New potentiometric sensor for copper determination in waste waters based on a new type of modified GC electrode
(Analytical and Bioanalytical Chemistry, 2012)
The potentiometrical analysis of Cu2+ using Nafion- modified electrode with Cu complex with DPABA (Methyl 3,5-bis{bis-[(pyridin-2-yl)methyl]amino}methyl)benzoate) incorporated, is described. Parameters and conditions such ...
In vivo self-hydroxylation of an iron-substituted manganese-dependent extradiol cleaving catechol dioxygenase
(Springer, New York, 2011)
The homoprotocatechuate 2,3-dioxygenase from Arthrobacter globiformis (MndD) catalyzes the oxidative ring cleavage reaction of its catechol substrate in an extradiol fashion. Although this reactivity is more typically ...
Yeast surface display for the expression, purification and characterization of wild-type and B11 mutant glucose oxidases
(Academic Press Inc Elsevier Science, San Diego, 2013)
Glucose oxidase (GOx) catalyzes the oxidation of glucose to form gluconic acid and hydrogen peroxide, a reaction with important applications in food preservation, the manufacture of cosmetics and pharmaceuticals, and the ...
Characterization of temperature-sensitive and lipopolysaccharide overproducing transposon mutants of Pseudomonas putida CA-3 affected in PHA accumulation
(Wiley-Blackwell Publishing, Inc, Malden, 2009)
A library of 20 000 transposon (Tn5) mutants of the gram-negative bacterium Pseudomonas putida CA-3 was generated and screened for adverse affects in polyhydroxyalkanoates (PHA) accumulation. Two mutants of interest were ...
Importance of N-terminal proline for the promiscuous activity of 4-oxalocrotonate tautomerase (4-OT)
(Serbian Chemical Soc, Belgrade, 2016)
Michael addition of aldehydes to nitro-olefins is an effective method to obtain useful chiral gamma-nitroaldehydes. gamma-Nitroaldehydes are precursors for chiral gamma-aminobutyric acid analogues, which have numerous ...
Hydrophilic Interaction Planar Chromatography of Geometrical Isomers of Selected Co(Iii) Complexes
(Taylor & Francis Inc, Philadelphia, 2012)
The retention behavior of fourteen geometrically isomeric Co(III) complexes: three pairs of neutral facial-meridional (fac-mer) isomers, one pair of cis-trans isomeric complexes of neutral type, and three pairs of cationic ...
Synthesis of thiophosphoramidates in water: Click chemistry for phosphates
(Royal Soc Chemistry, Cambridge, 2011)
An aqueous method for the preparation of N,S-dialkyl thiophosphoramidates is reported. Thiophosphorylation of alkylamines was performed using SPCl3 in aqueous reaction media, and the resulting thiophosphoramidate-S-anions ...
Geometries of stacking interactions between phenanthroline ligands in crystal structures of square-planar metal complexes
(Springer, New York, 2011)
Stacking interactions of phenanthroline square-planar complexes in crystal structures were studied by analyzing data from the Cambridge Structural Database. In most of the crystal structures, two phenanthroline complexes ...
Influence of Pressure and Time on Extraction Process Using Supercritical Co2
(Technical Faculty, Bor-Serbia, Bor, 2008)
The supercritical fluid extraction (SFE) by carbon dioxide (CO2) of Salvia officinalis L. was investigated. SFE by CO2 was performed at different pressure (80, 100, 150, 200 and 300 bar) and constant temperature of 40 ...
Use of cyclic voltammetry to determine the antioxidant capacity of berry fruits: Correlation with spectrophotometric assays
(INT SOC HORTICULTURAL SCIENCE-ISHS, 2019)
Background of the study – Among fruits, berry fruits contain a very large complex of chemical compounds that are responsible for their antioxidant properties. As far as we know there is no data available from cyclic ...
