|(Cr(VI) reduction was carried out in V. B. broth containing 100 µM Cr(VI). The initial cell density was maintained at cells/mL. Separately sterilized metal solutions were added to V. B. broth at equimolar (100 µM) level of Cr(VI).|
Incubation: 48 h at 25°C under continuous shaking (120 rpm). Residual Cr(VI) was estimated by usual diphenylcarbazide method. Results represent mean of triplicate experiments ± standard error).
