This book covers the multi-tasking nature of fungi for therapeutic applications. It emphasizes the simultaneous metabolic activities and functions of fungi for producing enzyme inhibitors, therapeutic molecules and other biomedical utilities like polymers, nano-composites and biosensors. The fungi are involved in the production of many therapeutically-potent secondary metabolites and polymers. The recent research on fungal bioprospecting is more focused on sustainable solutions for diverse industries and markets for the circular economy. This book also offers current and future research perspectives of fungal bioprospecting. The potential of fungi to act as a bioresource for antimicrobial, antiviral, anticancer, antiprotozoal and antituberculosis compounds has also been discussed. This book is a reference material for undergraduate students for gaining in-depth knowledge on fungal bioprospecting, particularly fungis multi-tasking nature.
