Edited by recognized leaders in the field, this penetrating assessment of our progress to date in deploying microorganisms to the advantage of environmental management and biotechnology will be widely welcomed by those working in soil contamination management, agriculture, environment management, soil microbiology, and waste management. The polluting effects on the world around us of soil erosion, the unwanted migration of sediments, chemical fertilizers and pesticides, and the improper treatment of human and animal wastes have resulted in serious environmental and social problems around the world, problems which require us to look for solutions elsewhere than established physical and chemical technologies. Often the answer lies in hybrid applications in which microbial methods are combined with physical and chemical ones. When we remember that these highly effective microorganisms, cultured for a variety of applications, are but a tiny fraction of those to be found in the world around us, we realize the vastness of the untapped and beneficial potential of microorganisms.

Microbial bioremediation and biodegradation in environmental monitoring offers an environmentally friendly approach for the monitoring and effective removal of contaminants. Various aspects of microbial-mediated bioremediation take advantage of the microorganisms’ ability to transform noxious compounds into utilizable intermediates and value-added products. Different microbial metabolites such as enzymes, biosurfactants, emulsifiers, organic acids, and solvents play significant roles in the decontamination of radioactive and heavy metals, chemical pesticides, and organic contaminants such as dyes and hydrocarbons in environmentally safe manners. Recent advancements in biochemical engineering, OMICS and genetic modification, and synthetic-biology pave ways for identifying indicator microbial strains, mechanisms of remediation, and the development of tailor-made microbe-metabolites for future applications. Microbial biotechnology in environmental monitoring and bioremediation thus represent a new way to rehabilitate and reconstruct “damaged” ecosystems. This work summarizes the latest research in the field of environmental bioremediation and offers fascinating insights on the behaviours of these unique microorganisms. It also presents exciting, new perspectives for the application of microbes in environmental protection. It is suitable for students, scholars, researchers and organizations involved in environmental protection.
Microbial Syntrophy-Mediated Eco-enterprising summarizes and reviews possible microbial applications for eco-industrial sustainability. The book emphasizes a wide spectrum of experimental and theoretical contributions from eminent researchers in the field. In 13 chapters, there is a focus on the microbial intrusions for remediating sites by accumulated pesticides, heavy metals, polyaromatic hydrocarbons, and other industrial effluents. Moreover, the potentiality and key mechanisms used by microorganisms for sustainable environmental management and their prospects are also considered in this new release. The term syntrophy for nutritional interdependence is often used in microbiology to describe the symbiotic relationship between bacterial species.

Environmental contaminants are chemicals that accidentally or deliberately enter the environment, often, but not always, as a result of human activities. Some of these contaminants may have been manufactured for industrial use, and because they are very stable, they do not break down easily. If released to the environment, these contaminants may enter the food chain. Other environmental contaminants are naturally occurring chemicals, but industrial activity may increase their mobility or increase the amount available to circulate in the environment, allowing them to enter the food chain at higher levels than would otherwise occur. Environmental contaminants influence the physiological cell reactions at different and heterogeneous basics and lead to altering in normal cell function primarily at the molecular and biochemical level. Molecular responses to such common environmental stresses have been studied intensively over the last few years, in which there is an intricate network of signaling pathways controlling perception of these environmental stress signals, the generation of second messengers and signal transduction. Recent advances in many areas of plant and microbial research, including genotyping, make scientists optimistic that valuable solutions will be found to allow deployment/commercialization of strategies better able to tolerate these environmental stresses. Environmental remediation was historically viewed as an inherently sustainable activity, as it restores contamination; however, researchers and practitioners are increasingly recognizing that there can be substantial environmental footprints and socioeconomic costs associated with remediation. Sustainability is an imperative in the emerging green and sustainable remediation movement, which is reshaping the entire remediation industry. Understanding the significant roles of sustainable or eco-friendly approaches in mitigating environmental contaminants, the current subject has recently attracted the attention of scientists from across the globe. This comprehensive volume “Sustainable Management of Environmental Contaminants: Eco-friendly Remediation Approaches" highlights the various prospects involved in current scenario. The current volume comprises the chapters from diverse areas dealing with biotechnology, microbial technology, nanotechnology, molecular biology, green and sustainable remediation, etc. I am hopeful that this volume will furnish the requisite of all those who are working or have interest in the current topic.

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.
Microbes and Microbial Biotechnology for Green Remediation provides a comprehensive account of sustainable microbial treatment technologies. The research presented highlights the significantly important microbial species involved in remediation, the mechanisms of remediation by various microbes, and suggestions for future improvement of bioremediation technology. The introduction of contaminants, due to rapid urbanization and anthropogenic activities, into the environment causes unsteadiness and distress to the physicochemical systems, including living organisms.
