Abstract
Among several soil pollutants, the heavy metal effluents discharged from different industries directly or indirectly influence the global environmental balance and eventually decrease agricultural productivity. As a result of these harmful activities, soil pollution due to heavy metal toxicity is a potentially crucial environmental issue globally. The conventional methods of removing the huge metals from the environment are not eco-friendly, and these processes produce huge toxic residues. So, in this situation, bioremediation is the most preferred way to minimise the effects of heavy metals on the environment. Under such circumstances, the impact of plant growth-promoting rhizobacteria (PGPR) in remediation of metal toxicated areas has gained importance in sustainable agriculture systems. PGPRs increase plant growth by solubilising phosphate, synthesising IAA, producing enzymes, fixing the nitrogen, etc. So, the inoculation of suitable and specific heavy metal-tolerant PGPR strains associated with plants can maximise the phytoremediation. In this work, the impact of PGPR on remediation of the heavy metal contaminated zone is adequately described.
