Trends in engineered bioremediation indicate that the treatment of chlorinated solvent contamination can, under circumstances, result in the slow biodegradation of intermediate compounds. When faced with this problem, bioaugmentation with a microbial consortium such as Bio-Dechlor INOCULUM® Plus offers a solution to accelerate the complete dechlorination of these otherwise recalcitrant contaminants.
Bio-Dechlor INOCULUM Plus (BDI Plus) is designed for use at sites where chlorinated contaminants are present and unable to be completely biodegraded via the existing microbial communities. BDI Plus is an enriched, natural microbial consortium containing species of Dehalococcoides sp. (DHC) which are capable of completely dechlorinating contaminants during in situ anaerobic bioremediation processes. BDI Plus has been shown to stimulate the rapid dechlorination of chlorinated compounds such as tetrachloroethene (PCE), trichloroethene (TCE), dichloroethene (DCE), and vinyl chloride (VC). It also contains microbes capable of dehalogenating halomethanes (e.g. carbon tetrachloride and chloroform) and haloethanes (e.g. 1,1,1 TCA and 1,1, DCA) as well as mixtures of these halogenated contaminants.
BDI Plus can be used at most any stage of a project to ensure the rapid and complete degradation of chlorinated compounds. Specifically, Bio-Dechlor INOCULUM Plus can be added to an aquifer at the beginning of a project in situations where there is a lack of, or suboptimal populations of Dehalococcoides sp.
BDI Plus is provided in a liquid form which is directly injected into the contaminated subsurface either with or following a staged-release electron donor (food source) application. Once in place, this microbial consortium accelerates the extant rate of chlorinated contaminant degradation from parent compounds to intermediates (like dichloroethene (DCE) and vinyl chloride (VC)) and completely through to harmless end products such as ethene and ethane.
BDI Plus is compatible with most electron donors however it is recommended that remediation practitioners use a staged-release technology like 3-D Microemulsion® or Hydrogen Release Compound (HRC®) for optimal performance and longevity.
