Sorbitol MacConkey Agar

PP0250

This is a differential medium for the isolation of Escherichia coli O157:H7. It differs from other MacConkey media in that lactose has been replaced by sorbitol. As Escherichia coli O157:H7 does not ferment sorbitol, it produces pale translucent colonies whereas most other strains of Escherichia coli do ferment sorbitol and produce pink colonies.
