"Mannitol Salt Agar (MSA)" is a differential medium because it has sugar mannitol and the 'pH indicator' phenol red. If an organism ferments mannitol and produce acid the colour of the indicator will turn to yellow.
Yeast and Mold (YM) is low pH differential media which deters the bacterial growth.
