Abstract

In recent years, a renewed interest is observed in microalgae to exploit its inspiring potential as a remarkable bioresource to produce high-value industrial products including protein, fatty acids (docosahexaenoic acid, eicosahexaenoic acid, etc.), pigments (β-carotene, astaxanthin, phycobilin, etc.), antiaging compounds, skin regeneration products, and bioenergy. The biomass productivity of microalgae is manifold greater than any other photosynthetic system. Moreover, algal biomass production offers several advantages over any other plants including higher productivity, higher rates of photosynthetic carbon fixation, efficient removal of nitrogen and phosphorus, when cultivation is done using municipal and industrial wastewater, and no competition with food, feed, or arable land of agriculture. Due to these promising factors, microalgae are considered as a remarkable bioresource to construct microalgae industry to generate huge revenue by technology development. This chapter describes the possible exploitation of this bioresource for energy and other high-value industrial products. Various challenges and opportunities of commercialization of algae-based products are also discussed.
