Catalase Test Purpose

Catalase test purpose. What is a catalase. A catalase test is one of the laboratory procedures used to identify a particular strain of bacteria. The morphologically similar enterococcus or streptococcus catalase negative and staphylococcus catalase positive can be differentiated using the catalase test. It is an enzyme produced by organisms that thrive in an oxygenated environment.

The test can aid in the identification and differentiation of different microorganisms. Using a sterile wooden stick or a glass rod take several colonies of the 18 to 24 hours test organism and immerse in the hydrogen peroxide solution. Catalase test can be used as an aid to the identification of enterobacteriaceae. Purpose used to differentiate bacteria that produce catalase from non catalase producing bacteria.

Observe for immediate bubbling. A semiquantitative catalase test is used for the identification of mycobacterium tuberculosis. Please describe the purpose of the catalase test. Its purpose is to neutralize toxic forms of oxygen metabolites.

Catalase test is used to differentiate aerotolerant strains of clostridium which are catalase negative from bacillus species which are positive. Purpose of catalase test catalase test is done to determine the presence of catalase in microorganisms. Catalase is a common enzyme which can befound in all living beings that survive in oxygenated condition catalyzes the breakageof hydrogen perox view the full answer.
