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...

Gram negative bacteria that can ferment glucose and/ or lactose, O c. Only those bacilli that can utilize citrate as a main carbohydrate source. O d. All Bacteria would grow equally well A bacterial species grows on a MacConkey agar plate, and the colonies have dark red color with hazy...
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?
Why would an agar plate contain a buffer? Look up a growth curve for organisms grown on agar in your text. Why does an organism enter the stationary phase of growth?
