Polycyclic Aromatic Hydrocarbons And The Microbiomes Of Two Benthic Species, Samantha Ells

Master's Theses

The presence of oil has been shown to affect the microbiomes of the water column, sediments, and organisms, both by altering the diversity and the composition of those microbial communities. If the microbiome is altered it may no longer provide benefits to its host organism, impacting its ability to survive. Thus, it is important to understand the effects of large-scale contamination events including the Deepwater Horizon oil spill. This study set out to examine the effects of oil exposure on the microbiome of two benthic species, southern flounder (Paralichthys lethostigma) and eastern oysters (Crassostrea virginica) to further understand the effects …

Microbial Community Response To Light And Heavy Crude Oil In Freshwater Systems, Timothy M. Butler

Dissertations, Master's Theses and Master's Reports

With increased demand for oil, there is an increased risk for oil spills in many environments. A number of pipelines transport oil near or across freshwater systems including the Great Lakes. Microbes are capable of breaking down oil and have thus been proposed as tools for oil spill response through bioremediation. There is a need to understand the microbial response to diverse oil types in freshwater environments due to the lack of research into this topic. This study’s main objectives are to understand how the freshwater microbial communities respond to oil, and how the bacterial communities may respond to different …

Pcr Primers For The Detection Of Propane And Butane-Oxidizing Microorganisms, Brian Jeremy Chan

Master's Theses

In an increasingly energy-hungry world, our capacity to meet the heightened energy demands of the future has become a pressing matter. The most urgent of these concerns are tied to the accessibility of petroleum. Various experts have proselytized both the imminent arrival of peak oil production rates and the ensuing decline of those rates thereafter. And to that end, the development of novel and advanced oil exploration methodologies has become almost as important as finding the sources of oil themselves.

The soils above petroleum reservoirs play host to various communities of alkane- oxidizing bacteria that can utilize the natural gas …
