A nitrate-dependent Fe(II)-oxidizing bacterium was isolated and used to evaluate whether Fe(II) chemical form or oxidation rate had an effect on the mineralogy of biogenic Fe(III) (hydr)oxides resulting from nitrate-dependent Fe(II) oxidation. The isolate (designated FW33AN) had 99% 16S rRNA sequence similarity to Klebsiella oxytoca. FW33AN produced Fe(III) (hydr)oxides by oxidation of soluble ...
The asymmetric unit of title compound, [Ce(NO(3))(3)(C(15)H(15)NO(2))(2)(CH(3)OH)], consists of two Schiff base 2-meth-oxy-6-[(4-methyl-phen-yl)iminiometh-yl]phenolate (HL) ligands, three nitrate anions and a methanol ligand. The Ce(III) ion is 11-coordinated: three nitrate radical anions coordinate to the Ce(III) ion through O atoms, two HL ligands chelate the Ce(III) ion through the O atoms o...
A major challenge for the bioremediation of toxic metals is the co-occurrence of nitrate, as it can inhibit metal transformation. Geobacter metallireducens, Desulfovibrio desulfuricans, and Sulfurospirillum barnesii are three soil bacteria that can reduce chromate [Cr(VI)] and nitrate, and may be beneficial for developing bioremediation strategies. All three organisms respire through dissimilat...
The asymmetric unit of the title compound, {[Ce(C(3)H(2)O(4))Cl(H(2)O)(3)]·0.5H(2)O}(n), contains a Ce(3+) atom coordinated by a chloride anion, three water mol-ecules and a malonate ligand, and one water mol-ecule of crystallization with a factor of occupancy of 50%. The malonate ligand is bonded to three different symmetry-related metal atoms yielding a one-dimensional coordination polymer ru...
A simple and sensitive fluorimetric method for determination of antiviral drugs: ribavirin, acyclovir, and amantadine hydrochloride has been developed. The method was based on the oxidation of these drugs by cerium(IV) in presence of perchloric acid and subsequent monitoring the fluorescence of the induced cerium(III) at lambdaexcitation 255 and lambdaemission 355 nm. Different variables affect...
