The oceans are a rich source of biodiversity, and marine protists are no exception. These tiny unicellular organisms can be found throughout the marine environment and play a critical role in marine food webs. Additionally, they produce a variety of valuable compounds, including polyunsaturated fatty acids (PUFAs), which have important applications in the pharmaceutical, nutraceutical, and cosmetic industries. In this book, "Screening Characterization and Bioprospecting of Potential Marine Protists With Special Reference to Pufa", author Jazeera K. V. explores the potential of marine protists as a source of PUFAs. The book covers various aspects of screening, characterization, and bioprospecting of marine protists, with a specific focus on PUFAs. The book includes detailed descriptions of various marine protists and their potential as sources of PUFAs. It also discusses the methods used for screening and characterization of marine protists, along with the various bioprospecting techniques used to extract and purify PUFAs from these organisms. The book also includes case studies of successful applications of marine protists in the development of PUFAs for various industries. Overall, "Screening Characterization and Bioprospecting of Potential Marine Protists With Special Reference to Pufa" is a valuable resource for researchers, students, and professionals interested in marine biology, biotechnology, and the development of PUFAs from marine sources.
