Biological reductive dechlorination
WebReductive dechlorination by cometabolism is the reduction of a chlorinated organic compound by an enzyme or co-factor produced during the metabolism or another substrate. Since the contaminant reduction reaction doesn’t directly benefit microorganisms, a primary substrate must be present in the environment as a carbon and energy source.
