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...

1. Apple tells his friends that he has recorded the colony morphology of his unknown by looking at the negative stain and Gram stain results, and the cell morphology from his streak for isolation on a Nutrient Agar plate. If you were Apple’s friends, how would you respond to Apple? 2. Helicobacter pylori, an organism that can live in the human stomach and cause ulcers, is urease positive. Why would that be an advantage to the organism?

2. You are given a mixed broth culture of Pseudomonas fluorescence (Gram-negative) and Clostridium sporogenes (Gram-positive). You are instructed to isolate and purify each bacterial species. How are you going to do it? Your goal is to have a plate of pure P. fluorescence with isolated colonies and a plate of pure C. sporogenes with isolated colonies. Explain in detail how you are going to perform the exercise. You can use any media you like such as nutrient agar plate,...
