CAD$124.22

Giolitti and Cantoni Broth with Tween 80 is a selective enrichment medium for the detection and enumeration (particularly in low numbers) of coagulase positive staphylococci in food products. The media is used with the MPN method.

The typical composition corresponds to that defined in the standard NF EN ISO 6888-3.

Available in the following formats:

Ready-to-use dehydrated medium (without potassium tellurite): 500 g bottle

Also available as ready-to-use medium (without potassium tellurite):
50 tubes of 10 ml (single strength media) (BM11008).
50 tubes of 10 ml (double strength media) (BM11108).

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

Pyruvate, glycine and especially mannitol favor the development of staphylococci.
Gram-negative bacteria are inhibited by lithium chloride.
Gram-positive strains are inhibited by the action of potassium tellurite.

The anaerobic environment suppresses the growth of micrococci.
Tween 80 acts as a dispersion agent.
The development of staphylococci is shown by the appearance of a black color due to the reduction of tellurite to metallic tellurium.
