STUDIES ON BIOREMEDIATION TECHNIQUE ON HEXAVALENT CHROMIUM USING AUTOMOBILE INDUSTRIAL WASTE
Conventional methods for the removal of metal ions from the industrial effluents proving very expensive due to its high initial capital investment and high regenerative expenses. Hence in the present study a simple and economic technique i.e., bioremediation technique was applied for the removal of hexavalent chromium using automobile industrial waste. Bioremediation is emerging as one of the simple, economic and efficient method for the removal of metal ions from the industrial effluents. In the present study, bacteria is isolated from the root rhizoshere of Eichhorniacrassipers and estimated its capacity to grow in chromium containing effluents. Further its ability to remove chromium ions from industrial effluents was determined. The results revealed that bacteria can survive and multiply in both synthetic solutions and industrial waste effluents. The results revealed that the observed Pseudomonas bacteria can remove both trivalent and hexavalent chromium ions from the solutions efficiently.
