MAST Mannitol Salt Agar – 500g

MAST Mannitol Salt Agar 500g is a selective and differential microbiological culture medium used primarily for the isolation and differentiation of Staphylococcus species, particularly Staphylococcus aureus. Its high sodium chloride concentration inhibits many competing organisms while allowing salt-tolerant staphylococci to grow. Mannitol and a pH indicator allow differentiation based on mannitol fermentation. Staphylococcus aureus commonly ferments mannitol, producing acid and causing the surrounding medium to turn yellow. Key Features - Selective medium for Staphylococcus species - Particularly useful for presumptive identification of Staphylococcus aureus - High salt concentration suppresses many non-staphylococcal organisms - Differentiates organisms by mannitol fermentation - Suitable for clinical and food microbiology - Supplied as dehydrated powder - 500g pack - MAST product code DM160D Specification Details Product Name Mannitol Salt Agar Brand MAST Product Code DM160D Pack Size 500g Form Dehydrated powder Medium Type Selective and differential culture medium Main Target Organisms Staphylococcus spp. Key Target Organism Staphylococcus aureus Differentiation Principle Mannitol fermentation Selective Principle High sodium chloride concentration Indicator Phenol red Laboratory Area Microbiology Intended Use In vitro laboratory use
