If an unknown gram-positive bacterium was given, what would it mean if it grew on MSA? Name the organisms used above My answer: that it would be either s.aureus or s. epidermis because they are selective for salt-tolerant bacteria and can grow on mannitol 2. what would it mean if it both grew on MSA and turned yellow?
