Stimulation and molecular characterization of bacterial perchlorate degradation by plant-produced electron donors.


Root homogenate from poplar trees (Populus deltoides x nigra DN34, Imperial Carolina) stimulated perchlorate degradation in microcosms of soil and water samples collected at a perchlorate contaminated site, the Longhorn Army Ammunition Plant (LHAAP), located outside Karnack, Texas. Direct use of root products by perchlorate-degrading bacteria was shown for… (More)
