The use of root-colonizing recombinant bacteria to enhance rhizosphere degradation of polychlorinated biphenyls
"Rhizoremediation is an attractive option for the remediation of polychlorinated biphenyls (PCBs) in the shallow surface profile because it can potentially lead to complete in-situ destruction of the PCBs. By utilizing plant/microorganism systems, enhanced PCB rhizoremediation may be possible by constructing recombinant rhizosphere bacteria. The use of root-colonizing bacteria as the recipient for the degradation genes heightens the potential survival, transport and impact of the microorganisms because the plants provide a consistent environment, which is selective for the recipient bacteria...In this work, Sinorhizobium meliloti which has a well characterized nodulating relationship with Medicago sativa (alfalfa). S. meliloti 1021 was engineered with the bph genes. The recombinant S. meliloti retained similar growth rates as the wild-type strain. The engineered S. meliloti strains grew on biphenyl and monochlorobiphenyl"--Abstract, leaf iii.
