Detecting Potentially Neurotoxic Pseudo-Nitzschia Species In The Grand Strand Area, Chesney Price
Detecting Potentially Neurotoxic Pseudo-Nitzschia Species In The Grand Strand Area, Chesney Price
Honors Theses
Pseudo-nitzschia is a globally distributed diatom genus which contains 26 neurotoxin (domoic-acid) producing species. In shallow coastal waters these diatoms are associated with both the development of harmful algal blooms and the bio-accumulation of toxins in shellfish that can impact human health. Pilot data recovered in 2018 indicated the presence of multiple species of Pseudo-nitzschia, including domoic-acid producing taxa. We hypothesize that we will recover a similar species diversity using multiple sampling dates during the summer of 2021. Environmental DNA (eDNA) samples taken from the public shellfish harvesting area waters at Huntington Beach State Park (SC) over a two month …
Composting During Winter Versus Summer: A Microbial Analysis, Madison Ochs
Composting During Winter Versus Summer: A Microbial Analysis, Madison Ochs
Honors Theses
Pre-consumer food waste, hay, and woodchips were composted using two different methods of static composting: forced aeration (FA) and natural aeration (NA). The composting process was performed during the winter and summer for 106 and 124 days, respectively. The composting process for both winter and summer processes did not reach the temperature above the 40°C threshold of the thermophilic stage in composting. The microbial communities present during different timepoints (start, peak, and final) along the composting process were analyzed with DNA sequencing techniques and visualized using QIIME 2, an open-source bioinformatics platform. The microbial communities of the winter and summer …
