说明
一般描述
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).[1]
应用
在预增菌肉汤和增菌肉汤培养基中加入铁草氨菌素 E 显著改善了从人为或天然污染食品中对沙门氏菌的回收率。
