In this research, protein was used to consider the mechanism of surfactant adsorption on a single bubble interface. In order to change the property of a bubble interface, protein was added in purified water, and the bubble motion was visualized using a high-speed video camera. Trajectories, bubbles velocity and aspect ratios of the bubbles were calculated. In the protein solution, the single bubbles showed the motion similar to that observed in a solution of surface active surfactant such as 1-pentanol; attenuation in the high frequency shape deformation, an increase in the aspect ratio, a decrease in vertical velocity, and an increase in horizontal velocity. From these results, it was considered that protein molecules were absorbed on a bubble interface, and played a role similar to surface-active surfactant.
