Degradation of chlorinated aliphatic compounds by methane and phenol-oxidizing bacteria
- Univ. of Washington, Seattle, WA (United States)
Chlorinated aliphatic compounds (CACs), such as trichloroethylene (TCE), cis-1,2-dichloroethylene (c-DCE), chloroform (CF), and 1,1,1-trichloroethane (TCA), are common groundwater contaminants. Aerobic cometabolic degradation of these compounds has been fortuitously accomplished by nonspecific oxygenase enzymes produced by methane, phenol, propane, and ammonia-oxidizing bacteria. The reaction also requires nicotinamide adenine dinucleotide (NADH) and oxygen. This paper compares the ability of methanotrophic and phenol-oxidizing enrichments to degrade chlorinated aliphatic compounds, with a focus on the important application issues of degradation rates, competitive inhibition, and intermediate toxicity. Bioremediation implications are discussed.
