The increase in CO2 emissions is a critical challenge that requires effective mitigation strategies. One of the promising approaches is by using microalgae as a CO2 capture agent. Microalgae can efficiently absorb CO2 and convert it into biomass which can be further processed as valuable added product. Among them, Euglena gracilis stands out due to its resilience in extreme conditions and strong CO2 fixation capabilities. In this project, we are studying the CO2 capture ability of Euglena gracilis and its mass transfer phenomenon, along with the effects of pH and light intensity on its growth kinetics in photobioreactors. Additionally, we aim to develop a model to understand how reactor scale influences CO2 mass transfer and its efficiency in large-scale applications. This study seeks to optimize cultivation conditions and improve CO2 capture efficiency for broader implementation.
