Abstract:

In the lands exposed to heavy agricultural production, pesticide residues (heavy metals) in the soil have become undeniable. Bioremediation is a natural process, where the degradation of a chemical or pesticide by microbial organisms. Plant growth-promoting rhizobacteria (PGPRs), in those, stand out with bioremediation feature which is degradation of the heavy metals into harmless products by secreted metabolites such as enzymes. PGPRs are soil bacteria that habitat the roots surrounding soil and/or root surface. Rising interest on biodegradation via PGPRs have attracted attention in recent years for remediation of contaminated soils with pesticide residues. Even the number of studies associated with bioremediation by PGPRs is limited; the current studies demonstrate PGPRs have the ability to convert the harm of the pesticide residues into the harmless state. Consequently, on the basis of relevant studies to date, the use of beneficial rhizobacteria gives promise as a natural approach to overcome many abiotic / biotic problematic factors in agricultural production including pesticide residue.
