    The release of crude oil during leaks and spills introduces organic contaminants to the environment. Using microbial fuel cells (MFCs) as a bioremediation alternative can increase contaminant degradation rates while providing a way to monitor biodegradation in situ. The objective of this study is to use an MFC to compare power generation and biodegradation in 2 different sediment types: an historically oil-contaminated wetland sediment and an oil-spiked river sediment not previously contaminated. Voltage measurements were taken with a multimeter to produce polarization and density curves to help determine useful current parameters for maximum power production. Samples of the sediment were preserved for chemical and microbial community analysis. After 7 days, a maximum power of 1.1 mW/m2 (normalized to cathode area) was produced by the wetland sediment as compared to a maximum of 0.0281 mW/m2 for the river sediment. Preliminary results for these systems indicate the effects of sediment type and microbial community on power production and biodegradation potential.
