Biotechnological Strategies for Effective Remediation of Polluted Soils

This book presents a comprehensive collection of various in situ and ex-situ soil remediation regimes that deploy natural or genetically modified microbes, plants, and animals for biodegradation of toxic compounds or hazardous waste into simpler non-toxic products. These techniques are functionally effective under physical, chemical, and biological strategies. Soil and water contamination through heavy metals, hydrocarbons and radioactive wastes is of global concern as these factors have cumulative effect on the environment and human health through food chain-contamination. The book discusses the utilization of algae, plants, plant-associated bacteria, fungi (endophytic or rhizospheric) and certain lower animals for the sustainable bioremediation of organic and inorganic pollutants. In addition, it provides an updated account of some of the recent techniques like biochar and biofilms for the carbon sequestration, soil conditioning and remediation, and water remediation. It highlights the recent advancements in the nanobioremediation which is an emerging technology for remediation of pollutants with the aid of biosynthetic nanoparticles. Lastly, the book includes case studies and highlights the success of the treatment of polluted soils through these strategies.
