Recent advances of plant growth promoting rhizobacteria (PGPR) for eco-restoration of polluted soil

Abstract

The emergence of several complex environmental pollutants from various industrial activities has posed a global challenge for ecorestoration and sustainable development. The use of Plant Growth-Promoting Rhizobacteria (PGPR) for the remediation of soil pollution has gained recognition as a promising biotechnological tool for sustainable development. Recent advances in metagenomic approaches have allowed for the detection of rhizospheric bacterial communities from polluted soils revealing their contributions to the degradation of complex pollutants through the production of potential enzymes as a novel technique. In addition, protein/enzyme engineering and the fate of heavy metals accumulation in plant tissues, through bacterial-assisted phytoremediation, has expanded the role of PGPR in soil reclamation by improving their efficacy, understanding their mechanisms of action, and integrating them with other innovative approaches been reported as advance technique. These advancements give strong evidence for more efficient and sustainable soil remediation strategies, aiding in the restoration of contaminated soil and ensuring environmental sustainability. These techniques and PGPR attributes will provide a green technology for environmental safety.
