AEROBIC - OXIDATIVE
Aerobic bioremediation (oxidative bioremediation) is more than just simply adding oxygen or a certain species of bacteria. Successful bioremediation efforts must incorporate all of the necessary components: an abundant supply of electron acceptors, nutrients for building cell mass, active cultures to spur on microbial growth, and enzyme enhancements to increase bioavailabilty.
Bioremediation products must be easy to apply, which is why our products are designed to be 100% soluble.

PetroBac™ Stimulant Bundle includes our flagship TPH Bacterial Consortium (EZT-A2™) and Enzyme Accelerator (EZT-EA™).
Proven again and again on thousands of sites, PetroBac™ completely mineralizes contaminants to CO2 and H2O with no by-products!
PETROBAC™ STIMULANT BUNDLE
PetroBac™ is your answer for low-cost hydrocarbon cleanup using robust, adaptable bioremediation Recommended for all active petroleum related bioremediation projects to maximize contact between the contaminants (dissolved and adsorbed) and the bacteria. Bioremediation is a contact technology – the bacteria must physically contact the hydrocarbon food source, and the electron acceptors (oxygen, nitrate, sulfate) to biochemically oxidize the contaminants.
EZT-EA™: ENZYME ACCELERATOR
EA™ is a rhamnolipid based biological enhancement designed to mimic extra-cellular enzymes. EA™ improves the efficiency of both enzymes and bacteria by enhancing hydrolysis, or the “coming together” of the water-based biological enhancements with oil-based contaminants. In other word EA™ makes contaminants more bio-available for bacteria. EA™ is recommended for most enzyme and bacterial applications.
EZT-A2™: TPH BACTERIAL CONSORTIUM
A2™ is a biological consortium for the destruction of petroleum hydrocarbons. A2™ supplies of a large population of pre-acclimated bacteria to optimize initial growth of a healthy, in-situ, hydrocarbon-degrading microbial population. Continuous addition via recirculation ensures populations stay elevated through out the remediation project. We recommend A2™ for all active hydrocarbon related bioremediation projects.
While EA™ and A2™ are available separately, these products were designed to complement each other for complete, rapid remediation.
CUSTOM BLEND NUTRIENTS FOR BIOREMEDIATION
Typically combined with our PetroBac™ bundle, CBN™ is a nutrient amendment designed specifically for enhanced attenuation and bioremediation of petroleum hydrocarbon constituents (gas, BTEX, diesel, oil) in soil and groundwater. It contains a balanced blend of macro-nutrients (nitrogen, phosphorus, and potassium), micro-nutrients, and secondary electron acceptors (nitrate and sulfate) that bacteria need to thrive.
CBN™ contains the essential building blocks that all bacteria need in order to produce new cell mass and perform cellular functions. Biological processes utilize nutrients according to a Carbon: Nitrogen: Phosphorus (C:N:P) ratio minimum of 100:20:5. Therefore, in order to degrade 1,000 lbs. of TPH, a minimum of 200 lbs. of Nitrogen and 50 lbs. of Phosphorus will be required by the microbial population. These masses of nutrients are not naturally available in most groundwater systems, and must be supplied externally during active bioremediation in order to ensure uninhibited contaminant degradation.
CBN™ is fully soluble in water, with no measurable viscosity and a maximum solubility of approx. 1 lb. per gallon of water. The mixing ratio can be adjusted depending upon the application method. Appropriate ongoing nutrient addition should be determined by soil/GW sampling for ammonia, nitrate, and orthophosphate.
