| Abstract | Pollution by heavy metal is an environment health threat due to their toxicity. Bioremediation through microbes is an ecofriendly method used to treat contaminated soils. Microbial consortiums are used as a natural strategy to remediate contaminated soil giving enhanced results compared with individual species. Bioremediation of heavy metals via Bacillus cereus and Micrococcus luteus were investigated. B. cereus and M. luteus were exposed to 3000 mg/L each of Lead nitrate, Mercuric Chloride and Sodium arsenate. Further, the organisms were exposed to 1000 mg/L of all three metals at 30°C for 96 hrs. Phytotoxicity of treated soil was also investigated. The microbial consortium combination of B. cereus and M. luteus has the maximum accumulation of As (1009.60 mg). Individually B. cereus and M. luteus demonstrated the highest uptake of As (729.45mg) and Hg (601.36 mg) respectively. The highest accumulation of the combined three heavy metals was observed by M. luteus. Soil phytotoxicity responses exposed that reduced heavy metal concentration correlate with decreased soil toxicity. The results indicated the efficiency of using the target organisms for the bioremediation of heavy metal and their probable agent for bioremediation. |
