The organisms that degrade MtBE under anaerobic conditions are evolved to acquire energy for growth by using molecular hydrogen and carbonate ion to cleave methyl ether bonds.

Methyl ether bonds are common in nature and the bond also occurs in MTBE. MTBE in contaminated ground water will be degraded under anaerobic conditions if adequate concentrations of molecular hydrogen are available, usually from the methane fermentation of BTEX compounds.

Anaerobic biodegradation of MtBE produces strong fractionation of stable carbon isotopes. This...
