1. Introduction

Among the atmospheric pollutants, CO2 contributes significantly to the greenhouse effect. Global warming attributed primarily to the elevated CO2 level in the atmosphere has led to various CO2 mitigation strategies. As chemical reaction based CO2 capturing is relatively costly and energy consuming, it is necessary to develop cost effective and sustainable alternatives. Biological CO2 mitigation leads to the production of biomass energy and is an alternative strategy of CO2 fixation through photosynthesis (Kondili and Kaldellis, 2007; de Morais and Costa, 2007). Microalgae are more efficient than terrestrial plants in photosynthesis from ambient air and are important for the prevention of increase in atmospheric CO2 concentration. It converts CO2 into biomass energy and thus recycles CO2 (Demirbas, 2004). Coupling of CO2 sequestration with algal cultivation reduces the carbon footprint and sustainable environment. Microalgae have drawn more attention as a promising source for the production of biodiesel because they possess high growth rate and provide lipid fraction for biofuel production. Microalgal growth and biochemical composition are governed by environmental conditions (Guiheneuf et al., 2008; Pal et al., 2011). Sodium bicarbonate has been demonstrated to enhance lipid accumulation in both freshwater and marine microalgae (Gardner et al., 2012, 2013; White et al., 2013; Peng et al., 2014). Microalgae utilize bicarbonate as the external source of carbon for photosynthesis and derive CO2 via the action of carbonic anhydrase (Dixon et al., 1987; Nimer et al., 1997; Bozzo et al., 2000). This work established the growth of Chlorella vulgaris in a medium where sodium bicarbonate serves as a source of inorganic carbon by assessing growth rate, chlorophyll content, biomass and lipid production in batch cultures. Further, rates of inorganic carbon concentration and CO2 fixation were determined for CO2 sequestration using bicarbonate.
