C.E.R.E.S. Petroleum Hydrocarbon Treatment Bacteria for Petroleum Remediation

Engineered Bacteria for Enhanced Bioremediation of Petroleum Hydrocarbons, Fuels, and Oils.

Petroleum Treatment Bacteria (PTBac) contains a blend of facultative hydrocarbon degrading bacteria specifically chosen for the petrochemical industries applicable to both aerobic and anaerobic conditions. This product provides a significant boost to biodegradation rates when combined with PTS to rapidly achieve treatment goals and reduce the overall costs of remediation. Bioaugmentation with PTBac and PTS is recommended when treatment goals require accelerated rates of biodegradation of petroleum hydrocarbons, fuel oxygenates, polyaromatic hydrocarbons, chlorinated benzene and other petroleum remediation applications in soil, groundwater, and surface water environments.

For Bioremediation Applications

PTBac was designed to augment native bacteria to accelerate biological degradation processes of petroleum hydrocarbons and improve proliferation of biodegrading bacteria for soil and groundwater remediation. Bioremediation is often performed in conjunction with mechanical remediation systems such as SVE, DPE, MPE and Air Sparge because those systems help introduce oxygen to support oxidation demands of bacteria. For In-situ applications and older releases, the bacteria require the nutrients provided in PTS to increase the rate of biodegradation resulting in faster cleanup.

In the case of surface spills of oil and refined fuels on land, in rivers or spills in the ocean, PTBac works in conjunction with PTS Advanced which solubilizes the pure phase gasoline, diesel and other petroleum hydrocarbon fuels and long chain hydrocarbons and promotes biodegradation. It is safe to aquatic ecosystems, humans, and other living organisms and is actually ideal for sustainable rejuvenation of soil for reuse in the environment. Contact us to learn more about our variations of PTS for your site specific challenges.
