TLDR
In this article, the removal of contaminants by plants and microorganisms together is more effective than phytoremediation alone, which is a sustainable technique for removing contaminants from the polluted environments.Abstract:
Phytoremediation is a sustainable technique for the removal of contaminants from the polluted environments, but the removal of contaminants by plants and microorganisms together is more effective than phytoremediation alone. Phytoremediation is enhanced with the involvement of microorganisms in soil as well as in water. Rhizosphere microorganisms develop beneficial interactions with plants which ultimately results in increased plant growth and improved phytoremediation of heavy metals. Microorganisms play a vital role in mobilization and immobilization of metal contaminants from the environment for availability to different plants. Different microorganisms produce different metabolites which interact and make complexes with the contaminants and decrease their levels of toxicity by transforming them to less toxic state.read more

Rehabilitation of mine soils by phytostabilization: Does soil inoculation with microbial consortia stimulate Agrostis growth and metal(loid) immobilization?
TL;DR: In conclusion, microbial consortium inoculation stimulated the growth of endemic Agrostis plants and thus ameliorated the phytostabilization of a former mine soil highly polluted by As and Pb.

Phytoremediation of toxic elemental and organic pollutants.
TL;DR: Because elements are immutable, phytoremediation strategies for radionuclide and heavy metal pollutants focus on hyperaccumulation above-ground, in contrast, organic pollutants can potentially be completely mineralized by plants.

Perspectives of plant-associated microbes in heavy metal phytoremediation.
TL;DR: How such processes influence heavy metal uptake through various biogeochemical processes including translocation, transformation, chelation, immobilization, solubilization, precipitation, volatilization and complexation of heavy metals ultimately facilitating phytoremediation is illustrated.
