34 different isolates were obtained from collected sample. Out of which three strain of Pseudomonas spp. were isolated and used for evaluating their efficiency for reduction of hexavalent chromium. The effect of initial pH, temperature and incubation time on the bioreduction rate of hexavalent chromium was studied and process was optimized for bioreduction of hexavalent chromium. Maximum Hexavalent chromium removal of 42.30% by Pseudomonas isolates (UK3), 30.00% by Pseudomonas spp. (UK4) and 19.34% by Pseudomonas spp. (UK5) at 100 ppm of synthetic solution, during 5 days. On the basis of highest removal rate, Pseudomonas spp. (UK3) was selected and used for further study. The present study depicts that Pseudomonas spp. removes chromium efficiently and this could be used for industrial waste management and bioremediation of environmental contaminants.
