Biodegradation of trichloroethylene (TCE) under aerobic conditions
The industrial solvent trichloroethylene (TCE) is among the most ubiquitous chlorinated compound found in contaminated groundwater. The objective of this study was to examine the feasibility of TCE biodegradation using glucose as the primary substrate and using TCE as a sole substrate under aerobic condition. Microcosms inoculated with acclimated activated sludge were constructed. Results indicate that glucose can serve as a primary substrate and enhance TCE biodegradation under aerobic cometabolism; the TCE first order biodegradation rate at 25℃ was 0.321 day-1. Also, results indicate that TCE can serve as a sole substrate and be biodegraded under aerobic conditions; the TCE first order degradation rate at 25℃ was determined to be 0.262 day-l. No intermediate degradation products such as dichloroethene and vinyl chloride were detected during the experiments.
