Evaluate The Potential Of Bioleaching Using Sulphide Oxidizing Bacteria To Treat Heavy Metals Contaminated Sludge
Abstract
Heavy metal bioleaching potential of four Sulphur Oxidizing Bacteria (SOB) isolated from local alum soil, and indigenous bacteria from Ba Bo canal were conducted in this study. Four isolates established significant Zn leaching capacity on contaminated Ba Bo sludge substrate. There was up to 90.64%, 86.23%, 81.72%, 70.06% leaching efficiency as compared with initial concentration of four identified bacteria Micrococcus luteus, Ralstonia pickettii, Bordetella trematum, and Lysinibacillus sphaericus respectively. However, the leaching capacity of indigenous bacteria from Ba Bo canal expressed not significant for environmental bioremediation.
