分析報告

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.
