Product details



Ammonium iron(III) citrate solution 12,5 %, sterile, ready-to-use
Directions for use

Ammonium iron (III) citrate (ferric ammonium (III) citrate) is used as additive in nutrient media for detection of Listeria species. Hydrolysis of esculin by Listeria species results in 6,7-dihydroxycoumarin which reacts with ferric ions producing blackening of the medium. Additionally, ferric ammonium citrate has been shown to improve the growth of Listeria monocytogenes (Cowart and Foster (1985) J. Infect. Dis. 151:721).


One box of 10 vials Ammonium iron(III) citrate solution is sufficient for 10 x 500 ml Fraser Broth (Art. No. HP17) or Fraser Half Broth (Art. No. HP18).
