Two bacterial strains named temporally as WTS and YTS were separated from the soil, and they could utilize tea saponin for growing and showed significant promotion effect on the biodegradation of PCBs. Under the condition of coexistence with tea saponin, the degradation rate constants of PCB 77, PCB 118 and PCB 138 were increased by 4.3 times, 4.8 times and 2.8 times, respectively, by WTS, and 7.1 times, 9.1 times and 8.9 times. respectively, by YTS compared to those treatments without tea saponin. The results indicated that tea saponin could promote the biodegradation of PCBs, implying that tea saponin might be a potential inducer for the biodegration of PCBs.
