Poplar Trees Clean Carcinogen
Poplar tees, inoculated with a probiotic, degraded the carcinogen, trichloroethylene, TCE, at a California contaminated site. Sharon Doty, University of Washington, is using phytoremediation as inexpensive green technology for cleaning soil and water pollution from the environment. Plants naturally contain pollutant destructive bacteria, a process called phytoremediation. Doty soaked poplar tree cuttings with a probiotic that degrades TCE. The Poplars treated grew faster and larger than untreated trees. The water tested downstream was below EPA standards of safety.
