Abstract

Graphical abstract: Highlights: Microalgae can utilize as resource of primary and secondary metabolites production. Co-production of primary and secondary metabolites can secure the economics of microalgal biorefinery. The required time to produce secondary metabolites can be reduced through various inductions. Microalgal biorefinery can be expanded through co-production. Microalgal biorefinery is applicable to various confined spaces and urban areas. Abstract: The interest in developing microalgae for industrial use has been increasing because of concerns about the depletion of petroleum resources and securing sustainable energy sources. Microalgae have high biomass productivity and short culture periods. However, despite these advantages, various barriers need to be overcome for industrial applications. Microalgal cultivation has a high unit price, thus rendering industrial application difficult. It is indispensably necessary to co-produce their primary and secondary metabolites to compensate for these shortcomings. In this regard, this article reviews the following aspects, (1) co-production of primary and secondary metabolites in microalgae, (2) induction methods for the promotion of the biosynthesis of secondary metabolites, and (3) perspectives on the co-production and co-extraction of primary and secondary metabolites. This paper presents various approaches for producing useful metabolites from microalgae and suggests strategies that can be utilized for the co-production of primary and secondary metabolites.
