Research Abstract	Recently, a raise of carbon dioxide gas causes various problems such as warming of the earth, acidification of seawater, etc. The objective of this study is to develop a carbon dioxide sequestration and oxygen generating system using a plant-like cell assembly technology. In this study, a three-dimensional cell assembly and culturing technique was developed based on alginate-beads cell culture. Using our technique, the rate of oxygen generation increased 5-10 times larger than that of cell suspension culture. Moreover, the process of oxygen generation and carbon dioxide sequestration was retained continuously for 6 hours.
