Raising industrial activities and agricultural practices as well as other human anthropogenic actions adds a significant amount of heavy metals in soil and water, resulting in degradation of the environment. Some examples of the environmental concern metals are nickel, copper, arsenic, lead, cadmium, cobalt, and zinc. Due to their nonbiodegradable nature, toxic heavy metals accumulate in the environment and therefore contaminate the food chain. The presence of these hazardous metals further than the threshold limit exhibits a critical threat to the human health and total environment. Different physical, chemical, and biological procedures have been applied for the remediation of contaminants from the environment. Bioremediation is the application of biological remedy for cleanup and or mitigation of contaminants from the environment. This process is a cost-effective and worthwhile method for removal of heavy metal-contaminated soil compared to physicochemical remediation techniques which are expensive and deleterious for soil properties. Phytoremediation is defined as the direct use of appropriate living plants for removal, degradation, or sequester of contaminants from environments (atmosphere, hydrosphere, and lithosphere). The efficiency of phytoremediation depends on many factors like plant biomass yield, plant tolerance to metal toxicity, and heavy metal solubility or mobilization in the soil.

The success of the phytoremediation process can be attained through developing the association of hyperaccumularor plant species with microorganisms like heavy metal-resistant plant growth-promoting rhizobacteria.
