Title

Investigation of Biological Removal of Chromium (VI) Using the Isolated Bacteria from Industrial Wastewater of Mobarakeh Steel Complex in Isfahan

Author(s)

Biological removal

Abstract

Introduction: Similar to some organic materials the heavy metals are not easily removed from the environment because of the toxic nature and form a class of stable and non-biodegradable pollutants. These elements enter the nature and the food chain as a result of natural activities such as eruptions of volcanoes and human activities such as mining, producing industrial and urban wastewaters and applying pesticides. Materials and Methods: In this study, chrome (VI)-resistant bacteria were isolated from the Industrial wastewater taken from Isfahan Mobarakeh Steel Complex. The isolated strains were identified and their resistance to chromium was determined and the strain with the highest resistance to chromium was used for its bioremediation. Data were analyzed using descriptive statistics and one way ANOVA. Results: The results of this study led to the identification of five chrome resistant strains that the Micrococcus luteus SEHD031RS bacterium was detected as the best chrome resistant strain due to the minimum inhibitory concentration of 140 mgLand minimum bactericidal concentration of 152 mgL-1. In this study, the highest chromium removal rate of 82. 5% was obtained at pH 4, concentration of 30 mgL-1 and 96 hours. Conclusion: The results of this study indicate that the Micrococcus luteus SEHD031RS strain can be used as an effective microorganism in removing chromium from Industrial wastewater or environmental bioremediation.
