Cadmium is a frequent soil contaminant, which is highly toxicity to humans and animals. Huttuynia cordata has a remarkable ability to hyperaccumulate Cd from soils. The present study shows that microorganisms play an important role in enhancing Cd accumulation by H. cordata from soil. The addition of bacteria to surface-sterilized short branches of H. cordata cutted in autoclaved soil increased the Cd concentration 50-fold as compared to axenic controls in the soil of 200 mg kg^-1 Cd; the ratio of total Cd accumulation in the shoots/roots of the plants in the soil of 50 mg kg^-1 Cd was enhanced 70%. Thus, the plant H. cordata has a great capacity of Cd uptake from soil, which may be enhanced by the microorganisms. The present study provided a novel, effective and environment-friendly method to phtoremediation the Cd contamination.
