Chromium is important metal due to its high corrosion resistance and hardness. The trivalent chromium Cr III is required in trace amounts for sugar and lipid metabolism in humans and its deficiency causes disease. But due to environmental pollution caused as a result of hexavalent chromium CrVI is a highly toxic metal pollutant that affects the environment and is abundantly available in the environment and has toxicity and harmful effect on living system and its cleanup is highly essential such as contaminants contained hexavalent chromium CrVI. To alleviate such problems by applying essential microorganisms were easily degradable by naturally occurring bacteria and the isolated one. Considering its potential for hazardous toxicity and exposure CrVI has been designated as a priority pollutant in many countries. Chromium VI is toxic and harmful to human health mainly for the people who are working in industries where CrVI is widely used. Therefore this review article was initiated to study the application of isolated bacterial culture as biological tool for hexavalent chromium removal from tannery industry waste water and investigated to degrade Chromium VI and clean up the environments.
