Petrox microbe thrive on naphthalene and are very efficient at naphthalene bioremediation in the field. In fact, naphthalene is occasionally used in the QA/QC process to verify Petrox viability and effectiveness. In this test, the Petrox organisms are placed on an agar devoid of a carbon source. The naphthalene is applied to the top plate as the sole carbon source. The Petrox viability is then demonstrated by colony growth on the top plate as shown on the following picture.
Cl-Out bioremediation reduced high concentrations of TCE and daughter compounds in ground water at an industrial site near Newark, New Jersey to meet an aggressive redevelopment schedule. Using a dynamic remediation plan, three applications of CL-Out microbes followed remediation progress sampling during the site preparation for construction. After reducing the maximum CVOC concentrations from over 8,000 ug/L to less than 20 ug/L, the site met the remediation goals and received a No Further Action Letter from NJDEP.

CL-Out® was successfully used to remediate solvents in ground water at an operating industrial site in central New Jersey. The the facility was a manufacturing and plating company with historical petroleum and solvent releases.
Chlorinated solvents were found in the ground water in two plumes covering a combined area of about one half acre. The contaminants were a mix of chlorinated solvents including 1,1,1-TCA, 1,1-DCE and PCE in low concentrations. The remediation goal was to reduce the mass of contamination in the ground water plume to prevent mitigate off-site risks.
After the CL-Out application, ground water concentrations in all monitoring wells decreased by more than 80%, which was sufficient to meet the remediation standards. Click here to download a complete case study.
Petrox reduced the concentration of TPH in soil at a former gas station from 9,500 mg/kg to 52 mg/kg. The impacted soil was at more than 20 feet deep. Injection of calcium peroxide provided the oxygen needed for metabolism of the petroleum by Petrox microbes. The post treatment sampling was 90 days after the bioaugmentation, so that even though the average remediation rate was 105 mg/kg/day, the peak remediation rate must have been much higher when the Petrox population was higher.
This is another example of fast, reliable bioremediation by Petrox organisms.
CL-Out bioremediation of chlorinated solvents like PCE and TCE is an aerobic cometabolic process. As these compounds are not directly metabolized under aerobic conditions, the competitive advantage goes to the CL-Out organisms that cometabolize them. While utilizing a sugar substrate, the CL-Out organisms produce enzymes mono- and dioxygenase that bridge the carbon bond to destabilize the compound. The solvent is converted to an organic acid that the organism can metabolize. The benefit is that CL-Out bioremediation can be applied to soils both in situ and ex situ.
