This edited book details the plant-assisted remediation methods, which involves the interaction of plant roots with associated rhizospheric microorganisms for the remediation of soil and water contaminated with high levels of heavy metals, pesticides, radionuclides, agricultural by-products, municipal wastes, industrial solvents, petroleum hydrocarbons, organic compounds, and various other contaminants. Each chapter highlights and compares the beneficial and economical alternatives of phytoremediation to currently practiced soil, water, and air removal. This book covers state-of-the-art approaches in phytoremediation contributed by leading and eminent scientists from across the world. Phytoremediation approaches for environmental sustainability dealing the readers with a cutting-edge of multidisciplinary understanding in the principal and practical approaches of phytoremediation from laboratory research to field application. This book is of interest to researchers, teachers, environmental scientists, environmental engineers, environmentalists, and policy makers. Also, the book serves as additional reading material for undergraduate and graduate students of environmental microbiology, biotechnology, eco-toxicology, environmental remediation, waste management, and environmental sciences as well as the general audience.

This book discusses genetic engineering of both plants and microbes for making agricultural practices more productive and sustainable. It chapters explore the understanding of the interaction between plants and microbes, and genomic information to modify the metabolism of plants or microbes to further enhance the beneficial interaction. The book covers the development of commercial inoculants including selection of appropriate plant growth-promoting rhizobacteria/ phosphate solubilize bacteria based on target host plant, soil type, indigenous microbial communities, environmental conditions, inoculant density, suitability of carriers and compatibility with integrated crop management. This is a relevant content for scientists and researchers working on soil biology, sustainable agricultural and plant physiology. Also, this book is a useful read for graduate and post graduate students of agriculture, botany and microbiology.

Volume 3 covers recent research with expanded coverage on this important area of remediation. Mycoremediation is the form of bioremediation in which fungi-based technology is used to decontaminate the environment. Fungi are among the primary saprotrophic organisms in an ecosystem, as they are efficient in the decomposition of organic matter. Wood-decay fungi, especially white rot, secretes extracellular enzymes and acids that break down lignin and cellulose. Fungi have been proven to be a very cost-effective and environmentally-friendly way for helping to remove a wide array of toxins from damaged environments or wastewater. These toxins include heavy metals, persistent organic pollutants, textile dyes, leather tanning industry chemicals and wastewater, petroleum fuels, polycyclic aromatic hydrocarbon, pharmaceuticals and personal care products, pesticides and herbicides, in land, fresh water and marine environments. Bioremediation of toxic organics by fungi is the most sustainable and green route for cleanup of contaminated sites and we discuss the multiple modes employed by fungi for detoxification of different toxic and recalcitrant compounds including prominent fungal enzymes viz., catalases, general lipase, laccases, peroxidases and sometimes intracellular enzymes, especially the cyrochrome P450 monooxygeneses.Fungi play an important role in the biogeochemical cycling of manganese and other redox-active metals, which is related to their ability to survive radiation and other oxidative challenges.This book covers recent research with more detail on the various types of fungi and associated fungal processes used to clean up wastes and wastewaters in contaminated environments, and discusses their potential for environmental applications.

Combined fields of Microbiology and Nanotechnology have been most successful in providing novel solutions for protecting the health of humans and environment. This book covers the implications of nano-strategies to combat bacterial pathogens, applications of nanotechniques in microbiology, and innovative advances in the area of medical microbiology. Contents are divided into three sections -- Nanoscience in controlling bacterial pathogens, Nanoscience in Microbiology, Medical Microbiology. This volume is going to provide timely information about the technological advances of Nanoscience in the domain of Microbiology, with a special emphasis on Pathobiology. The book is a useful read for students and researchers in microbiology, nanotechnology and medical microbiology.          

This book explores the concept and methods of waste management with a new approach of biological valorization. Waste valorization is a process that aims to reduce, reuse, and recycle the waste into usable, value-added, and environmental benign raw materials which can be a source of energy.  The book brings together comprehensive information to assert that waste can be converted into a resource or a raw material for value addition. Waste valorization imbibes the natural recycling principles of zero waste, loop closing, and underlines the importance of sustainable and environmentally friendly alternatives. Drawing upon research and examples from around the world, the book is offering an up-to-date account, and insight into the contours of waste valorization principles, biovalorization technologies for diverse group of wastes including agricultural, municipal, and industrial waste. It further discusses the emerging paradigms of waste valorization, waste biorefineries, valorization technologies for energy, biofuel, and biochemical production. The book meets the growing global needs for a comprehensive and holistic outlook on waste management. It is of interest to teachers, researchers, scientists, capacity builders and policymakers. Also, the book serves as additional reading material for undergraduate and graduate students of biotechnology and environmental sciences.
