Catalase test 🧪 ✔️The catalase test is a quick and easy method for differentiation of Streptococcus and Staphylococcus. ✔️All Streptococcus species are catalase negative and Staphylococcus are catalase positive (bubble production). ✔️The medium used must NOT have blood incorporated since the erythrocytes have catalase activity and can give false positive results. ✔️The test should be done on young cultures 18-24 hours. ✔️The reagent used is 3% hydrogen peroxide. . . #microbiologist #labtech #me

The catalase test is a simple and fundamental biochemical assay used in microbiology to differentiate between types of microorganisms, specifically bacteria. It determines whether a microorganism produces the enzyme catalase. ​🧪 The Science Behind It ​The purpose of the catalase enzyme is to protect the cell from toxic byproducts of aerobic respiration. When a cell uses oxygen, it inevitably produces reactive oxygen species (ROS), a common one being hydrogen peroxide (H_2O_2). Hydrogen peroxide
