Removal of chromium and pentachlorophenol from tannery effluents

Three bacterial strains, including one Acinetobacter sp. PCP3, grown in the presence of minimal salt medium and pentachlorophenol (PCP) as sole carbon source in the chemostat showed higher utilization of PCP and adsorption of chromium. In sequential bioreactor, tannery effluents treated initially by bacterial consortium followed by fungus removed 90% and 67% chromium and PCP respectively, whereas in another set of bioreactor in which effluents was treated initially by fungi followed by bacteria could remove 64.7% and 58% chromium and PCP, respectively.
