Increasing population and industrialization are the key pollutant contributors in water bodies. The wastes generated by industries are highly hazardous for humans and the ecosystem and require a comprehensive and effective treatment before being discharged into water bodies. Over the years, many up gradations have been introduced in traditional water treatment methods which were expensive and ineffective especially for removal of toxic pollutants. Phycoremediation has been gaining attention due to its mutual benefit in wastewater treatment and for valuable algae biomass production. Wastewater, especially sewage and industrial effluents, is rich in pathogenic organisms, organic and inorganic compounds and heavy metals that adversely affect human and aquatic life. Microalgae use these inorganic compounds and heavy metals for their growth. In addition, they also reduce pathogenic organisms and release oxygen to be used by bacteria for decomposition of organic compounds in a secondary treatment. In this book, the potential of microalgae in wastewater treatment, their benefits, strategies, and challenges are discussed. The increasing need of finding innovative, low-cost, low-energy, sustainable and eco-friendly solutions for wastewater treatment makes the publication of a book on phycoremediation timely and appropriate. Features: (1) Deals with the most emerging aspects of algal research with special reference to phycoremediation. (2) Studies in depth diversity, mutations, genomics and metagenomics study (3) An eco-physiology, culturing, microalgae for food and feed, biofuel production, harvesting of microalgae, separation and purification of biochemicals.

For sustainable environmental management as a whole, the roles of phytoremediation and biofortification as two sides of the same coin must be highlighted. Phytoremediation is a process in which biological organisms are used to eliminate or nullify an environmental pollutant by a metabolic course of action. Biofortification, in contrast, is an agrarian process that enhances the micronutrient content of a food crop through plant breeding, genetic modification, use of enriched fertilizers, or management of agricultural practices. These two strategies, although targeting different objectives, both work on the same principle of the bio-extraction process that involves uptake, accretion, removal, and modification of micro- and macro-nutrient elements from the soil. This volume offers a comprehensive overview of phytoremediation and biofortification of Zn, Fe, Cu, and Cd, etc., and illustrates the emerging and innovative combination of these technologies. With chapters written by experts, the book highlights a wide range of topics and discusses the integration of advanced phytoremediation and biofortification approaches for sustainable ecological and health management. Topics include phytoremediation and biofortification strategies that use nanotechnology; algae, fungi, and other plants; CRISPR/Cas9-mediated genome engineering; and more for decontamination of water and soil and for fortifying plants against climate change, toxic chemicals, and other challenges. Key features: reviews and integrates the currently available information on phytoremediation and biofortification from molecular, biochemical, and physiological levels provides a direction towards implementation of programs and practices to enable the sustainable production of crops, resilient to climatic alterations This volume will be valuable for investigators who are working or have an interest in sustainable environmental management as well as for research students, teachers, scientists, and engineers, whether in academia, industry, or government, and those who have an interest in environmental remediation and micronutrient fields.
