This book covers wide aspects of algal technology and algae-based biorefinery aspects. Algae are the most prevalent, primitive, and abundant microbes on Earth, however, the commercialization of algal-based value-added products is still low due to the negligible dissemination of knowledge flow among the stakeholders and researchers. This book provides up-to-date information on the cultivation of microalgae, their harvesting, downstream processing, and diverse applications. It further discusses the macromolecules existing in microalgae, such as proteins, carbohydrates, and lipids, poly-unsaturated fatty acids, peptides, exo-polysaccharides, flavonoids and antioxidants. This book also highlights the advantages and some real-time challenges before the establishment of sustainable algal-based biorefineries. Further, it includes clear flow charts and figures in each chapter to aid in interpretation of every technical concept. This book motivates readers, entrepreneurs, and young farmers to exploit easily growing microalgae through cottage to large-scale biorefineries and start their own businesses for the production of value-added products.

Biofuels and Sustainability: Life-cycle Assessments, System Biology, Policies, and Emerging Technologies presents the current progress and challenges related to the sustainability of biofuels. Addressing a wide range of issues, the book examines the methods and technologies, policies for sustainable biofuels, impacts of advanced fuels, recent advances, and future research prospects. Reflecting new developments, emphasis is given to new biological/biochemical approaches that offer the most efficient, cost-effective, and sustainable strategies for biofuel production. Divided into five parts, the first provides an overview of biofuels, the need for alternate fuels, carbon footprints, life cycle assessments, environmental aspects, various generations of biofuels, biofuel production from lignocellulosic material, and artificial intelligence in biofuel production. Part 2 examines the various methods and technologies for biofuels production, with case studies from the USA, UK, and Brazil. Part 3 explores the policies for sustainable biofuels, including current standards, with applications from the USA, European Union, Asia, and Africa. Part 4 analyses the impacts of advanced fuels in the decarbonization of transport, climate change mitigation, sustainable agriculture, and water resources, with perspectives from developed and developing countries. Finally, Part 5 critically reviews the recent advances and future research prospects related to termites, insects, metabolic engineering, microorganisms, and bioreactors. - Provides carbon footprints and lifecycle assessments of biofuel and bioproduct production from 2nd and 3rd generation feedstocks and compliance with the international standards - Highlights the emerging applications of systems biology in biofuel and bioenergy production, including biomimetics and protein engineering - Analyzes the sustainable production of biofuels at various stages, such as feedstock production, biomass pre-treatment and novel bioprospection - Explains the technological challenges of biofuel production, designing novel bioreactors, and value-added processing of biofuel residues - Discusses and analyses biofuel and bioenergy policies from various countries and various regions of the world

This book enables readers to understand the theoretical aspects, key steps and scientific techniques with a detailed mechanism to produce biofuels from algae. Each chapter provides the latest developments and recent advancements starting from algal cultivation techniques to the production of value-added green fuels, chemicals and products with wide applications. The volume brings together a broad range of international and interdisciplinary experts, including chemical and biological engineers, biotechnologists, process engineers, environmentalists, pharmacists and nutritionists, to one platform to explore the beneficial aspects and challenges for an algal-based biorefinery. Chapters address cutting-edge issues surrounding algal cultivation, including genetic modification of algal strains, design and optimization of photobioreactors and open-pond systems, algal oil extraction techniques and algal-derived fuel products (biodiesel, bio-gasoline, jet fuels and bio-oil). Finally, the book considers the potential environmental impacts for establishing a sustainable algal biorefinery through lifecycle analysis, techno-economic assessment and supply chain management. This book will be an important resource for students, academics and professionals interested in algal cultivation, biofuels and agricultural engineering, and renewable energy and sustainable development more broadly.

Algae offer potential to produce renewable chemicals and fuels using solar energy and carbon dioxide from atmosphere or in flue gases while simultaneously reducing the generation of greenhouse gases. Since these can be grown on marginal lands with micronutrients and macronutrients often present in waste streams, algae-based chemicals and fuels do not compete with foods. Still large-scale production of algae-based fuels and chemicals faces considerable technological and economical challenges and it would by necessity require a biorefinery approach wherein all the possible algal components are converted into value-added compounds. The present series on algal biorefineries represents a forum for reporting the state of the art of different technologies as well as the latest advances in this field. The volume II of this series complements the volume I in terms of the current state of the art. Different chapters in this volume address diverse issues ranging from genetically modifies algae to new products to life-cycle analysis of algal products.

This book provides a comprehensive overview of value-added products from algae, presenting the fundamentals of algal cultivation, metabolism, harvest, and cellular pathways of phycochemicals biosynthesis. It offers sufficient details for both experts and non-experts to grasp the recent progress in this field. The book also discusses new phycochemicals and advancements in technology development, from separation to scale-up commercialization. Divided into 18 chapters, the book begins with an introduction to the value of algae as a renewable resource, followed by an authoritative overview of topics such as algae cultivation systems, harvesting techniques, phycochemical analysis, artificial intelligence in phytochemical recognition, and bioprocess engineering. Additional chapters cover various aspects of algal biotechnology, including biorefinery technology, biofuel-integrated routes, and the use of wastewater for algal growth. The book also explores high throughput screening methods for microalgae-based phycochemicals and examines the catalytic processes involved in algal bioprocessing. Cutting-edge topics such as omics approaches for algal applications, algal-based biopolymers, diatom nanostructured biosilica, and the potential of seaweeds in methane emission mitigation, are also explored. In this book, readers will discover the recent technological applications of algae in aquaculture and will find a case study on the functional food potential of Spirulina. Recognizing the importance of legislation and biosecurity in the field, the last chapter of the book addresses the regulatory frameworks and biosecurity measures necessary for the safe and sustainable development of algal biotechnology. Given its breadth, the book is a valuable resource for scholars, researchers and professionals interested in algal biotechnology, sustainability, biomass conversion, and new algal products from any perspective.
