主　　题：Heavy metal contamination Bioremediation Biomineralization Mechanisms Influencing factor 

摘      要：Heavy metal contamination of soil and water is one of the most prominent environmental issues *** bioaccumulation and biomagnification of the food chain,heavy metals can be enriched hundreds of times and eventually enter the human body,posing a major threat to human *** has the greatest potential to become an efficient and environmentally friendly heavy metal remediation technology and has received much attention in recent *** review summarizes the latest progress of biomineralization technology on carbonate precipitation and phosphate precipitation in heavy metal *** microorganisms(including bacteria and fungi)and enzymes can induce carbonate and phosphate precipitation,converting the free heavy metal ions into insoluble ***,the mechanisms of the heavy metal remediation are significantly *** example,urea hydrolysis,which occurs intracellularly when urease-producing bacteria(UPB)are used,is the most commonly used mechanism for carbonate precipitation based *** contrast,phosphate solubilization by either enzymes or organic acids secreted by phosphate solubilizing bacteria(PSB)is extracellular,and both soluble and insoluble phosphorus can be decomposed by ***,some influencing factors such as the different species of microorganism,heavy metals and some environmental conditions that may affect the bioremediation of heavy metals were also summarized in this *** challenges of biomineralization based heavy metal remediation are also *** on the reviews of previous studies,a comprehensive understanding of heavy metal removal through microorganism can be increased,and thus promotes the applications of biomineralization technology in the treatment of large-scale heavy metal contaminated sites.
