The relationship between the periodical bubble forming and the oscillatory change in the dissolved oxygen (DO) concentration in a catalase-hydrogen peroxide system was studied. Photographs of the bubbles and the responses from the DO electrode indicated that large bubbles were generated periodically, and that the DO profile depended on the geometrical relationship between the electrode and the bubbles.
