📓 Marine biotechnology is an inter-disciplinary research area which has emerged as a unique academic subject. Marine biotechnology applications in various sectors are bio-prospecting, production of novel products by improving the growth of marine organisms, particularly food and feed products and diagnostics and biosensors. Considering the vast scope and innovative developments in the field of Marine Biotechnology, this book aims to bring out a comprehensive update of recent developments and emerging dimensions. This book has 16 chapters contributed by senior experts to young scientists working in the field of marine biotechnology. The chapters were well-focused on recent advances including marine microbial diversity, metagenomics, bioinformatics tools in metagenomics, in silico approaches in marine biodiscovery, marine toxins, marine natural products, marine microbial enzymes, marine biosurfactants, marine antibiotics and technological advances in fish cell lines. This book would be a unique reference-cum-text book for Masters Students, research students, scientists and academicians in Biotechnology and allied disciplines.
