Abstract:Three influencing factors, including different substituted elements, numbers and position of substituted elements were investigated to correlate structural features to degradation of polyhalogenated biphenyls by Rhodococcus sp. R04. For mono-substituents, degradation preference of R. sp. R04 were in the order 4-FB>4-CB34-MB>4-BrB. When the substituted elements were same, degradation rates of halogenated biphenyls reduced as halogen substitution increased. The strain was relatively insensitive to the halogen substitution pattern on the biphenyl ring, when halogenated biphenyls containing the same halogen substitution and numbers, the effect of the position of substituted halogen on the degradation of polyhalogenated biphenyls was great, especially 2,6-CB, which intensively showed striking resistance to degradation, eventually led to the reduction of degradation rates.
