024020P1 Mannitol Salt Agar(Granular Culture Media)
Usage:
For selective isolation and culture of Staphylococcus aureus.
Principle:
Peptone and beef extract powder provides carbon, nitrogen, vitamins and minerals; D- mannitol to fermentable sugars; higher levels of sodium chloride to provide a higher osmotic pressure, suppress most non-staphylococcal microorganisms ; phenolsulfonphthalein as pH indicator; agar is medium coagulant. Typical pathogenic staphylococci (coagulase positive) D- mannitol produce acid fermentation and produce yellow colonies with a yellow halo, typically non-pathogenic Staphylococcus unfermented D- mannitol to form red colonies.
