  • Description

    Chromogenic Listeria Agar Base (Modified) is a selective media used for isolation, enumeration and presumptive identification of Listeria species and Listeria monocytogenes. It is a modification of original formulation of Notermans et al. (1991) and Mengaud et al. (1991). Listeria species grow over a pH range of 4.4 – 9.6 and survive in food products with pH levels outside these parameters. This media specifically selects Listeria spp. using a combination of chromogenic and fermentation reaction. Hydrolysis of chromogenic mixture and rhamnose fermentation easily differentiates L.monocytogenes (bluish-green colonies) from other Listeria species which are not able to ferment the carbohydrate.
