Quantifying The Role Of Water Quality On Nitrogen Cycling In A Trophic Estuary, Kayla Gonzalez-Boy

Symposium of Student Scholars

Jobos Bay Estuary is an intertidal, tropical estuary located in southern Puerto Rico. The estuary covers about 12 km² and has a variety of habitats, such as seagrass beds, mangroves, mud flats, and coral reefs, which play important roles in sediment trapping and water quality maintenance. Seagrasses also serve as nursery and feeding grounds and provide shelter for macrofauna. Currently, the role of seagrasses and water quality on nitrogen (N) cycling in trophic estuaries is not well constrained. Understanding variations in sediment-based effects on N cycling rates and transformations, and how they are associated with water quality, is an …

Investigating The Activity Of Alternative Warheads For Targeted Covalent Inhibition Of The Inhibitor Vertebrate Lysozyme Protein From Pseudomonas Aeruginosa, Katie Hambrick

Master of Science in Chemical Sciences Theses

Pseudomonas aeruginosa (P. aeruginosa) is a Gram-negative bacterium that causes blood and lung infections in hospital environments due to its ability to survive on improperly sterilized medical equipment. P. aeruginosa has developed several multi-drug resistance mechanisms that make it very difficult to treat with current antibiotics.¹ This presents the need for a new class of antibiotics that cannot be overcome by P. aeruginosa’s mechanisms of resistance.

The primary goal of this project was to develop a small library of inhibitors that could later be incorporated into lead compounds for novel antibiotic drug discovery. One of P. …
