contain high concentrations of oxalate and/or phytate. Oxalate is a component of calcium oxalate kidney stones, whereas phytate is an inhibitor of calcium kidney stone formation. Thirty tested commercial soy foods exhibited ranges of 0.02−2.06 mg oxalate/g and 0.80−18.79 mg phytate/g. Commercial soy foods contained 2−58 mg of total oxalate per serving and 76−528 mg phytate per serving. Eighteen of 19 tofu brands and two soymilk brands contained less than ...

Programming Heart Disease: Does Poor Maternal Nutrition Alter Expression Of Cardiac Markers Of Proliferation, Hypertrophy, And Fibrosis In Offspring?, Cathy Chun
Honors Scholar Theses
Maternal malnutrition can affect fetal organogenesis, metabolic processes, and factors involved in developmental regulation. Of the many physiological effects poor maternal nutrition can induce in offspring, one of the most important organs affected is the heart. Cardiovascular disease has been associated with poor maternal diet. It also been suggested that hypertension can originate during impaired intrauterine growth and development. Hypertension can trigger hypertensive heart disease and is associated with numerous heart complications. We hypothesized that poor maternal nutrition would alter critical growth factors associated with normal heart development, specifically, insulin-like growth factor (IGF)-1, IGF-2, transforming growth factor (TGF)β ...

Human Nutrition and Hospitality Innovation Undergraduate Honors Theses
Over 30% of adults in the US are obese. A primary contributor to obesity is an unhealthy diet related to imbalanced macronutrients. Diets higher in protein (PRO) are associated with increased energy expenditure (EE) and reduced food intake. The objective of this pilot study was to determine if protein source at breakfast influences EE in young men (n=4; ages 18-35). Participants consumed three isocaloric (whey (WP), pea (PP), beef (BP); 275 kcal, 62% PRO, 23% CHO, 15% Fat) drinks in randomized, crossover design with a one-week washout period. Each test day EE, appetite, and cravings were assessed at ...
Awareness Of Biological Mechanisms Of Artificial Sweeteners And The Effects Of Increased Awareness Via Video Media On Intent To Change Dietary Habits In Traditional College-Age Students, 2016 The University of Southern Mississippi
Awareness Of Biological Mechanisms Of Artificial Sweeteners And The Effects Of Increased Awareness Via Video Media On Intent To Change Dietary Habits In Traditional College-Age Students, Cassie A. Mahler
In the past, artificial sweeteners have been touted as weight loss solutions because they theoretically do not interact with the body’s metabolism. However, new research is being done to test this theory, but what is the public awareness of these compounds’ interactions with the body? The purpose of this study is threefold: to assess the current awareness of the biological mechanisms of artificial sweeteners in traditional college-age individuals; to assess the effectiveness of video education in increasing this awareness; and to assess how the increase of this awareness might lead to intentions to change dietary habits. The study consisted ...
The Effect Of Transformed Escherichia Coli On The Mouse Intestine Microbiome: The Microbial Metabolic Enhancement Hypothesis, Bryar P. Kader
Senior Honors Theses
Metabolic disorders affect around thirty-four percent of the population in the United States. Among these disorders is lactose intolerance, which results from diminished production of the human lactase enzyme. This disorder and others like it are genetically determined and cannot be cured. However, the use of transformed bacteria implanted in the colon may provide a means by which the faulty pathway can be bypassed. To test whether transformed bacteria have the capability to aid in the digestion of normally indigestible compounds, a transformed strain of Escherichia coli overexpressing the beta-galactosidase enzyme encoded by the lacZ gene was colonized in the ...
