Title: Microalgal biotechnology : bioprospecting microalgae for functional metabolites towards commercial and sustainable
applications / edited by Jeyabalan Sangeetha, PhD, Svetlana Codreanu, PhD, Devarajan Thangadurai, PhD.
Description: First edition. | Palm Bay, FL : Apple Academic Press ; Boca Raton, FL, USA : CRC Press, 2023. | Series:
Innovations in biotechnology | Includes bibliographical references and index. | Summary: “Microalgae are a valuable
resource of carbon materials that may be used in biofuels, pharmaceuticals, cosmetics, and health supplements. Still,
there are tremendous challenges in the microalgae production process, such as mass cultivation, strain improvement,
biomass disruption, and reprocessing of nutrients and water that have been the encumbering microalgal industry in
several ways. Microalgal biotechnology has the capability to introduce remarkable breakthroughs and innovations. This
volume brings together current advancements in the field of microalgal biotechnology to provide understanding of the
fundamentals and progress of the industry-oriented technologies. The volume covers biofuel production and its technical
challenges; current trends of microalgae in agriculture, aquaculture and food biotechnology; market space; biosafety and
other regulatory issues; and sustainability of microalgal products. The volume first provides insight into desmids and
other conjugating algae along with prospective trends of diatoms. It then goes on to explore the commercial applications
of microalgae that take advantage of their bioactive compounds, natural colorants, and functional metabolites. The role
of microalgae in agriculture, aquaculture, and the food sector are discussed, and tools from genome manipulation to
bioprocess engineering are studied. Several chapters focus on future prospects of biofuel and biodiesel production for
environmental and economic viability. The key features of the book: Presents the role of microalgae in various industries
including food, agriculture, aquaculture, biofuel, and metabolites Shows the historical and prospective use of microalgae
elements for economic and ecological benefits Explains the integrated technologies for massive production of microalgae-
derived products Includes the various industrial case studies to improve the sustainable production of microalgae products
Discusses current developments and confronts in microalgae bioprocessing Microalgal Biotechnology: Bioprospecting
Microalgae for Functional Metabolites towards Commercial and Sustainable Applications will be a useful reference for
academicians, researchers, industry professionals, postgraduate students, and policymakers who are interested in future
prospects of microalgae commercialization”-- Provided by publisher.
