Identification of heavy metal-mobilizing bacteria and revealing of their mechanisms for bioremediation of Pb–Cd co-contaminated soils with Brassica juncea

This work advances the development of sustainable solutions for remediating soils contaminated with harmful heavy metals like lead (Pb) and cadmium (Cd), which pose significant risks to environmental and human health. By developing a microbial-plant remediation strategy that leverages the synergistic effects of a mobilizing bacterium and a metal-accumulating plant, this research improves our ability to effectively detoxify contaminated soils. The insights gained into the underlying mechanisms provide a valuable foundation for designing efficient, environmentally friendly bioremediation strategies. Generally, this investigation contributes to safeguarding ecosystems, promoting soil restoration, and supporting sustainable land use in areas affected by heavy metal pollution.
