Résumé : |
Heavy metal pollution of ground and surface waters by industrial effluents has become a serious threat to the environment especially in developing countries. One example of heavy metal pollution is the high chromium containing liquid effluents discharged from tanneries. Though many conventional physico-chemical methods are currently being practiced, biotechnological methods are becoming attractive alternatives, as they are economical and eco-friendly. In this context, the search for innovative and eco-friendly biotechnologies to remove toxicants from effluents has focused attention on the detoxification capacity of a variety of microbes especially cyanobacteria. In the present work, preliminary studies were carried out using two species of cyanobacteria for the treatment of tannery effluents with special reference to trivalent chromium. The effects of different concentrations of chromium on the growth response of these species in terms of biomass and chlorophyll-a were studied in addition to their capacity to accumulate chromium. These species were very effective in removal of trivalent chromium (95 - 100%) besides reducing BOD and COD of the effluent. SDS-PAGE and FTIR studies indicated the formation of a complex with protein. Better performance of the species in the field conditions gives positive indication of their usefulness in treatment of tannery effluent. |
