Catalase is an enzyme, which is produced by microorganisms living in the environment to neutralize oxidative toxic forms of oxygen metabolites; H2O2. The catalase enzyme neutralizes bactericidal action of hydrogen peroxide and protect them. Anaerobic bacteria lacking the enzyme catalase normally.
Catalase mediated decomposition of H2O2 into oxygen and hydrogen peroxide water. To find out whether a particular strain of bacteria can produce the enzyme catalase, small composition of bacteria isolated were mixed in a solution of hydrogen peroxide (3%) and rapid construction of gas bubbles occur. The lack of catalase is evident by a lack or weak manufacturing bubble
