The present book, Bioremediation for Sustainable Environmental Cleanup*,* has a compilation of seventeen chapters comprehensively describing the state-of-the-art on emerging bioremediation approaches employed for sustainable environmental clean-up of diverse environmental pollutants such as metal(loid)s, polycyclic aromatic hydrocarbons, dyes, pesticides, petroleum hydrocarbons, etc., by using bacteria, fungi, algae, higher plants, and novel materials like biohybrids, nano-biomaterials, and graphitic carbon nitride (g-C3N4). Different bioremediation strategies such as biosorption, bioprecipitation, bioaccumulation, biodegradation, biotransformation etc. have been described in detail. The emphasis throughout, however, is on sustainable environmental clean-up. Eminent researchers from various countries located in diverse geographical areas, including Argentina, Canada, Germany, India, Pakistan, South Africa, the United Kingdom, and the United States of America, have contributed towards the chapters of this book.
