Alkali Scientific Mannitol Salt Agar, 1 Kg
Supplier: Alkali Scientific MAN001CP
Mannitol Salt Agar (MSA) is a selective culture medium used for the isolation of Gram-positive microorganisms, especially staphylococci, from various samples. The 1kg format provides a large supply of the medium, ideal for labs conducting microbiological testing, particularly in food safety, clinical diagnostics, and environmental monitoring. The high salt concentration (7.5%) inhibits the growth of most bacteria except for salt-tolerant organisms. Additionally, the mannitol in the medium serves as a fermentable carbohydrate, and the phenol red indicator changes color to yellow when mannitol is fermented, providing a visual cue for identifying pathogenic strains.
