CL -Petrox

Petrox™ delivers active, rapid bioremediation of environmental contamination caused by industrial and commercial hydrocarbons.

Petrox HRAn All-Natural Product

It contains a highly-concentrated solution of live, strains of lyophilized (freeze-dried) Pseudomonas organisms that occur naturally in the earth’s ecosystem. These cultures are free of pathogens and there is no artificial mutation or genetic engineering involved. Extracted from a once-contaminated site and isolated under controlled laboratory conditions, these “hungry bacteria®” have only one purpose in life: to seek and destroy petroleum hydrocarbons, organic solvents, and semi-volatile hydrocarbons at their source, and then quickly convert them into harmless, naturally recyclable by-products.

From Brown To Green Faster

Site closure often occurs in a matter of weeks or months versus several years or more for other methods, giving users the combined benefit of fast site closure and remarkable cost savings.

Standard Blends

Available in three standard blends or custom formulated for specific needs, Petrox can be used as a highly effective stand-alone decontamination solution or as a powerful augmentation to speed the remediation of existing treatment systems.

Petrox 1™- BTEX compounds (Benzene, Toluene, Ethylbenzene, Xylene), Dichlorotoluene (2,5-), Dioctylphthalate (common plasticizer), Fuels (gasoline, diesel and heating oils), Methyl Ethyl Ketone (MEK, 2-butanone), Methylene Chloride, Mineral spirits, Naphthalene, Stoddard solvents, Polycyclic Aromatic Hydrocarbons (PAHs), and trimethylbenzene isomers.

Petrox 2™- Citrus Industry by-products, D-Limonene (Including citrus-based cleaning compounds), Isoprenoids (A class of organic compounds produced by plants), Terpene compounds (Natural hydrocarbons produced by plants), and Terpene-based solvents.

Petrox 3™- Anthracene, Chlorotoluene (M-), Chlorotoluene (O-), Chlorotoluene (P-), Chrysene, Cresols, Creosote, Fluorene, Oils and Greases (Food and petroleum), Pesticides, including 1,2-D, 2,4-D, Aldrin, Endrin, Pentachlorophenol (PCP), Phenanthrene, and Phenol.


  • Commonly used at fuel terminals and gas stations, in the metals and chemicals industries, citrus production, railroads, manufactured gas plants, and wood treatment facilities.
  • Designed for stand-alone application or for augmentation of existing treatments, including vapor stripping, sparging, excavation, and dual-phase extractions technologies.

Each Petrox product batch is manufactured under sterile conditions, and subjected to stringent quality control protocols before release for shipment. Available as a freeze-dried powder and hydrated on site for the highest possible microbial activity, each culture is provided with unique nutrient/growth factor formulation to maximize viable cell count.
