Description: Clean, fresh water is one of the most important issues facing humanity today. Also in the food and pharma industries the examination of water is prescribed. Granulated media from Merck are produced under strict guidelines and quality is controlled according to ISO 11133.

Supplier: Merck

Description: The isolation of microorganisms often requires the use of selective media. The use of freeze-dried supplements ensures an optimal and standardised medium preparation and thus optimised performance of the selective medium.

Supplier: Merck

Description: In combination with the selective supplement Lithium-Mupirocin (MUP) the TOS Propionate agar allows the direct detection of viable bifidobacteria in starter cultures and various milk products like fermented and unfermented milk, milk powder and baby food. The growth of other lactic acid bacteria is very much inhibited so that a confirmation of presumptive bifodobacteria is in most cases not necessary.

Description: Selective medium for the detection of <i>Enterobacter sakazakii</i> in milk powder and powdered infant formula. The base in Chromocult ® Enterobacter sakazakii agar allows good growth and strong colour formation of <i>E. sakazakii </i>colonies. The addition of inhibitors and the incubation temperature of 44 °C largely reduce the growth of the majority of gram-positive and gram-negative accompanying flora.<i> E. sakazakii</i>  is ß-D-glucosidase positive and grows as blue-green colonies on this medium. Incubation: 24 ±2 hours at 44 ±1 °C. Incubation temperature has a strong influence on sensitivity and selectivity of this method. Temperatures higher than 45 °C will inhibit the growth of <i>E.sakazakii.</i> Temperatures below 43 °C will reduce inhibition of accompanying bacteria.

Description: 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.

Catalog Number: (1.00427.0500)

Supplier: Merck

Description: This medium conforms to the ALOA (agar Listeria acc. to Ottaviani and Agosti) medium, a selective medium for the isolation of <i>Listeria monocytogenes</i> in food (AFNOR-validated method). It also enables the testing, sampling and enumeration of <i>Listeria monocytogenes</i> and Listeria spp. in foodstuffs and other source materials. The rich base of the Chromocult® Listeria selective agar encourages excellent growth. The supplement of inhibitors stops most of the bacteria, yeast and fungi from growing. In contrast, Listeria is uninhibited in its growth, producing blue-green colonies; <i>L. monocytogenes</i> also form an opaque halo.

Description: 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.
