Bioaugmentation

BAC-9™

Bioaugmentation is the addition of natural microbial strains or laboratory enriched variants to the environment to enhance bioremediation.  This can be a highly productive cleaning resource.

EOS Remediation introduces BAC-9™ – an enriched bioaugmentation culture capable of degrading chlorinated solvents to innocuous compounds efficiently via halorespiration. 

BAC-9™ is superior in bioaugmentation for the treatment of chlorinated ethenes. Time can often be a significant factor and expense for in situ bioremediation projects.  By adding BAC-9™ at the beginning, projects receive a "jump start" from the microbial community, reducing the time required to grow the Dehalococcoides sp. population to effective cell densities. 

Types of Application

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

When Does BAC-9™ Make Sense?

• Accelerated site closeout
• Inadequate microbial activity
• Incomplete dechlorination following biostimulation

Simply Better

• Degrades chlorinated solvents: tertachloroethene (PCE), trichloroethene (TCE), cis-1,2-dichloroethene (cis-DCE), vinyl chloride (VC), trichloroethane (TCA), carbon tetrachloride (CT), chloroform (CF)
• Rapid and complete degradation of cis-DCE and VC
• Degrades high concentrations of contaminants

Custom Enrichments

If indigenous Dehalococcoides strains are at low population densities, EOS Remediation also has resources to develop custom enrichments from contaminated site groundwater for bioaugmentation. 

Based on your needs, custom enrichments can be produced in fermentors ranging from 7 to 4000 liters per batch, for even the largest contaminated sites. The achievement of appropriate Dehalococcoides sp. cell density is monitored using real-time qPCR.
