Reduction of Hexavalent Chromium by Viable Cells of Chromium Resistant Bacteria Isolated from Chromite Mining Environment
Figure 4
Effect of temperature (a) and pH (b) 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. The initial temperature was maintained from 20–40°C and pH of the reaction medium was maintained in the range of pH 6.0 to 8.0. Residual Cr(VI) was measured by diphenylcarbazide method. Results represent mean of triplicate experiments ± standard error].
