CO2 sequestration by hybrid integrative photosynthesis (CO2-SHIP): A green initiative for multi-product biorefineries

Abstract

Diversification among organisms has resulted in uniqueness and complexity between them leading to maintenance of continuous energy supply while restoring equilibrium in the environment. Photosynthetic organisms are capable of naturally converting atmospheric CO2 in presence of sunlight and water leading to production of organic molecules whereas artificial photosynthesis yields solar fuels by directly converting light through photovoltaic cells. Therefore, hybrid integration of both photosynthetic mechanisms involving catalytic processes by converting light energy which is an unlimited source of energy leading to the production of fuels and various valuable products, will be an amicable solution for efficient CO2 sequestration. For optimizing photosynthesis various approaches and processes need to be improvised such as light harvesting complexes, reaction centres, carbon fixation and metabolic pathways for enhancing their photosynthetic efficiencies. This review highlights enormous potential and possibility of solar energy utilization leading to a new horizon to the researchers for exploring the CO2 sequestration by hybrid integrative photosynthesis (CO2-SHIP) for a sustainable renewable production of energy components for multi-product biorefineries.
