Abstract: “Carbon dioxide is the major contributor to pollution build-up that can be circumvented if this carbon dioxide is captured and utilised for manufacturing of other products. In our present study, we aimed to cultivate the microalgae utilising renewable carbon source CO2. We observed a rapid growth of microalgae 0.91 day-1 for Nannochloropsis sp. and 0.5 day-1 for A. platensis in stirred batch closed photobioreactor. Also, the studies on CO2 sequestration rate by these microalgae revealed that A. platensis have 14.36% higher CO2 sequestration rate when grown in photobioreactor”
