Alfalfa (Medicago sativa L.) is an outstanding species used for the remediation of heavy metal-contaminated soil, and our previous research has shown that PGPR can promote plant growth under high-concentration lead stress. This discovery forced scientists to search strains compatible with alfalfa develop innovative bioremediation strategy lead-contaminated soil. study lead-tolerant rhizosphere soil red clover as experimental material; cultured, isolated, screened 52 excellent bacteria growth; then inoculated them into alfalfa. Marked differences existed in secretion auxin, protease, ACC deaminase among these strains. The results indicated Pseudomonas spp. (strain Y2), Y22), Bacillus Y23) exhibited a strong growth-promoting ability alfalfa, there was no antagonistic reaction three strains, enabling their coexistence. pot experiment manifested Y2, Y22, Y23, YH (a mixture could increase height, root length, fresh dry weight above ground, below ground They all significantly raise chlorophyll content antioxidant enzyme activity (p < 0.05) malondialdehyde (MDA) Furthermore, concurrent inoculation distinct types rhizobacteria (PGPR) diminished (Pb) concentrations enhanced levels available potassium (AK) phosphorus (AP), augmented capacity plants absorb Pb. imply be employed facilitate microbial-assisted other establish basis further on mechanism plants.

Phytoremediation is a sustainable technique that employs plants to reinforce polluted environments such as agroecosystems. In recent years, new strategies involving the plant microbiome an adjuvant in remediation processes have been reported. By leveraging this microbial assistance remediate soils contaminated with heavy metals As, Pb, Cd, Hg, and Cr, can sequester, degrade, or stabilize contaminants more efficiently. Remarkably, some species are known for their hyper-accumulative traits synergy partners successfully mitigate metal pollutants. This biotechnology based on plant-microbe associations not only aids environmental cleanup but also enhances biodiversity, improves soil structure, promotes growth health, making it promising solution addressing agro-pollution challenges worldwide. The current review article emphasizes potential of synergistic interactions developing practical solutions agricultural systems, which essential food security.
