BAC-9™

Accelerating the Effectiveness of Biostimulation

 

 

EOS Remediation offers BAC-9TM - an enriched bioaugmentation culture capable of degrading chlorinated solvents to innocuous compounds efficiently via halorespiration. Time can often be a significant factor and expense for in situ bioremediation projects.  By initial addition of BAC-9TM at a project site, the contaminated area receives a "jump start" from the microbial community, reducing the time required to grow the Dehalococcoides . population to effective cell densities.sp

Types of Application

  • Direct injection for in situ treatment of chlorinated ethenes.
  • Inoculation of on-site bioreactors.

Best Conditions for Use

  • Accelerated site closeout preference.
  • Inadequate native dechlorinator population density.

 Application Results

  • Rapidly and completely degrades cis-1,2-dichloroethene (cis-DCE) and vinyl chloride (VC).
  • Effective on many other chlorinated solvents: tetrachloroethene (PCE), trichloroethene, (TCE), trichloroethane (TCA), carbon tetrachloride (CT), chloroform (CF).
  • Resistant to and effectively reduces high contaminant concentrations.

Custom Enrichments

If indigenous Dehalococcoides group organisms are at low population densities, EOS Remediation has resources to develop enrichments from site groundwater for use during bioaugmentation.  Based on your site requirements, custom indigenous enrichments can be produced in fermentors ranging from 7 to 4000 liters per batch. Dehalococcoides sp. cell density is monitored using real-time quantitative polymerase chain reaction (PCR).
