Biosequestration of carbon dioxide, biomass, calorific value and biodiesel precursors production using a novel flask culture photobioreactor

Abstract

Renewable, carbon neutral, economically viable alternative fuels are urgently needed to turn away the consequences of climate change Photosynthetic capability of microalgae with respect to CO₂ fixation at various CO₂ partial pressures generated by CO₂ generating buffer (KHCO₃/K₂CO₃), increases in biodiesel precursors using IR-CO₂ sensor and modern LED lights-based modern two tier flask photobioreactor has been studied Chlorella vulgaris and Scenesdesmus obliquus were found to produce 37.11% and 32.23% of palmitic acid (C16:0) and 30.88% and 39.73% of octadecenoic acid (C18:1) of total fatty acid methyl esters (FAMEs) respectively at 7.5% of CO₂ partial pressure, under the optimal values for growth Carbon dioxide fixation rate, efficiency of conversion of biomass to calorific value and biodiesel precursors were also estimated.
