Diverse Community Of Arsenic Resistant Bacteria Display Arsenate Reducing Capabilities, Stephanie Maeda
Undergraduate Honors Theses
Naturally found in soil and water environments arsenic is toxic to many organisms, carcinogenic to humans, and poses a significant public health risk. Yet communities of bacteria found thriving in arsenic ridden environments have evolved mechanisms to tolerate and exploit both oxidation states of this heavy metal (arsenite and arsenate). As the site of an old arsenic mine, Black Mountain Open Space Park in San Diego, California has yielded concentrations of arsenic in the soil between 111-14,800 ppm. Exceeding average arsenic soil concentrations and levels considered safe in the environment by the World Health Organization, we sought to characterize the …

Analysis Of Bacterial Dna And Water Quality: Surface Water Sampling At Gardner-Webb University, Celsea Reeder
Undergraduate Honors Theses
Part 1 of this experiment was to explore the bacterial types within the surface water on the campus of Gardner-Webb University, located in Boiling Springs, NC. Two water samples were collected from four locations on campus, including the boiling spring, Lake Hollifield, and an adjacent creek. Using the Zymo Research “Quick-DNA™ Fungal/Bacterial Miniprep Kit,” the bacterial DNA within these samples was isolated and sent to Psomagen, Inc. for analysis. The resulting DNA sequences were analyzed through BLAST, and subsequently interpreted. For the second part of this experiment, one surface water sample was taken from the boiling spring, and another …
