Reduction of Hexavalent Chromium by Viable Cells of Chromium Resistant Bacteria Isolated from Chromite Mining Environment

Figure 3

Effect of electron donor supplementation on Cr(VI) 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. The electron donor was present at 0.1% w/v level, and 0.01% w/v glucose was present in control set. Incubation: 48 h at 25°C under continuous shaking (120 rpm). Residual Cr(VI) was measured by diphenylcarbazide method. Results represent mean of triplicate experiments ± standard error].
