Interactions of trivalent and tetravalent heavy metal-siderophore complexes with ${it Pseudomonas fluorescens}$

Yoshida, Takahiro; Ozaki, Takuo; Onuki, Toshihiko; Francis, A. J.*

Accumulation of Fe(III)-, Eu(III)-, Hf(IV)-, and Pu(IV)-desferrioxamine B (DFO) complexes by aerobic bacterium, ${it Pseudomonas fluorescens}$ (ATCC 55241) was studied in order to elucidate stability of DFO complexes on biosorption. When Eu(III)-DFO complex was incubated with bacteria in 0.1 M Tris-HCl buffer (pH = 7.2), the metals were removed from solution, with no change in DFO concentration in solution. On the other hand, Fe(III)-, Hf(IV)-, and Pu(IV)-DFO complexes were not accumulated to bacteria. Metals with high charge to ionic radius ratio (Z/r) suppress the dissociation of complexes, leading small bacterial accumulation.
