This book explores the applications of algal-derived biochemicals, which are now gaining attention for nutraceuticals, pharmaceuticals, cosmetics, bioplastics, biopolymers, bioglass, biofuels, and several other commercially valued compounds. This book will address the production of algal-based chemicals of industrial importance in terms of the recent advances, challenges, breakthroughs, and trends of applications for public health and environmental sustainability. The aim is to provide a comprehensive knowledge of several biochemicals, in particular, in terms of their category as-carotenoids, polyphenols, polysaccharides, fatty acids, biopolymers, and other secondary metabolites. It presents the techno-economic challenges, recent trends, and developments toward sustainable algal biochemical production with an emphasis on process development and product formulation. In addition, an in-depth analysis of market trends of algal biochemicals and algal bioeconomy has also been included. Facilitating the quantitative and qualitative analysis approaches for industrially important algae-to-biochemical production is the central idea of the book.
