摘要：

Microbial-assisted functional materials are emerging for addressing heavy metal pollution in soils. However, the mechanisms underlying their enhanced performance remain insufficiently understood. Here, we elucidated the synergistic mechanisms by which a phosphate-solubilizing bacterium ( Ochrobactrum anthropi , 2 % v / w ) and iron-doped hydroxyapatite (Fe-HAP, 3 % w /w) enhance the immobilization of lead (Pb), cadmium (Cd), and arsenic (As) through experimental evaluation and theoretical modeling. This strategy achieved immobilization effici...
