Widespread potential for microbial MTBE degradation in surface-water sediments

Article Abstract:

The microorganisms collected from 11 stream and lake bed sediments in the United States. showed significant mineralization of methyl-tert-butyl ether (MTBE), indicating that aerobic bed sediment microbial processes may provide an environmental sink for MTBE in surface water systems and may help in the transience of MTBE in some surface waters.

Methyl tert-butyl ether biodegradation by indigenous aquifer microorganisms under natural and artificial oxic conditions

Article Abstract:

Methyl tert-butyl ether(MTBE) is a gasoline additive used for octane enhancement in the United States, which results in lower emissions of ozone and carbon monoxide precursor compounds, and it thought to have potentially dangerous health risks associated with it. Research of the amount of MTBE transported by groundwater flow shows that MTBE can quickly mineralize to carbon dioxide under artificial and natural oxic conditions.

Effect of contaminant concentration on aerobic microbial mineralization of DCE and VC in stream-bed sediments

Article Abstract:

Intrinsic bioremediation appears to be an effective method in decontaminating highly-polluted aquifer systems. Results revealed that bed-sediment microorganisms indigenous to a creek have rapidly mineralized vinyl chloride (VC) and dichloroethene (DCE) under aerobic conditions. The rates of DCE and VC mineralization, however, depends on contaminant concentration.
