Bioremediation is the use of organisms for the treatment of soil pollution. Root colonizing symbiotic microorganisms such as arbuscular mycorrhizal fungi (AMF) are mainly involved in phytoremediation, that uses plants for soil remediation. Phytoremediation comprises a set of technologies that use various plants as a containment, destruction or extraction technique (EPA 2000). These techniques have received considerable interest in recent years because of potential cost savings compared to conventional non biological techniques. Different strategies of phytoremediation can be applied depending on the kind of pollutants. In all cases, vegetation reduces infiltration of water and erosion. Heavy metals cannot be degraded and can only be extracted (phytoextraction) from the soil or immobilized in a non toxic form (phytostabilization). AMF can help alleviate metal toxicity to plants by reducing metal translocation …
