应用
ReadyPlate™ Mannitol Egg Yolk Polymyxin Agar is used for the confirmation ａnd enumeration of colonies of Bacillus cereus in food samples.
分析说明
The MYP agar differentiates B. cereus from other bacteria by its resistance to Polymyxin B, its inability to produce acids from mannitol, ａnd the presence of lecithinase. Peptone ａnd meat extract serve as carbon ａnd nitrogen sources for B. cereus. Bacteria that ferment mannitol to produce acids produce yellow staining of the medium with phenol red as a pH indicator. The lecithin present in egg yolk is cleaved by the lecithinase-producing B. cereus, leading to the formation of an opalescent white precipitation zone surrounding the colonies. Since B. cereus is mannitol-negative, the agar around colonies remains unchanged or is discolored by light alkalization (pink colonies). E. coli, other Enterobacteriaceae, ａnd P. aeruginosa are inhibited by Polymyxin B.
