One Kligers slant with unknown bacteria inoculated and one control slant should be prepared.
Because while proceeding with the Dichotomous key, we start from the top. We will test for indole results. From the indole result, we may proceed either with Esculin or Glucose. From the result of esculin or glucose, we will proceed with (Kligers or Lactose) OR (Kilgers or Raffinose).
Working with dichotomous key is like you start with a question and with the results you proceed with the next question.

You are given a mixed culture of two organisms in a small tube of TSB.
You are given a mixed culture of two organisms in a small tube of TSB. These two organisms include a Gram-negative strain (your bacterial strain to identify) and a Gram-positive strain (a contaminant). Your first task is to isolate these organisms which will help you identify which Gram-negative strain you are working with. 1) You inoculate two streak plates on TSA media and MacConkey Agar using aseptic technique. For each medium, state whether the medium is selective, differential, or neither and...
