Soil contamination by heavy metals is becoming one of the most severe environmental issues. Since heavy metals cannot be degraded and can persist indefinitely in soil environments, how to remediate heavy metals polluted soils has become a difficult and hot issue in environmental pollution control area. Phosphate solubilizing microorganisms(PSMs) can dissolve insoluble phosphorus and transform it into soluble fractions by utilizing their own metabolites or through the synergistic effects with other microbes and plants. PSMs also has multiple functions in plant growth-promotion and heavy metal detoxification. PSMs can improve the resistance ability of plants against various diseases and strengthen the survival competitiveness of phytoremediation plants under toxic levels of heavy metals. This paper provides an overview of PSMs research status, and summarizes the remediation effects and mechanisms of heavy metal contaminated soils by PSMs. The disadvantages of PSMs for remediating heavy metal contaminated soils are also analyzed and the future research orientation are pointed out accordingly.
