In order to explore the feasible methods for coremoval of cadmium(Cd) and arsenic(As) in soil, we selected Enterobacter sp. A11 and Comamonas sp. A23 due to their ability to oxidize Fe and Mn compounds, and studied immobilization capabilities for Cd and As of the production of biological Fe and Mn oxides （BFMO）. The SEM results showed that Fe-Mn oxides were located on the cell surface, leading to bacterial aggregation. Moreover, pot experiment showed strains A11 and A23 immobilized Cd and As in soils (reduce the proportion of bioavailable Cd and As, and increase the proportion of unavailable Cd and As), and exhibited a reduction in the accumulation of Cd and As in the aboveground and root parts of Brassica rapa L. The BFMO production of strains A11 and A23 exhibits excellent immobilization capabilities for Cd and As.
