Monitoring biodegradation of methyl tert-butyl ether (MTBE) using compound-specific carbon isotope anaysis

Article Abstract:

The potential of compound-specific isotope analysis to assess in situ biodegradation of methyl tert-butyl ether (MTBE) in groundwater is examined in laboratory studies at the University of Waterloo, Waterloo, Ontario, Canada. The research suggests that carbon isotope analysis could possibly be used to trace in situ biodegradation of MTBE and tert-butyl ether.

Potential aerobic MTBE biodegradation

Article Abstract:

United States Geological Survey scientists have sampled 11 stream and lake bed sentiment sites for methyl tert-butyl ether, a gasoline additive. The study indicates that methyl tert-butyl ether is biodegradable, but that further study is needed to know to what extent. A map showing sample sites is included.

Hydrogen and carbon isotope fractionation during aerobic biodegradation of benzene

Article Abstract:

Benzene from several manufacturers is biodegraded in laboratory experiments with Acinetobacter sp. and Burkholderia sp. and evaluated for hydrogen and carbon isotope fractionation. Differences in isotopes between the types of benzene are graphed and the use of isotope analyses is suggested as a method to trace biodegradation of benzene and distinguish different sources of contamination.
