Microbial degradation of polychlorinated biphenyls in contaminated soil

The potential of microbial degradation of PCB in contaminated actual site soil was investigated by incubation in percolation columns for 10 months. The addition of traces of mineral salts and nutrients resulted in a significant increase of the degradation of PCB congeners up to 5 Cl-atoms caused by...

Description
Summary:The potential of microbial degradation of PCB in contaminated actual site soil was investigated by incubation in percolation columns for 10 months. The addition of traces of mineral salts and nutrients resulted in a significant increase of the degradation of PCB congeners up to 5 Cl-atoms caused by the naturally occurring bacteria in the soil matrix. If only tap water was recycled the degree of PCB degradation was negligible.
