Study of microorganisms degrading PCB in vegetated contaminated soil

Removal of PCBs from contaminated soil is one of the challenges ofenvironmental microbiology. In our study, we aimed to isolate,characterize and identify microorganisms from contaminated soiland to find out the plant effect on microbial diversity in theenvironment. Microorganisms were isolated by two ways, directextraction and isolation after cultivation with biphenyl as a solesource of carbon. Isolated bacteria were biochemically characterizedand the composition of ribosomal proteins in bacterial cells wasdetermined by mass spectrometry MALDI-TOF. Bacteria withrequired properties were chosen and the bphA gene was amplifiedand detected. Bacteria with detected bphA gene were then identifiedby 16S rRNA sequence analyses.
