Biodegradation Of Highly Weathered Deepwater Horizon Oil, Joel T. Bostic
Theses and Dissertations
Oil from the Deepwater Horizon (DwH) spill continues to be found on beaches five years post-spill. Understanding the role of microbes in removing DwH oil from sandy beaches is necessary to elucidate the fate of DwH oil in the coastal zone. Oiled sand patties and non-oiled sand were collected from affected beaches five years post- DwH. Biomarkers in oiled sand indicated that sand patties originated from the DwH spill, however the oil was heavily weathered and dominated by oxygenated hydrocarbons. Microbial communities, as measured by phospholipid fatty acids (PLFA), were present on oiled sand patties and distinct from microbes on …
