Abstract

Abstract: In the recent century, global warming and climate change driven by extensive anthropogenic CO2 emissions have become threatening to the survivability of entire life forms, including humans. So, it is very much essential to diminish global carbon dioxide load. In this regard, bio-based low-cost CO2 capture and sequestration via photosynthesis to produce several value-added products like biofuel, biofertilizer, biopolymer, etc., have gained worldwide researchers' attention. Hence, in this dire environmental condition, many countries globally have established microalgae-based flue gas CO2 sequestration as one of the potential alternatives for sustainable development in the energy and environment sector. In the present review, all the aspects of microalgae-mediated flue gas CO2 sequestration, such as culture conditions, growth parameters, microalgal strains, and the effect of flue gas components, have been discussed. Also, the advantages and limitations of outdoor and indoor culture systems, including bioreactor designing approaches for enhancing CO2 fixation, have been thoroughly discussed. Graphical abstract: Unlabelled Image Highlights: Application of microalgal strains for bio-sequestration of flue gas CO2 is described. Various growth parameters affecting microalgae-based CO2 sequestration are described. Impacts of flue gas components on microalgal growth and CO2 biofixation are discussed. The advantages and disadvantages of flue gas CO2 fixation using microalgae are described. Co-culture techniques for enhanced CO2 sequestration using microalgae are explained.
