Response of the PCB-contaminated soil bacterial community to applied bioremediation treatments

For full field implementation of the bioremediation as a strategy for cleaning PCB-contaminated soils, the impact of the applied treatment on the microbial community needs to be clarified. An ideal bioremediation should have positive effects on PCB-removal but should pose no treats to the health of the soil ecosystem. Microbes, playing an essential role in maintenance of the soil ecosystem, are the first indicators of a negative impact of soil manipulation to ecosystem. A small-scale bioremediation experiment was conducted in order to get insight into behavior of the microbial community during bioremediation of PCB-contaminated soil, targeting both functional PCB-degrading community (by bph…
