Bioremediation of tce
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. WebApr 1, 2016 · Remediation of TCE-contaminated sites is not an easy task because of the complex distribution of TCE throughout the subsurface. Bioremediation has been applied as a remedial strategy to clean up TCE-contaminated aquifers. In situ reductive dechlorination of TCE operates under anaerobic conditions, which results in the …
