Beschreibung

Allgemeine Beschreibung

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).

Anwendung

Der Zusatz von Ferrioxamin E in Voranreicherungsbouillons und Anreicherungsbouillons erhöht die Wiederfindungsrate von Salmonellen aus natürlich und unnatürlich kontaminierten Nahrungsmitteln signifikant.
