Product Code TM 1915
MacConkey Sorbitol Agar Base is recommended for the isolation and identification of enteropathogenic Escherichia coli strains. It is based on the formulation described by Rappaport and Henigh which was modified by the ISO Committee. In this medium, E.coli O157: H7 is detected on the basis of its inability to ferment sorbitol, thus growing as colourless colonies.
