Electron Donors

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.
