Complexation of uranium(VI) with the siderophore desferrioxamine B
Siderophores are microbial produced low molecular weight iron chelators and strongly bind to hard Lewis acids. The siderophore desferrioxamine B (DFO) has hydroxamate functional groups, similar to acetohydroxamic acid (AHA), a ligand that is proposed for actinide complexation in advanced separations. In the proposed separation involving AHA, the exact role of the complex in the extraction behav...
متن کاملBiosorption of Uranium (VI) from Aqueous Solution by Pretreated Aspergillus niger Using Sodium Hydroxide
The removal of uranium and any other heavy metals from wastewater might be achieved via several chemical or physical treatment techniques. Biosorption process has been considered as a potential alternative way to remove contaminants from industrial effluents. Moreover the surface of biosorbent was characterized by SEM. The biosorption characteristics of uranium (VI) on pretreated A...
متن کاملQuantitative structure-activity relationships for aqueous metal-siderophore complexes.
Siderophores, biogenic chelating agents that facilitate the solubilization and uptake of ferric iron, form stable complexes with a wide range of nutrient and contaminant metals and thus may profoundly affect their fate, transport, and biogeochemical cycling. To understand more comprehensively the factors that control the stability and reactivity, as well as the potential for microbial uptake, o...
متن کاملFusarinine C, a novel siderophore-based bifunctional chelator for radiolabeling with Gallium-68.
Fusarinine C (FSC), a siderophore-based chelator coupled with the model peptide c(RGDfK) (FSC(succ-RGD)3), revealed excellent targeting properties in vivo using positron emission tomography (PET). Here, we report the details of radiolabeling conditions and specific activity as well as selectivity for (68)Ga. (68)Ga labeling of FSC(succ-RGD)3 was optimized regarding peptide concentration, pH, te...
متن کاملsiderophore from Mycobacterium smegmatis
The extracellular siderophore from Mycobacterium smegmatis, exochelin MS, was isolated from iron-deficiently grown cultures and purified to > 98 % by a combination of ion-exchange chromatography and h.p.l.c. The material is unextractable into organic solvents, is basic (pI = 9.3-9.5), has a Amax. at 420 nm and a probable K. for Fe3+ of between 1025 and 1030. Its structure has been determined by...
