Microbial Remediation of Halogenated Compounds via Microbial Chain Elongation
Chlorinated solvents (e.g., tetrachloroethene (PCE), trichloroethene (TCE), and 1,2-cis-dichloroethene (cis-DCE) are widespread legacy groundwater pollutants. The most common groundwater treatment for bioremediation of PCE and TCE is in situ anaerobic reductive dechlorination by Dehalococcoides mccartyi. Hydrogen (H2) is a crucial electron donor...

Controlling Microbiological Processes for In Situ Contaminant Treatment
Groundwater remediation is the process that is used to treat groundwater by removing pollutants. There are different groundwater remediation methods, but they all have the same goal: clean polluted water. One method is bioremediation wherein a biological system is employed for removing environmental pollutants. In situ remediation of subsurface...
