We look forward to helping you develop the optimally cost-effective, remediation approach.
Under anaerobic conditions, organic contaminants can serve as the electron donors or electron acceptors during biodegradation processes (USEPA, 2013).
Electron Donors for Anaerobic Reductive Bioremediation
Anaerobic reductive bioremediation is the practice of adding biologically available organic bioremediation amendments, referred to as organic substrates or electron donors, to groundwater to generate and sustain anoxic conditions by consuming oxygen via aerobic respiration, as well as other electron acceptors, during its biodegradation. By generating hydrogen through fermentation reactions, it promotes the bioreduction of oxidized contaminants such as chlorinated solvents. The chlorinated compounds serve as electron acceptors and undergo reductive dechlorination under anaerobic conditions in the presence of an electron donor (USEPA, 2013). Tersus bioremediation amendments are formulated to optimize in situ remediation of contaminated soil and groundwater. We provide:
- Emulsified Vegetable Oils (EVO): NanoEVO™ and EDS-ER™
- EVO Emulsifiers: TASK™ NanoEVO™ Self Emulsifier and TASK™ MicroEVO™ Self Emulsifier
- Soluble electron donor and nutrients: EDS-QR™, Nutrimens® Granular, and Nutrimens® Liquid

Electron Acceptors for Anaerobic Oxidative Bioremediation
At petroleum-contaminated sites where oxygen has already been depleted, anaerobic oxidative bioremediation is often applied. In the absence of oxygen, anaerobic oxidative bioremediation relies on other electron acceptors such as nitrate or sulfate for direct microbial metabolic oxidation of a contaminant (USEPA, 2013). Amendments with soluble sulfate and electron donor such as Nutrisulfate® are often added to the affected area to stimulate sulfate-reducing conditions to help microbes metabolize the petroleum compounds.
SiREM, a company Tersus represents, provides the tools environmental professionals need to optimize remediation of chlorinated solvents and other recalcitrant chemicals. As an industry leader, SiREM provides unparalleled technical support, combined with a unique range of products and testing services, that save clients money, increase remediation effectiveness and provide peace of mind during field implementation.
Bioaugmentation Cultures
The complete reductive dechlorination of chlorinated ethenes yields non-toxic ethene as a final product. Absent the right bacteria, you could see an accumulation of vinyl chloride. Although not necessary at every site, Tersus recommends the use of KB-1® bioaugmentation cultures.
KB-1® and KB-1® Plus bioaugmentation cultures by SiREM have been used for over a decade to enhance bioremediation of chlorinated solvents. These cultures introduce beneficial microorganisms to contaminated sites where they are absent or at low concentrations. Bioaugmentation with KB-1® and KB-1® Plus is an effective solution to enhance remediation of a growing range of chlorinated solvents and other recalcitrant compounds.
