High-value–added products from microalgae production integrated with bioethanol process

Two-third of the earth's biomass is composed of microalgae. In recent years, there has been considerable discussion about the competition between conventional and advanced biofuels based on bioenergy potential. This review studies biomass-based bioethanol production, especially third-generation bioethanol production which is centered on the utilization of marine organisms like algae. In addition to energy utilization microalgae contain vast nutritional compounds for food, feed aquaculture, cosmetics, and pharmaceutical products. The overview of this review was to present the general microalgae stock for commercial bioethanol and its high-value components for different applications.
