Descripción general
GranuCult® XLT4 agar (Base) contains a selection of suitable nutrients and vitamins (peptones, yeast extract) that allow optimal growth of salmonellae. The surfactant NIAPROOF-4 (formerly Tergitol-4/Sodiumtetradecylsulfate) inhibits the accompanying flora. Salmonellae, due to H2S-formation (thiosulfate and iron (III)-ions), can be easily detected as black colonies on a red-violet background and differentiated from the residual accompanying flora. E. coli shows yellow colonies on a yellow background due to acidification of the medium (pH-indicator: phenol-red). Other accompanying organisms, like Shigella, will grow colorless on a red background due to a missing H2S-formation and acidification.
Aplicación
GranuCult® XLT4 agar (Base) is suitable for the isolation and identification of pathogenic Enterobacteriaceae, especially Salmonella spp.
