The cultivation of phototrophic microalgae has been recognized as a promising platform for the production of renewable biofuels and a variety of valuable products through a series of biorefinery processes. To enable microalgal growth at the maximum productivity level to enhance economic competitiveness, the design of photobioreactors for efficient and cost-effective phototrophic cultivation is one of the most important issues in practice. This article elucidates comprehensive information on the characteristics of microalgae cultivation as well as the key factors and challenges that should be addressed regarding the phototrophic process. The design principle of the photobioreactor (PBR) for achieving highly efficient cultivation is also summarized. Many of today’s PBRs are open systems due to the cost issue; even so, closed photobioreactors have recently attracted considerable attention for the production of valuable compounds. The comparison of designs and features of the open and closed systems are discussed. Furthermore, the current development status of commercial microalgae cultivation systems by several companies is given as examples to expose the potential of and the challenges in using microalgal biomass. The objective of this chapter is to provide useful knowledge and information with regard to the design of PBR for microalgae cultivation with critical evaluations of those systems to facilitate the future development of the microalgae industry.

This book critically discusses different aspects of algal production systems and several of the drawbacks related to microalgal biomass production, namely, low biomass yield, and energy-consuming harvesting, dewatering, drying and extraction processes. These provide a background to the state-of-the-art technologies for algal cultivation, CO2 sequestration, and large-scale application of these systems. In order to tap the commercial potential of algae, a biorefinery concept has been proposed that could help to extract maximum benefits from algal biomass. This refinery concept promotes the harvesting of multiple products from the feedstock so as to make the process economically attractive. For the last few decades, algal biomass has been explored for use in various products such as fuel, agricultural crops, pigments and pharmaceuticals, as well as in bioremediation. To meet the huge demand, there has been a focus on large-scale production of algal biomass in closed or open photobioreactors. Different nutritional conditions for algal growth have been explored, such as photoautotrophic, heterotrophic, mixotrophic and oleaginous. This book is aimed at a wide audience, including undergraduates, postgraduates, academics, energy researchers, scientists in industry, energy specialists, policy makers and others who wish to understand algal biorefineries and also keep abreast of the latest developments.

Extensive effort is being made globally to develop various biofuels as an inexhaustible and renewable energy source. Biofuels are viewed as promising alternatives to conventional fossil fuels because they have the potential to eliminate major environmental problems such as global warming and climate change created by fossil fuels. Among the still-developing biofuel technologies, biodiesel production from algae offers a good prospect for large-scale practical use, considering the fact that algae are capable of producing much more yield than other biofuels such as corn and soybean crops. Although research on algae-based biofuel is still in its developing stage, extensive work on laboratory- and pilot-scale algae-harvesting systems with promising prospects has been reported. This chapter presents a discussion of the literature review of recent advances in algal biomass harvesting. The chapter focuses on stability and separability of algae and algae-harvesting methods. Challenges and prospects of algae harvesting are also outlined. The review aims to provide useful information for future development of efficient and commercially viable algal biodiesel production.

Biomass presents an authoritative and comprehensive overview of the possibilities for production and use of biomasses of agricultural and industrial importance. Issues related to environment, food, chemicals and energy present serious challenges to the success and stability of nations. The challenge to provide commodities to a rapidly increasing global population has made it imperative to find new technological routes to increase production of consumables while also considering the biospheres ability to regenerate resources. Plant and microbial biomasses are bioresources that may provide solutions to these critical challenges. Divided into five discreet parts, the book covers topics on production of unconventional biomasses and improving of conventional cultures, summarizing a range of useful products derived by biomass. This book provides an insight into future developments in each field and extensive bibliography. It will be an essential resource for researchers and academic and industry professionals in the life sciences.
