Mannitol Salt Agar Powder

This 100g pack of Mannitol Salt Agar is a selective growth medium primarily used for isolating and differentiating Staphylococcus species, particularly S. aureus. The high salt concentration (7.5%) inhibits the growth of most other bacteria, while the inclusion of mannitol provides differentiation: S. aureus ferments mannitol and turns the agar yellow, while S. epidermidis does not and maintains the red color. Ideal for clinical, research, and diagnostic laboratories performing bacterial identification. For laboratory use only.
