Mannitol salt agar (MSA) only allows the growth of halophiles. Among the halophiles, mannitol fermenters release acid that turns the pH indicator yellow; mannitol nonfermenters leave the medium red. Onto MSA you inoculate a halophilic mannitol fermenter and a nonhalophilic mannitol nonfermenter.  You see growth on only one of the plates. Given this scenario, the MSA acts as a _____ medium.
