Iron Acquisition In Rhodococcus Erythropolis Strain Igts8: Characterization Of A Mutant Strain That Over Produces Siderophore., Melanie Anne Pratt

Electronic Theses and Dissertations

Iron is an essential nutrient for most bacteria because enzymes like nitrate reductase and cytochromes use it as a cofactor. However, in most aerobic, neutral pH environments, iron is essentially insoluble and not easily available for bacteria to use. Many bacteria respond to this problem by releasing small organic compounds called siderophores that bind and effectively solubilize iron so that it can be transported into the cell for growth. The focus of this study was to learn more about the iron acquisition and especially the transport of iron by the soil bacterium Rhodococcus erythropolis. To fulfill this aim, mutant …

Studies Of Surfactants Effect On Riboflavin Fluorescence And Its Determination In Commercial Food Products And Vitamin Tablets., William Emmanuel Ghann

Electronic Theses and Dissertations

A simple and economical fluorometer using blue LEDs excitation sources and simple PMT detection had been built, assembled, optimized, and employed for measurement of fluorescence from riboflavin (vitamin B₂). Surfactants have been known to enhance the intensity of fluorescence of fluorescent compounds. Fluorescence analysis of riboflavin in the presence of various anionic, cationic, and nonionic surfactants was also conducted to determine if they could improve analysis. However, the surfactants employed did not seem to have any meaningful enhancement; in fact, some actually diminished the fluorescence intensity of riboflavin. The procedure was linear for riboflavin from 0.01 to 2.5 …

Women, Art, And Community: A Proposal For A Non-Profit Pottery Program In Appalachia., Lahla K. Deakins

Electronic Theses and Dissertations

Many Appalachian women are creative individuals who enjoy making and sharing quilts, songs, paintings, poetry, and other art. However, many women in rural areas of Central Appalachia lack access to basic resources because of poverty.

While many agencies help poor women find shelter, clothing, and food, there are few that help them find their creative voices. I assert that women who are given the tools to practice creative expression can overcome the mental oppression of poverty to become self-assured individuals who benefit their communities.

This thesis examines the socioeconomic condition of women in Central Appalachia and the positive impacts of …
