S2 Media 15x100mm Bacillus cereus Mannitol Yolk Polymyxin (MYP) Agar, 10/pack
Bacillus cereus Mannitol Yolk Polymyxin (MYP) Agar is a selective and differential medium used for the to isolate and enumerate Bacillus cereus in foods. Mosel et al., formulated MYP Agar to isolate and enumerate Bacillus cereus from foods. Polymyxin inhibits normal microbial flora present in the sample. Bacteria that produce lecithinase hydrolyze the lecithin in the egg yolk. The insoluble products of egg yolk lecithin accumulate around the colonies to form a zone of white precipitate. Bacteria which ferment mannitol produce acid products and will form colonies that are yellow. Bacillus cereus is typically mannitol-negative (pink to red colonies) and lecithinase-positive (zone of precipitate around the colonies).• Product meets CLSI reference methods and performance criteria.• MYP Agar should be used by trained professionals within a laboratory setting. • Product is not intended for use in the diagnosis or treatment of disease or other human conditions.
