The book 'Microalgae Source of Omega-3 Fatty Acids' by Madhusree Mitra is a comprehensive exploration of the role of microalgae as a sustainable source of essential fatty acids, particularly polyunsaturated omega-3 fatty acids such as EPA and DHA. The book covers a wide range of topics, including the biochemistry and biosynthesis of lipids in microalgae, the nutritional value and health benefits of omega-3 fatty acids, and the biotechnology and techniques involved in the cultivation, harvesting, and downstream processing of microalgae.The book discusses the role of cell biology, genetics, physiology, and lipid metabolism in determining the fatty acid profile and composition of different microalgae species. It also examines the use of microalgae in various industries, such as the food industry for functional foods and supplements, aquaculture feeds, biofuel production, bioremediation, and carbon capture. The potential for microalgae to be used in nutraceuticals and as a source of valuable lipids is also discussed, as well as the use of lipidomics and metabolomics in analyzing the lipid content and quality of microalgae.The book covers various techniques used for microalgae cultivation, including photobioreactors and open ponds, and discusses the factors affecting biomass productivity and yield. The book also explores the potential of microalgae biorefineries and the use of membrane technology for lipid extraction and downstream processing. Additionally, the book discusses the role of microalgae in nutrient removal and wastewater treatment, and the potential for nutrient recycling through microalgae cultivation. Overall, this book is an essential reference for researchers, students, and professionals interested in the potential of microalgae as a sustainable source of omega-3 fatty acids and other valuable compounds.
