MYP Agar 500g
Login to see pricesBrand:
Thermo ScientificTM OxoidTM
Selectively enumerate Bacillus cereus in food samples with Thermo Scientific™ Oxoid™ MYP Agar (Dehydrated). The medium relies upon mannitol fermentation and phospholipase C production to differentiate Bacillus cereus from other members of the species.
Mannitol-negative Bacillus cereus form pink colored colonies due to the presence of Phenol Red Indicator. Egg yolk emulsion helps in the differentiation of phospholipase C producing colonies, which are surrounded by a zone of the white precipitate. Polymixin B Sulphate acts as the inhibitor to restrict the growth of Gram-negative bacteria.

Description
CAS number: 142-82-5
Chemical Formula: CH₃(CH₂)₅CH₃
Molar Mass: 100.2 g/mol
Synonyms: n-Heptane
With their high degree of UV transmittance, low particle count, low acidity and alkalinity and low evaporation residue level, LiChrosolv® solvents are ideal for reproducible separations. Since separations are normally carried out under gradient conditions in analytical HPLC, we offer solvents in “gradient grade” as well as “isocratic grade”. This enables to minimize the gradient effect of the solvent involved. Filtered by 0.2 µm filter
