Bioaugmentation
Culturing & Sales

BTC has the following commercially available bioaugmentation cultures:

NJ-14 Mixed Culture
Degrades PCE, TCE, 1,2 DCE, VC to ethene; also degrades 1,1 DCE, 1,2 DCA; degrades 1,1,1 TCA, 1,1 DCA to chloroethane (CA) and ethane sulfides. This is the most robust, commercially available culture in the USA- can degrade hundreds of mg/L of TCE/PCE and up to 50 mg/L of 1,1,1 TCA. We expect that with acclimation, higher TCA concentrations can be degraded. BEWARE that most other commercially available bioaugmentation cultures (such as KB-1) can not degrade TCA and are chloroform intolerant (Water Research 36:4193).

BTC is the only firm authorized (by the site owner) to grow and sell the NJ-14 dehalococcoides ethenogenes (DE) mixed culture. The NJ-14 mixed culture is the most robust commercially available DE culture, having its origins from a site contaminated with almost every VOC on the 8260 list at concentrations in the thousands of ppm! The NJ-14 mixed culture is 1,1,1 TCA resistant and can degrade hundreds of mg/L of PCE and TCA series compounds. Our NJ-14 mixed culture is also capable of dechlorinating PCE and TCA in the presence of up to 7 mg/L of chloroform.

BW-05 MTBE Culture
Our BW-05 culture can aerobically degrade MTBE as the sole carbon source. The culture can be added in-situ to the area of air sparging or can be seeded to an above ground reactor/vessel such as GAC (must be pressure rated) to minimize GAC consumption and maximize MTBE degradation.

SL-D Culture
Propanotroph that degrades 1,4 Dioxane, TCE, 1,1,1 TCA, DCA, DCE , VC to carbon dioxide. BTC is also the only firm authorized (by the site owner) for the SL-D propanotroph culture that can degrade tens of mg/L of 1,4 Dioxane (plus TCE, TCA) within hours in the presence of low concentrations of dissolved propane and oxygen.

Custom Cultures
BTC grows its cultures in YOUR site water and this process requires up to 120 days. As such, the bioaugmentation culture will work at your site water and will not be inhibited by factors such as conductivity and site specific contaminants, metals concentrations etc.

Sale Restrictions
Our cultures are not available to all potential buyers. Culture sales are approved on a case by case basis when BTC (and other culture stake-holders) believes the culture will be properly applied and that the remediation will be properly conducted. Our interest is that our cultures never fail in the field and we prefer to not make a sale rather than to taint our current 100% success rating.
