Medium reagent Dry SL

for microbiologysucroseSalmonella

READY AND EASY TO USE PORTABLE PLATE: PREPARATION OF MEDIUM IS NOT REQUIRED, WHICH ELIMINATES WASTE OF MEDIUM AS WELL AS STERILIZING APPARATUS TO PREPARE THE MEDIUM. DETECTION OF COLONIES ON PLATE IS SIMPLE AND CLEAR. SINGLE COLONIES ON THE PLATE CAN BE ISOLATED FOR FURTHER IDENTIFICATION TESTS DESCRIPTION Compact Dry SL detects salmonella using 20 – 24 hour pre-enrichment cultures. The plates are based on the combination of three different test principles: 1. Alkalization of the medium, by Salmonella´s lysine decarboxylase ability (the medium colour will change from blue-purple to yellow) 2. Greening of the colony, caused by decomposition of chromogenic substrate with a specific enzyme of Salmonella (black colonies are generated by hydrogen sulphide producing Salmonella) 3. The motility of Salmonella Additionally, the colonies isolated from Compact Dry SL can be used for confirmation of Salmonella. Coliforms generate color change from blue-purple to red-purple by fermented lactose and/or sucrose in the medium. Please follow this operating procedure precisely, especially how to inoculate sample and sterilized water, to exploit the specific advantages of Compact Dry SL.
