Ferrioxamine E is a bacterial siderophore produced by a variety of bacteria including S. glaucescens, M. luteus, and P. mendocina. Ferrioxamines, including ferrioxamine E, are the sole iron source for Salmonella, and have been used as growth enriching agents in the detection of Salmonella in food and industrial applications.

Ferrioxamine E-supplemented pre-enrichment and enrichment media improve various isolation methods for Salmonella
Int J Food Microbiol 1996 Feb;29(1):81-91.PMID:8722189DOI:10.1016/0168-1605(95)00024-0.
Supplementation of pre-enrichment broth and enrichment broth media with Ferrioxamine E (1 microgram/ml) significantly improved the recovery of Salmonella from artificially or naturally contaminated foods. Based on the selectivity of Ferrioxamine E, Salmonella enteritidis and S. typhimurium could be isolated also from various mixed cultures (one Salmonella cell in 10(3)-10(4)-fold concentration of cells of competitors) by shaking for 6 h in supplemented buffered peptone water followed by cultivation on XLD- or XLT-4 agars. Isolation of Salmonella from these pre-enrichment cultures by use of Dynabeads-Anti-Salmonella was highly effective. 27 S. typhimurium strains were isolated from 762 naturally infected chicken giblets by use of unsupplemented Tetrathionate broth. However, 33 S. typhimurium isolates were obtained with ferrioxamine E-supplemented Tetrathionate broth from the same samples. Three Salmonella isolates out of 50 evenly divided meat meal samples were obtained by use of ferrioxamine E-supplemented buffered peptone water followed by direct streaking onto XLD- and Rambach agars, no Salmonella isolates could be detected by the conventional method.
Characterization of Ferrioxamine E as the principal siderophore of Erwinia herbicola (Enterobacter agglomerans)
Biol Met 1988;1(1):51-6.PMID:2978958DOI:10.1007/BF01128017.
Several strains of the enterobacterial group Erwinia herbicola (Enterobacter agglomerans) were screened for siderophore production. After 3 days of growth in a low-iron medium, all strains studied produced hydroxamate siderophores. The retention values of the main siderophore during thin-layer chromatography on silica gel plates and on HPLC reversed-phase columns were identical with those of an authentic sample of Ferrioxamine E (norcardamine). Gas-chromatographic analysis of the HI hydrolyzate yielded succinic acid and 1,5-diaminopentane in equimolar amounts; fast-atom-bombardment (FAB) mass spectroscopy showed a molecular mass of 653 Da. Iron from 55Fe-labelled Ferrioxamine E was well taken up by iron-starved cells of E. herbicola (Km = 0.1 microM, Vmax = 8 pmol mg-1 min-1). However, besides Ferrioxamine E (100%), several exogenous siderophores such as enterobactin (94.5%), ferric citrate (78.5%), coprogen (63.5%) and ferrichrome (17.5%) served as siderophores, suggesting the presence of multiple siderophore receptors in the outer membrane of E. herbicola.
Optimization of Ferrioxamine E concentration as effective supplementation for selective isolation of Salmonella enteritidis in egg white
J Food Prot 2006 Mar;69(3):634-8.PMID:16541696DOI:10.4315/0362-028x-69.3.634.
Utilization of Ferrioxamine E (FE) as a sole source of iron distinguishes Salmonella from a number of related species, including Escherichia coli. FE is not able to serve as a source of iron for E. coli or the Proteus-Providencia-Morganella group. This confers a selective advantage on Salmonella Enteritidis in egg white supplemented with FE. The optimum concentration of FE that promoted a selective advantage for Salmonella in egg white was determined. Four supplementation concentrations were evaluated (25, 50, 200, and 500 microg/ml) in egg white artificially inoculated with proportionally mixed cultures of a rifampin-resistant strain of Salmonella Enteritidis (0.1 ml of 102 CFU/ml) and E. coli K-12 (0.1 ml of 10(1) through 10(8) CFU/ml). After a 24-h incubation at 37 degrees C, Salmonella and E. coli populations were enumerated. At higher concentrations of FE (>50 microg/ml), both Salmonella and E. coli were able to use the iron supplement (1 to 8.5 log CFU/ml and 1.8 to 8 log CFU/ml, respectively); however, lower FE concentrations (< or = 50 microg/ml) exclusively promoted Salmonella growth. Salmonella was unrecoverable without supplementation. This study indicates that optimum levels of FE supplementation in egg can improve the selective detection for Salmonella Enteritidis among other competitive organisms.
Studies on the redox characteristics of Ferrioxamine E
Chem Biodivers 2010 Mar;7(3):656-65.PMID:20232334DOI:10.1002/cbdv.200900031.
Thermodynamic parameters for the reduction of Ferrioxamine E as calculated from redox potentials determined at four different temperatures were found to be DeltaH( not equal)=7.1+/-3.4 kJ mol(-1) and DeltaS( not equal)=-146 J mol(-1) K(-1). The negative entropy value is large, because the decrease in the charge at the metal center and an increase in its ionic radius force the structure of the complex to become less rigid and resemble the desferrisiderophore. The hydrophilic groups of the system are now (relatively more) available for solvent interaction. Thus, a large negative entropy change accompanies the reduction of the complex. Kinetics of reduction of ferrioxamine by V(II), Cr(II), Eu(II), and dithionite were measured at different temperatures and by dithionite at different pH values. The Cr(II) and Eu(II) reactions proceed by an inner-sphere mechanism and have second-order rate constants at 25 degrees of 1.37x10(4) and 1.23x10(5) M(-1) s(-1), respectively. For the V(II) reduction, the corresponding rate constant was 1.89x10(3) M(-1) s(-1). The activation parameters for the V(II) reduction were DeltaH( not equal) = 8.3 kJ mol(-1); DeltaS( not equal) =-154 J mol(-1) K(-1). These values are indicative of an outer-sphere mechanism for V(II) reduction. The reduction by dithionite is half order in dithionite concentration indicating that SO(2)(-*) is the sole reducing species. log of reduction rate constants of different trihydroxamates by this reductant were correlated with their respective redox potentials, and the variation was found to be in approximate correspondence with the expectations of Marcus relationship.
Resuscitation by Ferrioxamine E of stressed Salmonella enterica serovar typhimurium from soil and water microcosms
Appl Environ Microbiol 2000 Sep;66(9):4128-30.PMID:10966440DOI:10.1128/AEM.66.9.4128-4130.2000.
Storage of Salmonella enterica serovar Typhimurium strains in soil and water microcosms resulted in loss of culturability on standard plating media. Prior incubation in buffered peptone water supplemented with Ferrioxamine E markedly extended the time that bacteria were recoverable by plating, except in the case of mutants deficient in Ferrioxamine E uptake.
