Cell wall invertase immobilisation within gelatin gel
(Elsevier Sci Ltd, Oxford, 2011)
Yeast cell wall invertase (CWI) was immobilised within 10% gelatin hydrogel. The result of entrapment was the complete immobilisation of all the added CWI. The activity of immobilised biocatalyst was 93 +/- 3 U/g, with ...
Biodegradation of the aromatic fraction from petroleum diesel fuel by Oerskovia sp. followed by comprehensive GC x GC-TOF MS
(Elsevier, 2019)
Polycyclic aromatic hydrocarbons (PAHs) from petroleum and fossil fuels are one of the most dominant pollutants in the environment. Since aromatic fraction from petroleum diesel fuel is mainly composed of PAHs, it is ...
Mixed RuO2/TiO2 uniform microspheres synthesized by low-temperature ultrasonic spray pyrolysis and their advanced electrochemical performances
(Elsevier, 2019)
Uniformly-shaped, spherical RuO2/TiO2 particles were synthesized exclusively by one-step ultrasonic spray pyrolysis USP) of a mixture of n-butylorthotitanate and ruthenium chloride acidic aqueous solutions. The USP temperature ...
Production of levan by Bacillus licheniformis NS032 in sugar beet molasses-based medium
(Elsevier, 2019)
The production of levan by Bacillus licheniformis NS032 in a medium based on sugar beet molasses was studied. High polysaccharide yields were produced by using diluted molasses (100-140 g/L of total sugars) with the addition ...
Iron complexes of dietary flavonoids: Combined spectroscopic and mechanistic study of their free radical scavenging activity
(Elsevier Sci Ltd, Oxford, 2011)
Combined spectroscopic (UV/visible, Raman, MS) and theoretical approaches were used to assess interaction of iron(III) with quercetin and baicalein in aqueous buffered solutions. Obtained results implicated formation of ...
Removal of alprazolam from aqueous solutions by heterogeneous photocatalysis: Influencing factors, intermediates, and products
(Elsevier Science Sa, Lausanne, 2017)
Efficiency of heterogeneous photocatalytic degradation of aiprazolam was investigated. The structural and morphological properties of ZnO were investigated in detail. It was found that ZnO has wurtzite structure with ...
Behaviour of non-standard composition copper bearing anodes from the copper refining process
(Elsevier, 2010)
This paper addresses on investigation the possibility of electrolytic treatment the sulphur acidic waste solution, obtained in the conventional electrolytic copper refining process. Beside the high copper concentration, ...
Efficient removal of priority, hazardous priority and emerging pollutants with Prunus armeniaca functionalized biochar from aqueous wastes: Experimental optimization and modeling
(Elsevier, 2018)
This paper investigates the ability of the phosphoric acid functionalized Prunus armeniaca stones biochar (AsPhA) prepared by thermochemical activation to remove lead (Pb2+), cadmium (Cd2+), nickel (Ni2+), naproxen and ...
From titania to titanates: Phase and morphological transition in less alkaline medium under mild conditions
(Elsevier, 2019)
In this work, nine products were prepared by modifying the experimental conditions (6, 12 and 18 h at 110, 135 and 160 °C) of hydrothermal treatment of starting nanoanatase in significantly less concentrated alkaline medium ...
Characterisation of leucyl aminopeptidase from Solanum tuberosum tuber
(Elsevier Sci Ltd, Oxford, 2010)
Potato juice (a waste product from the starch industry) is a potential source of novel enzymes for food applications. For use in the production and improvement of food protein hydrolysates, commercially available exopeptidases, ...
