Catalase Reagent Droppers are used in a qualitative procedure for determining catalase activity by bacteria.
The enzyme catalase is preset in most aerobic and facultatively anaerobic bacteria, with the major exception of streptococci and enterococci. The enzyme catalase decomposes hydrogen peroxide into water and oxygen.
Catalase Reagent Droppers contain a hydrogen peroxide solution of approximately 3% (2.5% to 3.5%). This reagent has been frequently cited as a standard method for performing the catalase test.
