英文摘要	Solidification and stabilization (S/S) treatment via cement is common and effective for improving soil strength and stabilizing heavy metals in contaminated soils, but has certain drawbacks, such as high fossil energy consumption, big carbon footprint, poor chemical compatibility, and ambiguous long-term stability. This paper innovatively proposes bacterial-induced mineralization (BIM) as an eco-friendly and efficient S/S method. In the BIM-S/S treatment, life activities of bacteria produce minerals to cement the soil particles and fix the heavy metals. This review firstly summarizes the basic theories of BIM technology followed by the evaluation on remediation effects and long-term stability in terms of soil solidification and heavy metal stabilization. Then the factors in BIM-S/S application are reviewed. Emphasis is put on the comparison of the BIM-S/S effect with that of cement-based-S/S technology. It is concluded that BIM-S/S technology is promising with outstanding performance in sustainability. On the other hand, current limitations and deficiencies with this technology are identified finally, hereby the directions for future research are pointed to make a major advancement in the BIM-S/S technology.
