Opis: Chromogenic media offer a method for rapid identification of characteristic bacterial enzymes. Merck offers a wide range of solid and liquid culture media that also permits the fluorescence detection of <i>E. coli</i> under the trade name Fluorocult®. Fluorocult® culture media have the same components as the standard media and additionally the substrate MUG. Some of the media also contain tryptophan as the substrate for a possible indole reaction to further confirm <i>E. coli</i> presence. The Fluorocult® method can produce a positive result within just 24 to 48 hours. In the case of the chromogenic media, a direct identification, using the characteristic colony colouring on the culture medium itself is possible without the application of further additives. A differentiation of positive single colonies is possible, even when high microbial counts are present.

Opis: Dehydrated media are used for a wide variety of applications. To minimise the risks associated with powdered culture media, the majority of Merck's dehydrated culture media is produced in granular form. Merck uses ingredients of non animal origin to minimise the potential risk of transmissible spongiform encephalitis (TSE). When there is no alternative, only ingredients which are recommended by EDQM, and belonging to TSE category B or C are used. This ensures that the product is of the highest quality and in compliance with the standards for food control, microbiological testing on finished products and starting materials, and quality control in the pharmaceuticals and cosmetics industries. Custom-made media can be prepared to meet individual customer specifications. The formulation is kept confidential via a Non Disclosure Agreement. Please enquire for further details.
