Objective:

In the last two decades, methyl tertiary-butyl ether (MTBE) gained widespread use as an octane enhancer and fuel oxygenate in gasoline and also has become a frequently detected and problematic ground and surface water contaminant. One desirable fate process for oxygenated gasoline in contaminated environments is microbial biodegradation. The objective of this research project was to conduct a series of laboratory studies to conclusively demonstrate the susceptibility of MTBE, and its known metabolite tertiary-butyl alcohol (TBA), to anaerobic biodegradation by inocula from gasoline-contaminated aquifers where BP field monitoring suggests that this is occurring. Ultimately, demonstrating the anaerobic biodegradation of MTBE and understanding the process will help buttress claims for the intrinsic bioremediation of this gasoline-additive in contaminated aquifers.
