Abstract

Degradation with an aerobic consortium was used to evaluate the bioremediation trichloroethylene (TCE) as a model substrate. After one week, 228-1186 mg TCE l^-1 was degraded at rates of 20-50 μg TCE l ^-1 h^-1. The introduction of 10 mg toluene l^-1 enhanced the degradation rates for TCE when greater than 600 mg l^-1. Using isolated enzymes, a TCE degradation intermediate(s) appears inhibitory to the oxygenase enzymes thereby diminishing the overall degradation.
