Recent Trends in Microalgae Research for Sustainable Energy Production and Biorefinery Applications
Microalgae are convincing biomaterials furnished with tremendous potential of performing environmental services and energy recovery to promote carbon neutral bio-economy. They have the ability to fix atmospheric CO2, water reclamation, bioremediation, and production of biomolecules, which offer distinguished features for biorefinery applications. However, several technical challenges in microalgae bioprocesses impede their application at large scale. The most notable challenges include low bioconversion efficiency and biomass productivity, susceptibility to harmful microorganisms, high-energy input in the form of light and nutrient supply, and high cost accounted for biomass harvest. In the framework of microalgae-based sustainable bio-economy, technology integration turns out to be the only viable solution. The integration of microalgal technology with other related field would unveil their meritorious attributes and would offset the cost of biomass processing. The focus of this chapter is to identify the recent environmental technologies which can be integrated with microalgae biorefinery to drive the objectives of resource-efficient bio-economy. The prospects of these technologies are presented to realize their future potential and sustainability outlook.
