Hexavalent chromium is the heavy metal constituting a major part of tannery effluent, poses a serious threat to the environment. Chromium has adverse health effects on plants, animals and human beings. It becomes a necessary task to reduce the Chromium in the environment. In the present study a preliminary attempt has been made to reduce the chromium using two selected micro organisms such as Arthrobacter citreus and Brevibacterium casei to screen the efficacy of bioremediation. In the present study instead of using the tannery effluent it has been planned to use the actual pollutant in the tannery, synthetic hexavalent chromium. From the study it is evident that in the Cell Suspension technique, using Brevibacterium casei showed 84% of Chromium(VI) reduction after 72 hours, whereas in the immobilization technique, the consortium showed 78% of Chromium(VI) reduction within 48 hours. The results indicate that immobilized consortium is effective since it reduces 78% of Chromium(VI) within 48 hours. Such type of pilot studies will form a base to identify an effective bioremediation procedure to reduce chromium in the tannery effluent. © 2010 RJPBCS.
