Methyl tert-butyl ether (MTBE) bioremediation studies
The massive production of methyl tert-butyl ether (MTBE), a primary constituent of reformulated gasoline, combined with its mobility, persistence and toxicity, makes it an important pollutant. It was considered recalcitrant until a few years ago, but recently MTBE biodegradation in aerobic conditions has been demonstrated with both mixed and pure cultures. Mixed cultures are generally the more ...
متن کاملUsing Vegetation to Treat Methyl- Tert-butyl Ether Contaminated Groundwater
Methyl-tert-butyl ether (MTBE) is a commonly used gasoline additive. Leaking underground storage tank systems, spills, and pipeline failures are the causes of reported groundwater contamination with MTBE. The impact of vegetation on MTBE plume transport in groundwater and volatilization was experimentally examined. The experimental system consists of six channels, five of which are planted with...
متن کاملNaturally occurring bacteria similar to the methyl tert-butyl ether (MTBE)-degrading strain PM1 are present in MTBE-contaminated groundwater.
Methyl tert-butyl ether (MTBE) is a widespread groundwater contaminant that does not respond well to conventional treatment technologies. Growing evidence indicates that microbial communities indigenous to groundwater can degrade MTBE under aerobic and anaerobic conditions. Although pure cultures of microorganisms able to degrade or cometabolize MTBE have been reported, to date the specific org...
متن کاملCometabolism of methyl tert-butyl ether (MTBE) with alkanes
The release of methyl tert-butyl ether (MTBE) to the environment, mainly from damaged gasoline underground storage tanks or distribution systems spills, has provoked extended groundwater pollution. Biological treatments are, in general, a good alternative for bioremediation of polluted sites; however, MTBE elimination from environment has constituted a challenge because of its chemical structur...
متن کاملImpacts of Ethanol on Anaerobic Production of Tert-Butyl Alcohol (TBA) from Methyl Tert-Butyl Ether (MTBE) in Groundwater
Methyl tert-butyl ether (MTBE) is a contaminant of concern to groundwater resources due to its persistence in subsurface environments. MTBE appears to be degraded readily in the presence of oxygen but is recalcitrant under the anaerobic conditions prevalent in the subsurface, and can be converted into the more toxic compound tert-butanol (TBA). As ethanol is being promoted as a renewable fuel a...
