Mannitol salt agar (MSA) only allows the growth of halophiles. Among the halophiles, mannitol fermenters release acid that turns the pH indicator yellow; mannitol non-fermenters leave the medium red. Onto MSA you inoculate a halophilic mannitol non-fermenter and a non-halophilic mannitol non-fermenter. What are your expected results in this experiment? Explain the role of the media in this case.
