The development of an efficient CO2 capture technology will reduce anthropogenic carbon dioxide emissions. Microalgae CO2 capture may be a potential approach to reduce carbon release of industrial plants. However, the CO2 concentrations of industrial releases are so high that they can constrain the growth rate of most microalgae. This study investigated the key scientific issues of carbon dioxide capture process: screening high CO2 tolerant microalgae and its corresponding CO2 conversion mechanisms. A 136 days of continuous transfer procedure is developed to select a tolerant microalgae species with CO2 enrichment. Under the stress of the high concentrations of carbon dioxide, the microalgae transferred the genetic information for the resistance to carbon dioxide to its offsprings. Genetic information of the resistance was highlighted and maintained through generations during the continuous transfers.The CO 2 capture ability of the developed microalgae species is verified in the typical microalgae photo-reactors: the closed gas bag system and bubble column reactors. Desmodesmus armatus was selected as the model species to study the detailed molecular information for a tolerant species' cellular physiology adjustment to the high concentrations of CO2. A total of 432 metabolic molecules were collected from the microalgae with ambient (0.04% CO2) and elevated (15% CO2) treatments, 37 of which occurred at significantly different concentrations. The identified metabolites were related to enhancing the cellular physiology mechanisms of the microalgae to thrive in the very high concentration CO2. Through this study, we examine how CO2 enrichment can improve the productivity of microalgae for industrial applications. Besides, a mechanistic kinetic model was developed to study the RubisCO, the enzyme that controls the rate limit step of carbon fixation. The catalytic details of RubisCO were explained through the model.
