Bacterial Reduction of Hexavalent Chromium: A Viable Environmental Solution to the Treatment of Effluent from a Ferrochrome Smelter
نویسنده
چکیده
At first, laboratory-scale work under aerobic conditions was undertaken on bacteria imported from the USA. The system was optimised for variables including pH, temperature, nutrient type (e.g. glucose, molasses) and nutrient addition rate. As the effluent could contain phenols, tolerance to phenols at different concentrations was also investigated, including the possibility of utilising phenol as a source of nutrient. Bacteria were subjected to varying concentrations of Cr+ and the rate of Cr+ reduction was monitored. It was found that the Cr+-reducing ability of the original imported bacteria was inhibited by naturally occurring bacteria found in the industrial effluent.

The ability of Bacillus sp. MRKV isolated from tannery effluent which shows resistant towards hexavalent chromium potassium dichromate (K2Cr2O7) was evaluated in this study. The bacterial strain was assayed for its reducing ability towards K2Cr2O7. The study revealed that the isolated strain has the ability to reduce the hexavalent chromium and the optimal conditions required for the chromium r...
متن کاملHexavalent chromium reduction by bacteria from tannery effluent.
Chromium is generated from several industrial processes. It occurs in different oxidation states, but Cr(III) and Cr(VI) are the most common ones. Cr(VI) is a toxic, soluble environmental contaminant. Some bacteria are able to reduce hexavalent chromium to the insoluble and less toxic Cr(III), and thus chromate bioremediation is of considerable interest. An indigenous chromium-reducing bacteria...
