Abstract

Heavy metals pollution of the soil is of environmental concern and various methods have been applied to reduce its concentration. This study examines the accumulation of metal ion from aqueous solution and remediation potential of indigenous Escherichia intermedium and Sḫigella soṉnei isolated from polluted site. Standardized 2 mL of inoculum was added to 30 ppm of metal (Cu, Cr, Cd, Pb, and Ni) solution and was incubated at 37°C, the solution was centrifuged and cells were filtered off. The supernatant was analyzed with Atomic Absorption Spectrometer (AAS) for the determination of residual metal concentration. Total metal concentration in the polluted soil was extracted using aqua regia (HCl:HNO3, 3:1) solution. Polluted soil solution was inoculated with 2 mL of standardized inoculum and was incubated at 37°C, the solution was subjected to gradient configuration and cells were filtered off. The resulting soil solution was subjected to acid digestion and analyzed with AAS for the determination of residual heavy metal concentration. Results from the bioaccumulation experiment show the absorbed concentration of metals from the aqueous solution by Escherichia intermedium as follows: 19.034 ± 0.26 mg/l (Cd), 5.799 ± 0.26 mg/l (Cr), 18.025 ± 0.17 mg/l (Cu), 9.930 ± 0.22 mg/l (Pb) and 11.179 ± 0.14 (Ni) as well as Sḫigella soṉnei with absorbed concentrations of 17.133 ± 0.17 mg/l (Cd), 8.937 ± 0.22mg/l (Cr), 17.686 ± 0.17 mg/l (Cu), 14.347 ± 0.02 mg/l (Pb), 10.776 ± 0.20mg/l (Ni). The range of percentage reduction of metal concentration in the ex-situ remediation of the four polluted soil sampled by Escherichia intermedium is as follows: 3.86-34.34% Cu, 18.06-50.39% Cr, 1.72-88.17% Cd, 2.89- 8.53% Pb, 19.31-44.03% Ni and Sḫigella soṉnei with 7.66-53.36% Cu, 17.39-50.11% Cr, 12.38%-ND Cd, 6.74-20.41% Pb and 44.17-53.13% Ni reduction. This study establishes that these isolates own good capability of accumulating and reducing metal ions from both aqueous solution and soil solution.
