    Escherichia coli (E. coli) is catalase positive. Catalase is an enzyme that helps break down hydrogen peroxide into water and oxygen. When hydrogen peroxide is added to a bacterial culture, catalase-positive bacteria like E. coli produce bubbles of oxygen gas due to the catalytic action of the enzyme. This is a characteristic biochemical test used to differentiate between different bacterial species based on their enzyme activity.
