E. Catalase Activity. Catalase is the name of an enzyme found in most bacteria which initiates the breakdown of hydrogen peroxide (H2O2) into water and free oxygen. 1  If the bacterium produces the enzyme catalase, then the hydrogen peroxide added to the culture will be broken down into water and free oxygen. If the bacterium produces the enzyme catalase, then the hydrogen peroxide added to the culture will be broken down into water and free oxygen. 2  The oxygen will bubble through the water causing a surface froth to form. 3  This is a catalase-positive bacterium (see fig.
