Multi-omics analysis of Stenotrophomonas maltophilia S-11 reveals its potential for Pb bioremediation in contaminated soil.

Lead (Pb²⁺) contamination in soil poses a significant environmental threat, but bioremediation using plant growth-promoting bacteria offers a sustainable solution. We evaluated the Pb²⁺ detoxification potential of Stenotrophomonas maltophilia strain S-11, isolated from the buckwheat rhizosphere. The strain exhibited high Pb²⁺ tolerance, with a minimum inhibitory concentration of 18 mM, along with a Pb²⁺ removal efficiency of 78.
