From Pollution to Prosperity: The Role of PGPRs in Bioremediation

Environmental pollutionPollution caused by industrial, rural agricultural, and urban activities poses a significant intimidating remark to human health and ecosystem sustainabilitySustainability. Bioremediation has become a popular environmentally friendly and efficient in terms of coststrategy to mitigate the adverse impacts of environmental pollutantsEnvironmental pollutant. Plant growth-promoting rhizobacteria (PGPRs)Plant growth promoting rhizobacteria (PGPR) have gained attention as an effective means to enhance the bioremediation potential of the sites of contamination. In this chapter, we discuss the key aspects of PGPR-based bioremediation, including the selection of microbial strains, the nature and source of contaminants, and the mechanisms by which PGPRs enhance remediation efficiency. We examine the role of PGPRsPlant growth promoting rhizobacteria (PGPR) in phytoremediationPhytoremediation, using plants to get rid ofpollutants from contaminated water or soil, as well as ex-situ and in-situ remediationIn situ remediation approaches. We highlight the application of microbial enzymesMicrobial enzymes for the degradation of pollutants from the environment, including pesticides and heavy metalsHeavy metals (HMs), and the utilization of bioaugmentationBioaugmentation strategies to enhance remediation efficiency. We also discuss potential phytotoxic effects and biohazards associated with PGPR-based bioremediation and suggest ways to mitigate these risks. Furthermore, we discuss the impact of PGPRsPlant growth promoting rhizobacteria (PGPR) on soil nutrient stability, which is critical for promoting sustainable agricultureSustainable agriculture practices. Finally, we discuss the challenges and opportunities associated with the use of PGPRs for bioremediation and provide insights into future directions for research and application of this promising technology. PGPR-based bioremediation offers a promising strategy to promote environmental sustainabilitySustainability and enhance soil healthSoil health while mitigating the negative impacts of pollutionPollution. This chapter highlights the potential implications of PGPRsPlant growth promoting rhizobacteria (PGPR) in bioremediation for promoting sustainable agricultural practices and environmental stewardship.
