Bioremediation of PCBs from Contaminated Soil

Abstract

The ability of different plant and bacterial species to degrade polychlorinated biphenyls (PCBs) in soil was studied for 7 mo. Plants were grown in an area contaminated with PCBs. The differences in microbial growth between nonvegetated and vegetated soil, and in the rhizoplane and rhizosphere, were also studied. The results from field conditions and pot expts. were compared with those obtained in lab. expts. performed with plant tissue cultures of the same species cultivated in vitro. The study demonstrated the beneficial effects of plants on microbial growth. [on SciFinder(R)]
