Packaging Of Genetic Material By Gene Transfer Agents (Gtas) Produced By Marine Roseobacter Species And Their Effect On Stimulating Bacterial Growth, Shahd Bader Aljandal

USF Tampa Graduate Theses and Dissertations

Horizontal gene transfer is one of the most important mechanisms for prokaryotic genome innovation and evolution. Gene Transfer Agents (GTAs) are phage-like particles that package small fragments of the genome of a GTA-producing bacterial cell. GTA chromosomal gene clusters usually contain 15-conserved open reading frames (ORFs) and are present in most of the sequenced marine alpha-proteobacteria genomes. Some marine strains have been shown to produce GTA particles that were biologically active in marine environment.

GTA particles range in size, morphology and the amount of host DNA they package. To date, the characteristics of GTAs are largely based on observations of …

Measuring Up: Standardized Testing And The Making Of Postwar American Identities, 1940-2001, Keegan J. Shepherd

USF Tampa Graduate Theses and Dissertations

Standardized testing is a defining feature of contemporary American society. It not only governs how people are channeled through their schooling; it amplifies existing social disparities. Nonetheless, standardized testing endures, namely because it has served as a vital tool for the post-1945 American state. The postwar state prioritized, on the one hand, the cultivation of intellects resilient enough to sustain American geopolitical supremacy through scientific discovery and technological innovation and, on the other hand, the maintenance of an obedient population that would not disrupt existing social hierarchies. Standardized testing helped the postwar state solve this mind-body dilemma. As a function …

Cell Division Regulation In Staphylococcus Aureus, Catherine M. Spanoudis

USF Tampa Graduate Theses and Dissertations

Cell division is a fundamental biological process that occurs in all kingdoms of life. Our understanding of cell division in bacteria stems from studies in the rod-shaped model organisms: Gram-negative Escherichia coli and Gram-positive Bacillus subtilis. The molecular underpinnings of cell division regulation in non-rod-shaped bacteria remain to be studied in detail. Rod-shaped bacteria possess many positive and negative regulatory proteins that are essential to the proper placement of the division septa and ultimately the production of two identical daughter cells, many of which are absent in cocci. Given that essential cell division proteins are attractive antibacterial drug targets, it …

The Fate Of Fecal Indicator Bacteria In Passive Nitrogen Reduction Systems, Michelle B. Henderson

USF Tampa Graduate Theses and Dissertations

The sustainability of water resources is an international and national concern. With increased human activity, water distribution on a global, regional, and local scale has been negatively impacted. Managing water resources also includes managing wastewater. A promising solution to the issues of water scarcity and distribution in the environment is the reuse of wastewater. Wastewater is produced from various sources (domestic, industrial, and commercial); however, if this water is able to be reused closer to the source of generation it could positively impact water distribution. In the United States, approximately 25% of domestic wastewater is treated in onsite wastewater treatment …

The Effects Of Loneliness On Consumers’ Digital Engagement With Social Media Ads, Yu Qin
