The oxidase test is used for identification of gram negative bacteria. This is one of the widely used methods and more important. Washington, D. Introduction There are a series of biochemical tests which are useful for the identification of, particularly, the gram negative enteric rods. However, even as biochemical tests were being developed to differentiate among bacterial genera and species, other efforts were being made to decrease the amount of time that was required not only to obtain a positive test result but also to generate a correct identification. Introduction to Biochemical tests In the microbiology lab, biochemical test relays on enzymes which is glycoprotein or protein that act as catalyst by lowering the activation energy of certain biological reaction. Klebsiella pneumoniae is urea positive (blue color of the slope), metabolise glucose with production of gas (bubbles under a piece of glass -. This series of simultaneous tests is designed to identify Gram-negative bacilli from the family Enterobacteriaceae.
