Abstract

Background and Objective: Extensive use of hexavalent CHROMIUM in various industrial applications has caused substantial environmental contamination and the toxicity occurs in human due to environmental pollution via soil and water or due to occupational exposure because of these adverse effects, the EPA has identified Cr (VI) as one of the seventeen chemicals posing the greatest threat to human health. Bacteria can reduce chromate to the insoluble and less toxic Cr (III). The aim of this study was evaluated of chromate BIOREMEDIATION with use of Cr (VI) reduce microbial enhancement of efficiency process of DETOXIFICATION of Cr (VI) to Cr (III).Materials and Methods: 241 CHROMIUM RESISTANT BACTERIA isolated from INDUSTRIAL WASTEWATER of Qom were examined for their tolerance to hexavalent CHROMIUM and their ability to reduce Cr (VI) to Cr (III). The influence of various factors such as pH, time interval, temperature, aeration and initial metal concentrations on the reduction of CHROMIUM by the high tolerant bacterial isolate was studied.Results: A Gram-positive chromate reducing bacterial strain was isolated from effluents of textile, and identified as Staphylococcus arlettae strain R8-6A by phenotypic characterization and 16S rRNA analysis. Staphylococcus arlettae strain R8-6A could tolerate up to 770 mM of chromate and 93.6% reduced 0.3 mM highly toxic and soluble Cr (VI) (as Cr2O4) into almost non-toxic and insoluble Cr (III) in 48 h under aerobic condition. The maximum chromate removal were exhibited in Initial Cr (VI) concentration until 0.3 mM at 35oC, pH 6.5 and 50 rpm.Conclusion: The results indicate that the microbial consortia and the mono cultures of the above isolates can be useful for Cr (VI) BIOREMEDIATION of CHROMIUM contaminated environment.
