The degradation of a mixture of hydroxy- and methoxy-PCB obtained as a result of a chemical modification of a commercial mixture of PCB «Sovol» by the Rhodococcus wratislaviensis strain KT112-7 in plankton culture or immobilized on carbon carriers has been investigated. It was established that the KT112-7 strain in plankton culture degraded 73.2% of a mixture of modified PCBs for 96 h; the strain immobilized on BAU-A activated carbon and on Carbopon-B-active carbon fiber provided the 59.5% and 95.3% degradation for the same time, respectively (with the starting concentration of PBS of 0.5 g/L). The application of the R. wratislaviensis KT112-7 strain immobilized on the BAU-A carrier decreased the number of the PCB derivatives by 1.5 times at the end of the experiment; the corresponding result for the Carbopon-B-active-immobilized culture was 3 times; the set of PCBs after the treatment with the suspension culture remained unchanged. In practice, the immobilization of R. wratislaviensis КТ112-7 strain on carbon carriers can be used in the development of the techniques for the degradation of chemically modified PCB mixtures. polychlorinated biphenyls, immobilization, destruction, utilization, PCB, Rhodococcus.
