CHALLENGE QUESTION You are given an unknown bacterium to identify. You do some initial testing and determine that the bacterium is a Gram-negative, motile rod with no unique colony morphology or pigmentation when grown on an agar plate. Given the following metabolic profiles for six known Gram-negative rods, create a dichotomous key which will guide the testing of your unknown bacterium. List all of the tests that you will need to run. (You should not have to run every single one.)
