Microalgae Biotechnology For Development Of Biofuel And Wastewater Treatment

This book addresses microalgae, which represent a very promising biomass resource for wastewater treatment and producing biofuels. Accordingly, microalgae are also an expanding sector in biofuels and wastewater treatment, as can be seen in several high-profile start-ups from around the globe, including Solix Biofuels, Craig Venter’s Synthetic Genomics, PetroSun, Chevron Corporation, ENN Group etc. In addition, a number of recent studies and patent applications have confirmed the value of modern microalgae for biofuels production and wastewater treatment systems. However, substantial inconsistencies have been observed in terms of system boundaries, scope, the cultivation of microalgae and oil extraction systems, production costs and economic viability, cost-lowering components, etc. Moreover, the downstream technologies and core principles involved in liquid fuel extraction from microalgae cells are still in their early stages, and not always adequate for industrial production. Accordingly, multilateral co-operation between universities, research institutes, governments, stakeholders and researchers is called for in order to make microalgae biofuels economical. Responding to this challenge, the book begins with a general introduction to microalgae and the algae industry, and subsequently discusses all major aspects of microalgal biotechnology, from strain isolation and robust strain development, to biofuel development, refinement and wastewater treatment.

This book is designed with the objective of studying microalgae and its application in the widest sense. Microalgae offer various inherent advantages as they are capable of accumulating lipids (20–70%), and able to aid with the production of pigments, carbohydrates, and proteins. The book comprehensively covers microalgae isolation techniques, their cultivation, and wastewater treatment by microalgae as well as the impact on biomass, lipid extraction, biofuel, and utilization of residual biomass focusing on biorefinery approach. The volume discusses the conversion of defatted oiled microalgae biomass for different applications. Acknowledging these challenges, this book discusses the limitations, outcomes, and economic aspects

This two-volume work presents comprehensive, accurate information on the present status and contemporary development in phycoremediation of various types of domestic and industrial wastewaters. The volume covers a mechanistic understanding of microalgae based treatment of wastewaters, including current challenges in the treatment of various organic and inorganic pollutants, and future opportunities of bioremediation of wastewater and industrial effluents on an algal platform. The editors compile the work of authors from around the globe, providing insight on key issues and state-of-the-art developments in algal bioremediation that is missing from the currently available body of literature. The volume hopes to serve as a much needed resource for professors, researchers and scientists interested in microalgae applications for wastewater treatment. Volume 2 addresses the various biorefinery aspects and applications of algal-based wastewater treatment in industrial and domestic contexts. The analyses are approached from multiple perspectives, including biotechnology, commercial, economic, and sustainability. The authors discuss the potential of microalgae for integrated biomass production utilizing various resources to treat wastewaters, and include evaluations of the economical and commercialization potential for such processes.

This book deals with the most emerging aspects of algal research with special reference to microalgae viz; diversity, mutations, genomics and metagenomics study, eco-physiology, culturing, microalgae for food and feed, biofuel production, harvesting of microalgae, separation, and purification of biochemicals, techno-economical assessment, microalgal biotechnology, algal-bacterial systems for wastewater treatment. It describes the complex issues associated with the above-mentioned areas with the intervention of cutting-edge biotechnological tools and techniques like next-generation sequencing methods, metabolomics, and bioreactor design and development. The chapters provide past developments, current information and future prospects of algal technology as an alternate avenue for waste water treatment and its potential for production of biofuel and nutraceuticals.

Valorization of Microalgal Biomass and Wastewater Treatment provides tools, techniques, data and case studies to demonstrate the use of algal biomass in the production of valuable products like biofuels, food and fertilizers, etc. Valorization has several advantages over conventional bioremediation processes as it helps reduce the costs of bioprocesses. Examples of several successfully commercialized technologies are provided throughout the book, giving insights into developing potential processes for valorization of different biomasses. Wastewater treatment by microalgae generates the biomass, which could be utilized for developing various other products, such as fertilizers and biofuels. This book will equip researchers and policymakers in the energy sector with the scientific methodology and metrics needed to develop strategies for a viable transition in the energy sector. It will be a key resource for students, researchers and practitioners seeking to deepen their knowledge on energy planning, wastewater treatment and current and future trends.

Microalgae are an invaluable biomass source with potential uses that could lead to environmental and economic benefits for society. Biotechnological Applications of Microalgae: Biodiesel and Value Added Products presents the latest developments and recent research trends with a focus on potential biotechnologically related uses of microalgae. It gives an analysis of microalgal biology, ecology, biotechnology, and biofuel production capacity as well as a thorough discussion on the value added products that can be generated from diverse microalgae. The book provides a detailed discussion of microalgal strain selection for biodiesel production, a key factor in successful microalgal cultivation and generation of desired biofuel products. It also describes microalagal enumeration methods, harvesting and dewatering techniques, and the design, and the pros and cons, of the two most common methods for cultivation—open raceway ponds and photobioreactors. Chapters cover lipid extraction and identification, chemical and biological methods for transesterification of microalgal lipids, and procedures involved in life cycle analysis of microalgae. They also examine the importance of microalgal cultivation for climate change abatement through CO2 sequestration and microalgae involvement in phycoremediation of domestic and industrial wastewaters. The book concludes with a general discussion of microalgal biotechnology and its potential as a modern "green gold rush." The final chapter provides an overview of advanced techniques such as genetic engineering of microalgae to increase lipid yield. This book provides a one-stop benchmark reference on microalgal biotechnology, considering all aspects, from microalgal screening to production of biofuels and other value added products.

This book presents an authoritative and comprehensive overview of the production and use of microalgal biomass and bioproducts for energy generation. It also offers extensive information on engineering approaches to energy production, such as process integration and process intensification in harnessing energy from microalgae. Issues related to the environment, food, chemicals and energy supply pose serious threats to nations’ success and stability. The challenge to provide for a rapidly growing global population has made it imperative to find new technological routes to increase the production of consumables while also bearing in mind the biosphere’s ability to regenerate resources. Microbial biomass is a bioresource that provides effective solutions to these challenges. Divided into eight parts, the book explores microalgal production systems, life cycle assessment and the bio-economy of biofuels from microalgae, process integration and process intensification applied to microalgal biofuels production. In addition, it discusses the main fuel products obtained from microalgae, summarizing a range of useful energy products derived from algae-based systems, and outlines future developments. Given the book’s breadth of coverage and extensive bibliography, it offers an essential resource for researchers and industry professionals working in renewable energy.
