Bioremediation of Cr(VI) pollutant, present in the effluent of electroplating and tannery industries majorly is the most cost-effective eco-friendly, and promising solution to reduce the toxic effect posed on the ecosystem by chromium (VI). Several acidophilic bacterial species have shown great potential to adapt and reduce class-A carcinogen Cr(VI) in the effluent to its nontoxic form Cr(III). Immobilized extracellular enzymes secreted by microbes during the development of the mechanism and the microbial cells both were used to accomplish the biological reduction of Cr(VI). All the bacterial species were isolated from the effluent sample and characterized as Bacillus megaterium C31171 (CRS-W), Staphylococcus species SeLB4 (CRS-Y1), and Burkholderia species (CRS-Y2) using 16S rDNA sequencing. Microbes-cells and extracellular enzymes secreted by microbes were separated. The growth of microbial species was monitored for the parameters like growth media and temperature.
