6.4: Dichotomous Key for Bacterial Unknowns

  • Page ID
  • Use the space below to draw your dichotomous key based on the staining and metabolic activity results you have obtained for the 10 organisms (see table at end of Lab 5). You will be using this key to identify your own two unknowns.

    Based on your dichotomous key, list the metabolic tests you will need to identify each of your unknowns, and the media that you will used for each test.

    Unknown A: Metabolic test required Unknown A: Media Unknown B: Metabolic test required Unknown B: Media
