In the present study, we investigated the effect of the rhamnolipid biosurfactant on the threshold level for dechlorination at polychlorinated biphenyl (PCB) concentrations of 40, 60 and 120 ppm. When the extent of dechlorination was examined with the time course of incubations, the surfactant amendment enhanced the rate of dechlorination at all concentrations and the rate was also faster at higher...
The effect of sediment sources on the selection of polychlorinated biphenyl (PCB) dechlorinating competence was investigated using sediments from two different locations, the Grasse River and Owasco Lake. These two sediments had a similar organic carbon content but different particle size distribution. The two PCB-free sediments were spiked with Aroclor 1248 and inoculated with microorganisms from...
