The Impact of Bioaugmentation on Metal Cyanide Degradation and Soil Bacteria Community Structure

  title={The Impact of Bioaugmentation on Metal Cyanide Degradation and Soil Bacteria Community Structure},
  author={Joanne Baxter and Stephen Peter Cummings},
Metal cyanides are significant contaminants of many soils found at the site of former industrial activity. In this study we isolated bacteria capable of degrading ferric ferrocyanide and K2Ni(CN)4. One of these bacteria a Rhodococcus spp. was subsequently used to bioaugment a minimal medium broth, spiked with K2Ni(CN)4, containing 1 g of either an uncontaminated topsoil or a former coke works site soil. Degradation of the K2Ni(CN)4 was observed in both soils, however, bioaugmentation did not… CONTINUE READING
