The kinetics of thermal unfolding of apo- and holo-Chromobacterium violaceum phenylalanine hydroxylase (cPAH) was investigated using circular dichroism (CD) over the temperature range 44-76 degrees C. In addition to the native cofactor (FeII), the unfolding kinetics of holo-cPAH was characterized using ZnII and CoII as cofactors. Kinetic profiles for apo- and holo-cPAH showed a single-phase exponential rise in the CD signal at lambda=222 nm and a first-order dependence on protein concentration. The ...

The hydrodesulfurization (HDS) of dibenzothiophene (DBT) on a series of Pd–Pt/γ-Al2O3 catalysts was studied as a function of the Pd/(Pd + Pt) molar ratio at different reaction conditions. It was determined that the catalytic performance in HDS is controlled by the Pd/(Pd + Pt) molar ratio. In particular, a synergetic effect exists rather in the development of the hydrogenation (HYD) route of HDS of dibenzothiophene than in the activity, but both can be controlled from the Pd/(Pd + Pt) molar ratio. An analysis ...

The photocatalytic oxidation of the azo dye Orange-II (Or-II) using Fe loaded TiO2 (Fe–TiO2) was studied under ultraviolet (UV), visible (vis) and simultaneous UV–vis irradiations using a solar light simulator. Photocatalysts were characterized by means of XRD, SEM-EDX, FTIR and DRS. Fe3+ species, identified in XPS analyses, were responsible of the increased absorption of visible light. Moreover, DRS analyses showed a decrease in the bandgap due to Fe3+ loading. Photocatalystic tests proved that Fe ...

Phenylalanine hydroxylase (PAH) is a non-heme iron dioxygenase catalyzing the conversion of phenylalanine to tyrosine and is present in both prokaryotic and eukaryotic organisms. A relatively simple PAH is expressed by Chromobacterium violaceum, a gram-negative bacterium found in tropical and subtropical regions. The effects of temperature, pH and metals on the stability and catalytic activity of Chromobacterium violaceum PAH were determined by steady-state kinetics, circular dichroism (CD) and differential ...

Los estudios de dinámica de población de los enemigos naturales de las plagas han demostrado que cambios en la densidad de la presa o del huésped inciden en la efectividad biocontroladora de los insectos depredadores o parasitoides. En el presente estudio se evaluó el efecto de la densidad de población de la mosca blanca de los invernaderos, Trialeurodes vaporariorum, sobre la eficiencia de búsqueda del depredador Delphastus pusillus, mediante la determinación de la respuesta funcional. A partir ...

In this work, TiO2 photocatalysts were synthesized using a conventional sol-gel and hydrothermal synthesis methods with steam pressure treatment. Photocatalysts were characterized by X-ray diffraction (XRD), diffuse reflectance spectra (DRS) and N2 adsorption-desorption. The photoactivity of the samples was analyzed towards the photooxidation of the azo dye Orange II (Or-II) and phenol using different illumination set-ups to compare the activity features of photocatalysts. The effect of the synthesis ...
