As blue biotechnology—the application of science and technology to living aquatic organisms for the production of knowledge, goods, and services—is gaining momentum in recent decades, this volume provides needed and the state-of-the-art information on the biotechnological potential of the as-yet understudied world of ascidians (sea squirts) of the different seas and oceans. It covers their biotechnological applications in the production and development of human food and as feed for aquatic farmed animals; for their therapeutic values from natural compounds in medicine; for their production of pure and high-quality cellulose that can be used in industrial products and by-products; for their bioremediating agents against marine pollution; as well as for their uses in bioethanol production. Biotechnological Potential of Ascidians: Wacky and Weird Sea Squirts is a valuable resource for scientists and researchers as well as students and faculty in marine biology and fisheries science as well as for industry professionals looking into exploring new marine sources for the development of food, feed, drugs, fuel, and more.
