General description
Scientifically proven supplement for culture media improves detection of Salmonella, Enterobacter sakazakii and Yersinia enterocolitica .
Ferrioxamine E from Streptomyces antibioticum is a siderophore which facilitates the supply of iron (III), an essential trace element, to bacteria involved in food poisoning, including Salmonella, Enterobacter saka-zakii and Yersinia enterocolitica. It promotes rapid growth by reducing the lag phase in culture media and reactivates dormant bacteria. Use of ferrioxamine E can permit rapid detection of low bacterial cell counts, even from dry products like spices and tea after long storage periods. It is an essential component of quality control efforts in the food industry.
Ferrioxamine E is often used in Buffered Peptone Water, the medium recommended by the ISO-Norms for Enterobacteriacea. Ferrioxamine E also improves the motility of Salmonella, which helps to improve the identification by semisolid selective motility media like SIM, MRSV, DIASSALM or SMS. Ferrioxamine E does not improve growth of Escherichia coli, Shigella, Proteus, Providencia and Morganella species; a feature that makes it a semi-selective compound. The recommended concentration of Ferrioxamine E to promote bacterial growth is between 5 and 200 ng/mL

The ferrioxamines are basically metabolic products produced by the actinomycetes, and are characterised as ferrioxamines A, B, C, D 1, D2, E, F and G. Generally all ferrioxamines are trihydroxamates and the deferrioxamines are either linear or cyclic (D2 and E).

Supplementation of buffered peptone water with ferrioxamine E in concentrations ranging from 0.001 to 1.0 microgram/ml significantly increased the motility of Salmonella on MSRV and DIASSALM semi-solid enrichment media. Zone diameters of swarming S. enteritidis and S. typhimurium increased more

Under iron limitation, the Gram-positive bacterium Streptomyces coelicolor A3(2) excretes three siderophores of the hydroxamate type: desferrioxamine B, desferrioxamine E, and coelichelin. These sequester iron from insoluble ferric hydroxides, and the resulting ferric complexes are believed to be transported into

Utilization of ferrioxamines as sole sources of iron distinguishes Salmonella enterica serotypes Typhimurium and Enteritidis from a number of related species, including Escherichia coli. Ferrioxamine supplements have therefore been used in preenrichment and selection media to increase the bacterial growth
