CAD$96.80

PALCAM Agar is a selective medium used for the differentiation and isolation of Listeria monocytogenes and other Listeria, from milk and cheese, as well as in other food products, even highly contaminated.

The media can be used as a second media of choice in the context of the directives concerning the detection of Listeria monocytogenes in food microbiology (NF EN ISO 11290-1).

PALCAM agar can also be used as a confirmation test for Listeria spp using the COMPASS® Listeria method.

Available in 500g container, to be used with the following supplements:BS00408 (PALCAM Selective Supplement, 10 vials qsp 500 ml) or BS04908 (8 vials qsp 2,5 L).

Also available in ready-to-use medium: 20 Petri plates Ø 90 mm (BM02008).

In compliance with regulatory requirements, a USDA permit (VS 16-3) is mandatory for shipments from Canada to the USA due to the inclusion of peptone, an animal byproduct.

QUANTITY

Peptones and yeast extract favor the excellent growth of Listeria.
Glucose and starch are the energy sources for microbial development.
Sodium chloride maintains osmotic balance.
Listeria hydrolyze esculin to glucose and esculetin, the latter compound forming a black complex with ferric ions supplied by ferric citrate.
Accompanying microflora are inhibited by lithium chloride, ceftazidim, polymyxin and acriflavin.

The fermentation of mannitol by contaminating bacteria that may grow causes phenol red to turn yellow, thereby orienting the diagnosis.
