What differentiates aureus from ither Staphylococcus genera on the MSA plate? How do the two bacteria differ when growing on the media ?
Added by Andrea W.
Step 1
The key differentiating factor is the ability of S. aureus to ferment mannitol, which is present in the MSA plate. When S. aureus ferments mannitol, it produces acidic byproducts that lower the pH of the surrounding medium. This change in pH causes the phenol red Show more…
