Description
Use RAPID'E.coli 2 Agar for the identification and enumeration of generic E. coli and other coliforms in products intended for human or animal consumption, or in environmental samples. RAPID'E.coli 2 Medium uses two chromogenic color reactions, β-D-galactosidase (GAL) and β-D-glucuronidase (GLUC), for the clear identification of E. coli and other coliforms.
Features and Benefits
- Direct enumeration of E. coli and coliforms on a single plate
- Coliforms are GAL+/GLUC- and form blue to green colonies
- E. coli is GAL+/GLUC+ and forms violet to pink colonies
- Results in 24 hr
Note: There are a few β-D-glucuronidase-negative strains of E. coli, e.g., E. coli O157. Some serovars of Salmonella and a few species of Shigella possess the enzyme β-D glucuronidase (< 1.5%).
