BD™ Mannitol Salt Agar Plates

Mannitol Salt Agar is a formulation devised by Chapman for the differentiation of coagulase positive staphylococci (e.g., Staphylococcus aureus) from coagulase negative staphylococci.

• Used for isolating staphylococci from clinical specimens, from cosmetics, and in microbial limit tests.
• Contains peptones and beef extract, which supply essential nutrients.
• The 7.5% concentration of sodium chloride results in the partial or complete inhibition of bacterial organisms other than staphylococci.
• Mannitol fermentation, as indicated by a change in the phenol red indicator, aids in the differentiation of staphylococcal species.
• Positive staphylococci produce yellow colonies and a yellow medium; negative staphylococci produce red colonies and no colour change of the indicator.

Supplied in ready to use Stacker™ plates

• Prepared plated media are ready for immediate use
• Microbiologically controlled for uncompromised isolation of microorganisms
