Characterization and reactivity of biogenic manganese oxides for ciprofloxacin oxidation.
Biogenic manganese oxides (BioMnOx) were synthesized by the oxidation of Mn(II) with Mn-oxidizing bacteria Pseudomonas sp. G7 under different initial pH values and Mn(II) dosages, and were characterized by X-ray diffraction, X-ray photoelectron spectroscopy, and UV-Vis absorption spectroscopy. The crystal structure and Mn oxidation states of BioMnOx depended on the initial pH and Mn(II) dosages...
متن کاملA Study of Cerium–Manganese Mixed Oxides for Oxidation Catalysis
Cerium–manganese mixed oxides with compositions of Ce0.5Mn0.5O1.75 and Ce0.8Mn0.2O1.9 were prepared by the citric-acid (Pechini) method and their catalytic properties were compared to CeO2 and Mn2O3. The mixed oxides exhibited higher specific rates than either CeO2 or Mn2O3 for oxidation of both methane and nbutane. While XRD measurements of the mixed oxides suggested that the materials had pri...
متن کاملOxidation of Phenol in Acidic Aqueous Suspensions of Manganese Oxides
-Phenol (benzenol) oxidation by three synthetic manganese oxides (buserite, manganite, and feitknechtite) has been studied in aerated, aqueous, acidified suspensions. The rate of reaction was pH dependent. Oxidation was greatly enhanced below pH 4, when diphenoquinone and p-benzoquinone were identified as the first products. Initial reaction rate was correlated with standard reduction potential...
متن کاملMicrobial Manganese ( Iii ) Reduction Fueled by Anaerobic Acetate Oxidation
Background: Microbial manganese (Mn) cycling in marine and freshwater environments is generally assumed to consist of Mn oxidation in oxic water columns and Mn(IV) oxide reduction in anoxic sediments [1] as the only two bioavailable Mn redox species. This dogma was recently overturned with the discovery that soluble Mn dominates the soluble Mn pool at μM concentrations in suboxic environments [...
متن کاملMicrobial manganese(III) reduction fuelled by anaerobic acetate oxidation.
Soluble manganese in the intermediate +III oxidation state (Mn3+ ) is a newly identified oxidant in anoxic environments, whereas acetate is a naturally abundant substrate that fuels microbial activity. Microbial populations coupling anaerobic acetate oxidation to Mn3+ reduction, however, have yet to be identified. We isolated a Shewanella strain capable of oxidizing acetate anaerobically with M...
