Abstract
Chromium is released into the environment by industrial and commercial processes. Due to their toxicity, they induce serious human disorders. Traditional physiochemical approaches are being replaced by biological Cr-removal, which is a cost-effective, long-term technology. Biological Cr-removal has been investigated extensively in resistant microorganisms (such as yeast, bacteria, fungus and algae). To cope with chromium toxicity, microbes have developed several strategies. Biotransformation, bioaccumulation and biosorption are some of the strategies that can be used to get rid of heavy metals. The present review is focused on recent breakthroughs in integrating/combining biological or natural processes with additional methods already in use which have a lot of potential for future research and could be used to treat trivalent chromium and hexavalent chromium contaminated water in an environmentally benign and cheapest way in the near future.
