The steadily increasing presence of both natural and anthropogenic pollutants in our environment poses a considerable challenge, given the recalcitrance of many of these pollutants. Microbial bioremediation presents a promising and sustainable strategy that harnesses a diverse array of microorganisms, operating either concurrently or sequentially, to eliminate or mitigate the presence of pollutants within the environment. Recent years have witnessed the application of multiomics techniques to the study of biodegradation and bioremediation, yielding an abundance of novel data that enrich our comprehension of pivotal pathways and offer fresh perspectives on the adaptability of organisms amidst shifting environmental conditions. This book brings together recent progress in microbial bioremediation, emphasizing the emerging field of multiomics technologies. It serves as a valuable reference for microbiologists exploring multiomics applications and environmental scientists seeking innovative remediation solutions.
