Reduction of Hexavalent Chromium by Viable Cells of Chromium Resistant Bacteria Isolated from Chromite Mining Environment
Figure 5
Effect of inhibitor on chromate reduction by viable cells of Arthrobacter sp. SUK 1201. [Cr(VI) reduction was carried out in V. B. broth containing 100 μM Cr(VI). The initial cell density was maintained at 109 cells/mL. Incubation: 48 h at 25°C under continuous shaking (120 rpm). All inhibitors were sterilized separately and added to V. B. broth at equimolar (100 μM) level of Cr(VI). Residual Cr(VI) was estimated by usual diphenylcarbazide method. Results represent mean of triplicate experiments ± standard error].
