Bioremediation of ammonia, nickel and hexavalent chromium from synthetic solutions by non-pathogenic microorganisms

Bioremediation seems to be a good alternative to conventional clean-up technologies. Bioremediation has advantage over conventional physical and chemical methods such as precipitation, adsorption, electrodialysis and reverse osmosis. The aim of this work was to remove ammonia, nickel and hexavalent chromium from synthetic solutions by bioremediation technique.
