Phytoremediation is an effective technique for remediation of heavy metals and organic pollutants from contaminated sites. It provides comprehensive information on practical and purposeful utilization of plant-associated bacteria and arbuscular mycorrhizal fungi for phytoremediation of environmental pollutants in the contaminated matrix. "Phytoremediation is inexpensive and beneficial in many environmental applications, as documented in this work addressing the cooperative action of different types of microorganisms and plants in contaminated soil. Beneficial effects of bacteria and fungi have been foundational to soil science, and advancing phytotechnology for the improvement of soil health is a subject of ongoing research. Many new studies have been reported since 1990, and a good review of this literature is appropriate and welcome. The ecology of the rhizosphere including positive interactions of bacteria and fungi is an ongoing area of phytoremediation research. Advances through genetic engineering to improve plant growth-promoting bacteria for use in phytotechnology applications are covered in a separate chapter. Many success stories are reported, and the text is supported by frequent tables that summarize progress on specific topics. Any student of soil ecology improvement would find this volume of interest." - L. E. Erickson, emeritus, Kansas State University, Choice, Oct 2021
