Many aerobic bacteria and most of those which are facultatively anaerobic produce the enzyme catalase. The function of this enzyme is to detoxify hydrogenperoxide (H2O2), which is formed from the superoxide radical by superoxide dismutase. Many aerotolerant anaerobic bacteria have peroxidase (which is not the same enzyme as cytochrome c oxidase) instead of catalase. Obligate anaerobic bacteria lack superoxide dismutase and catalase.
The catalse test is primarily used for gram positive bacteria and can for instance be utilized to distinguish Staphylococcus spp. and Micrococcus spp., which are catalase positive from Streptococcus spp. and Enterococcus spp., respectively, which are catalase negative.
