Catalase Test: Procedure, Significance, and Bacterial Identification Made Easy

Introduction The Catalase Test is a rapid and efficient diagnostic tool for identifying bacterial species. By detecting the presence of the enzyme catalase, this test distinguishes catalase-positive bacteria, like Staphylococcus, from catalase-negative organisms, such as Streptococcus. Widely used in clinical microbiology, it provides valuable insights for bacterial identification. Catalase is …
