Abstract

Heavy metal pollution in industrial effluent poses significant environmental and health risks. Bioremediation offers a sustainable and cost-effective approach to mitigate this problem. This research focuses on the bioremediation of heavy metals from contaminated domestic and industrial effluent using indigenous bacteria isolated from acclimatized activated sludge. Four resistant bacterial strains were selected and used in a mixture to evaluate their efficacy in heavy metal removal. The study employed various analytical methods to assess the efficiency of the bacterial consortium in metal removal. Results indicate that the indigenous bacterial mixture effectively removes heavy metals from contaminated effluent, offering a promising solution for heavy metal pollution control.
