Cr(VI), one of the most common ground waters heavy metal contaminant due to its indiscriminateuse in different  industries  has  become  a  matter  of  major  environmental concern. So, it is desirable   that remediation methods  should  be  such  that  brings  its  level  within  the permissible  limits  before   effluents are  discharged.  The methods should be cheap as well as eco-friendly. Nowadays, severalbiological remediation strategies are used by applying microorganisms for its removal involving biosorption and biotransformation. Biosorption is dependent on surface nature of the biosorbentswhereas biotransformations depend on the presence of reductants. The present review includes bioremediation strategies of Cr(VI) based on biosorption or biotransformation or both by non-pathogenic bacteria only.
Keywords: Cr(VI), Heavy metal, Biosorption, Biotransformation, Bioremediation.
