I just did a \"use of selective and differential media lab\" andone of the questions is \"In what way are the media used in thisinvestigation selective and differential\"? I am not quite sure whatI am supposed to put here. During the lab, I used E. Coli, M.luteus, and S. epidermis. All of these microorganisms were spreadonto 3 plates. Mannitol salt, Eosin methylene blue, and MacConkeyagar plates.
