Respuesta :
Gram positive bacteria are identified using biochemical tests such as the catalase test, the coagulase test, the starch hydrolysis test, and the nitrate test, whereas Gram negative bacteria are identified using biochemical tests such as the oxidase test, the urease test, the indole test, the sulphur test, and the methyl red/voges-proskauer test.
Why is the Gram stain such an effective diagnostic tool?
