ISOLATION OF CHROMIUM RESISTANCE BACTERIA FROM LOAM SOIL SAMPLE OF RIVER GANGA

*Jishnu Sarathi Deb and Dr. Atanu Roy

ABSTRACT

Chromium resistance bacteria capable of reducing or transforming hexavalent chromium to trivalent chromium were isolated from soil and water. Soluble hexavalent chromium is extremely pernicious and shows mutagenic effects, due to its strong oxidizing nature. Heavy metals possess threat to the ecosystem as well as the plants animals, aquatic life and humans. At present day the bioaccumulation of heavy metals causes frequent environmental hazards. High concentration of these chromium is isolated from industrial and agricultural wastes. Chromium (VI) has physical as well as chemical contrasting characters to that of Chromium (III). The physiological reduction of Cr (VI) is highly expensive and thus the focus shifted for bioremediation of Cr (VI). Microorganisms reduces Cr (VI) to less toxic form. This reduced form Cr (III) has been reported to have dietary nutrient values. This work of review is attributed to find out how the resistance, reduction and remediation process is driven in microorganisms.
