Hydrocarbon Organic Treatment

All of our MicroChoice ® specialty ingredients are available in customizable formulations for your company to use in combination with other ingredients into your own unique final product.

MicroChoice ® HCT

A concentrated, dry blend of stabilized bacterial spores and micronutrients formulated for use in the degradation of petroleum-based hydrocarbons.

Refinery wastewater contains petroleum hydrocarbons and non-petroleum organic wastes. For this reason, MicroChoice® HCT contains a synergistic blend of petroleum degrading and organic waste degrading bacterial strains.

Each strain in MicroChoice® HCT was selected to work under diverse environmental conditions and provide the most complete digestion of petroleum and petroleum degradation by-products.

MicroChoice® HCT contains proven petroleum degrading strains. As shown in the two graphs on the right, gas chromatograph analysis confirmed that these strains metabolize hydrocarbon products such as gasoline, oil, diesel, and BTEX (Benzene, Toluene, Ethylbenzene, and Xylene).

The bacterial cultures in this blend are also beneficial in treating soil tainted with hydrocarbons.  Soil treatments can be spray applied or tilled into the contaminated soil.  The addition of nutrients in soil applications to balance the system often shows increased activity.
