Extracellular Continuum of Microalgae and Cyanobacteria

Microalgae and cyanobacteria are increasingly recognized as strategic resources for the future of biotechnology, yet their extracellular products remain insufficiently explored. This book sheds light on the remarkable diversity and significance of the extracellular continuum, encompassing both extracellular polymeric substances (EPS) and low-molecular-weight extracellular organic metabolites (LMW-EOM). From biofilm structuring, metal binding, and stress protection to photoprotection, signaling, and microbial interactions, these compounds play essential roles in both ecosystem functioning and applied innovation.Bridging fundamental science and industrial perspectives, the book examines their biosynthesis, physicochemical properties, ecological functions, extraction methods, analytical challenges, and regulatory dimensions. It also highlights promising applications in cosmetics, pharmaceuticals, food technology, environmental remediation, and the emerging blue bioeconomy.Comprehensive and forward-looking, this volume offers researchers, students, and industry professionals an essential reference on the extracellular potential of microalgae and cyanobacteria.
