the dehalococcoides population in sediment-free mixed cultures metabolically dechlorinates the commercial polychlorinated biphenyl mixture aroclor 1260. | microbial reductive dechlorination of commercial polychlorinated biphenyl (pcb) mixtures (e.g., aroclors) in aquatic sediments is crucial to achieve detoxification. despite extensive efforts over nearly two decades, the microorganisms responsible for aroclor dechlorination remained elusive. here we demonstrate that anaerobic bacteria of the dehalococcoides group derived from sediment of the housatonic river (lenox, ma) simultaneously dechlorinate 64 pcb congeners carrying four to nine chlorines ... | 2007 | 17308182 |
