| Summary: | Thesis advisor: Heather C. Olins === This study creates a protocol to investigate microplastics in local freshwater wetlands surrounding Boston College. This study also investigated potential plastic-degrading bacteria in the sediment of local freshwater wetlands. A list of potential plastic-degrading bacterial species and genera were compiled from the literature. Using these compiled lists, we searched for these potential plastic-degrading organisms in our metagenomics and 16S datasets. Looking for potential correlations between abiotic factors and the abundance of potential plastic-degrading bacteria, for both data sets, it was found that sandy sediment had a higher abundance of potential plastic-degrading bacteria than non-sandy sediment. Finally, our list of plastic-degrading bacterial species was cross-referenced with a previously compiled list of potential pathogens. Of the 26 taxa in our sites that were identified as potential plastic-degrading bacteria, 57.69% of those taxa are also potentially pathogenic to humans. === Thesis (BS) — Boston College, 2020. === Submitted to: Boston College.
