Appearance
Dehydrated medium: Straw pink coloured, free-flowing powder
Prepared medium: Pink-red coloured gel
Storage conditions and Shelf life
Store the dehydrated medium at 10-30°C and use before the expiry date on the label.
Store the prepared medium at 2-8°C.
Technique
Inoculate the medium heavily with the specimen, spreading a portion of the original inoculum in order to obtain well separated colonies on some part of the plate. Incubate for 18 to 24 hours at 35°C; non-lactose fermenters form colourless colonies, whilst occasional resistant coliforms or other lactose fermenters produce pink or red colonies.
In parallel with the SS Agar plate, inoculate a tube of Selenite Broth CM0395 enrichment medium, incubate for 12 hours at 35°C, and sub-culture on to another SS Agar plate.
