Chemical Characterization of Siderophores
Siderophores are divided to 2 main structural groups: hydroxamates and catecholates (Drechsel et al. 1995). Hydroxamate siderophores are produced both by bacteria and fungi, while catecholates are reported to the produced only by bacteria (Messenger and Ratledge, 1985). A third group of siderophores the carboxylate (= complexone) type has been reported to be produced exclusively by fungi belong...
متن کاملChemical characterization of urinary glycopeptides.
We prepared human urinary glycopeptides from the supernatant liquid remaining after precipitation of the nondialyzable fraction with cetylpyridinium chloride. Using cation exchange and affinity chromatographies and gel filtration, we obtained 28 glycopeptide subfractions. By compositional analyses of sugar and amino acid, and by reducing-terminal analyses after reduction with NaBH4, we determin...
متن کاملChemical characterization of asturian cider.
Ninety-four samples of Asturian natural cider were analyzed for titratable and volatile acidities, pH, alcoholic, total polyphenol, and acidic polysaccharide contents, nonvolatile acids, polyalcohols, residual sugars, and major volatile compounds. A partial least-squares regression analysis (PLR-1) was performed to correlate the chemical composition and the origin of the raw material, the cider...
متن کاملWet chemical synthesis and physical characterization of doped CeO2 nanoparticles
Solid electrolytes based on doped cerium oxide, Ce(M)O2-δ (M = rare-earth cations), are of considerable interest for potential use in low temperature solid oxide fuel cells (LTSOFCs) due to its higher ionic conductivity than YSZ based solid electrolyte. In this research work, crystalline, pure Ce1-xMxO2-δ (where M = Gd or Sm, x = 0.10 or 0.20) based nanoparticles were prepared by chemical prec...
