Selenite-Cystine Broth
Selenite-Cystine broth is used for the selective enrichment of Salmonella in milk and dairy products but also for the characterization of residual sludge It can also be used in animal health for the detection of Salmonella Gallinarum or in water testing.
The typical composition responds to that defined in the standards NF U47-101 & NF U47-102; NF EN ISO 6579-1/A1; NF EN ISO 19250; FD/CEN/TR 15215-2.
Available as dehydrated medium : 500 g bottle
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.
The quantity of selenite inhibits microorganisms other than salmonellae, especially coliform bacteria and enterococci. Pseudomonas and Proteus are partially inhibited.
Dipotassium phosphate maintains the pH constant and reduces the toxicity of selenium in order to increase the recovery capacity of the medium.
