Additional Information
Ferric Ammonium Citrate Supplement (X211) or Fraser broth base supplement (7984) may be usedTechnology
Lithium chloride suppresses the growth of Enterococci in the medium, as Enterococci can also hydrolyze esculin also. Enzymatic digest of animal tissues, casein, meat extract and yeast extract provide the essential vitamins, minerals, amino acids, nitrogen and carbon, while sodium chloride maintains the osmotic balance. The selective components acriflavine and nalidixic acid are blended into the base powder and inhibit the growth of Escherichia coli. Ferric ammonium citrate is added to the tempered broth after sterilization. According to ISO 11290-1:2017, the test portion is inoculated into the primary enrichment medium Half Fraser (Demi-Fraser) Broth (ISO), followed by secondary enrichment in Fraser Broth (ISO) and then sub-cultured onto Harlequin Listeria Chromogenic Agar according to Ottaviani & Agosti (NCM1004). The medium conforms to the performance and formulation requirements of ISO 11290-1:2017.
