Rainbow® Agar O157 (Dehydrated Media)
Chromogenic Media for Microbial Detection Less than 24 Hours
Rainbow Agar O157 has both selective and chromogenic properties that make it particularly useful for isolating pathogenic E. coli strains. The medium contains chromogenic substrates that are specific for two E. coli-associated enzymes: ßgalactosidase (a blue-black chromogenic substrate) and ß-glucuronidase (a red chromogenic substrate).
Rainbow Agar O157 is listed in FDA's Bacteriological Analytical Manual (BAM) and presents the agency's preferred laboratory procedures for microbiological analyses of foods and cosmetics.
