Abstract Five carbonate-biomineralization microbes were isolated from a mine soil, which was from Magu town of Bijie city, Guizhou province, China. The removal ability of 2# bacterial strain for Cd²⁺ was evaluated on the basis of biosorption and biomineralization. Experimental results showed that 2# strain had the strongest cadmium (Cd) tolerance in LB medium (250mg/L) among the five strains. The power-time growth curves indicated that the urea and Cd²⁺ inhibited the growth of 2# strain. Both the biosorption and biomineralization efficiencies declined with the increasing concentration of Cd²⁺. The strain had the best Cd²⁺ removal efficiency (45.14%) at its cell age of 4h. These results illustrated that the carbonate-biomineralization bacteria had a higher Cd²⁺ removal efficiency by biomineralization than that by biosorption. This study will offer a theoretical reference and practical guidance for remediating the heavy metal-polluted environments.
