Endophytes Help Poplar Trees Clean Up TCE on Superfund Site

Poplar trees can capture and remove trichloroethylene (TCE) from the soil and degrade it. Now, a method using endophytes, symbiotic microbes that live within a plant, has been successfully shown to boost the speed and effectiveness of this natural degradation process. Researchers led by Edenspace Systems Corporation, a Superfund Research Program (SRP)-funded small business, conducted the first large-scale experiment on a Superfund site using poplar trees fortified with a microbial endophyte to clean up TCE-contaminated groundwater.
