Chromium exists in many forms according to their valence from 0 to VI. Most dominant and stable valences of Chromium are III and IV. Chromium is non degradable, harmful and toxic pollutants which negatively affect the environment. It transfers to one trophic level to another via the food chain and continues their cycle in the nature. Bacteria, fungi, algae and plants are the best constituents of biomass which reduces the toxicity of heavy metals in the ecosystem. Bioremediation is a natural process for waste treatment in an industrial area. This comprehensive review article describes the sources of chromium contamination in wastewater and soils, various treatment technologies for the removal of chromium from water/ wastewater and different bacteria dependent possible bioremediation of this metalin aneco-friendly and cost effective manner.
