Product Description
Mannitol Salt Agar Plate (Lockable Plate) | MPH118L-20PT | Himedia is a ready-to-use microbiological culture medium designed for the selective isolation and presumptive identification of Staphylococcus species, particularly Staphylococcus aureus, from clinical, food, environmental, and other microbiological samples. The medium combines a high salt concentration with mannitol and a phenol red indicator to help differentiate microorganisms based on their ability to tolerate salt and ferment mannitol.
The high sodium chloride concentration makes Mannitol Salt Agar selective for salt-tolerant bacteria, especially members of the genus Staphylococcus. When mannitol is fermented, acid is produced, resulting in a change in the phenol red indicator and providing a useful visual differentiation between mannitol-fermenting and non-fermenting organisms. This makes the medium suitable for preliminary screening before further biochemical or confirmatory testing.
The MPH118L-20PT format is supplied as a pre-poured plate, reducing the preparation time and handling associated with conventional laboratory media preparation. The ready-to-use format can help maintain consistency between tests while minimizing the possibility of contamination during media preparation. The lockable plate design provides a practical solution for laboratories that require secure handling and storage of prepared culture plates.
Mannitol Salt Agar Plates can be used in microbiology laboratories, diagnostic laboratories, food and beverage testing facilities, pharmaceutical quality-control laboratories, educational institutions, and research environments. Typical applications include screening samples for salt-tolerant staphylococci, preliminary differentiation of S. aureus, and microbiological examination of various sample types.
For reliable results, samples should be inoculated and incubated according to the laboratory’s validated procedure and the manufacturer’s recommended instructions. Colony appearance and color changes should be interpreted together with appropriate controls and, where required, confirmed using additional identification methods.
The Himedia Mannitol Salt Agar Plate (Lockable Plate) offers a convenient combination of selective and differential properties in a ready-to-use format, supporting efficient routine microbiological screening and laboratory workflows.
FAQs
1. What is Mannitol Salt Agar Plate used for?
Mannitol Salt Agar Plate is primarily used for the selective isolation of salt-tolerant bacteria, particularly Staphylococcus species, and for the presumptive differentiation of mannitol-fermenting organisms such as Staphylococcus aureus.
2. How does Mannitol Salt Agar differentiate microorganisms?
The medium contains a high concentration of sodium chloride that inhibits many non-salt-tolerant bacteria. Mannitol fermentation produces acid, which changes the phenol red indicator and helps differentiate fermenting organisms from those that do not ferment mannitol.
3. What organism is commonly identified using Mannitol Salt Agar?
Staphylococcus aureus is commonly screened using Mannitol Salt Agar because it typically tolerates the high salt concentration and can ferment mannitol, producing an indicative color change around colonies.
4. Is this product ready to use?
Yes. The MPH118L-20PT product is supplied as a pre-poured culture plate, helping laboratories avoid the preparation, sterilization, and pouring steps required when preparing agar plates manually.
5. What is the benefit of the lockable plate design?
The lockable plate design provides convenient and secure handling of the prepared culture plate during laboratory workflows, storage, and transport within the laboratory environment.
