Phytoremediation and biodegradation of PCB in soil

This is a part of the research work focused on study of possible mutual relationships of microorganisms and plants in PCBs metabolism. Polluted soil was obtained from a site which has been contaminated by PCBs for a long time. This soil was used for isolation of bacteria whixh potentially participate in biolodegradation of PCBs. The same contaminated soil was used for experiments under real conditions. Within six months three plant species were cultivated-tobaco (Nicotiana tabacum), black nighshade (Solanum nigrum) and alfalfa (Medicago sativa) - and decrease of PCBs was measured
