WebDescription. Cometabolic bioremediation occurs when an enzyme or cofactor, produced by a microbe to catalyze the degradation of its metabolic substrate, is also capable of degrading target compounds. Cometabolic bioremediation is designed to target contaminants of concern (COCs) by stimulating or augmenting this biological process. Webdechlorination of tetrachloroethene (PCE) or trichloroethene (TCE) can result inthe accumulation of lesserchlorinated compounds such as cis-1,2-dichloroethene (cDCE) or ...
