Neogen® Mannitol Salt Agar, 500 g, Jar

Neogen Mannitol Salt Agar is an essential selective medium for isolating and identifying staphylococci, particularly Staphylococcus aureus, in the food processing industry. With a high salt concentration of 7.5% that inhibits most bacteria, this agar utilizes mannitol and phenol red for differentiation; pathogenic staphylococci ferment mannitol, producing yellow colonies, while non-pathogenic ones appear as small red colonies. This medium is crucial for microbiological quality control, ensuring food safety and compliance with health regulations, and is also used in microbial limit testing of food products and cosmetics, although further biochemical testing is required for definitive identification.
