Abstract:

Monocyclic phenolic compounds (MCPCs) from petroleum and coal sources mainly include phenol, cresols, and xylenols. A newly isolated 2,3-xylenol-degrading strain,Pseudomonassp. XQ23, was found to be capable of degrading up to 10 MCPCs for the first time. Addition of easy-to-degrade MCPCs such as phenol and cresols helped decompose hard-to-degrade xylenols and the sequential digestion of the phenolic substrates was highly dependent on their molecule structures. The action on multiple MCPCs by the new isolate XQ23 from this work revealed useful clues on the co-biodegradation of multiple pollutants.

Abstract:

Xylenol is a phenolic chemical substance having two methyl groups and one hydroxyl group attached to a benzene ring and has six isomers. 2,4-xylenol is the only isomer of the xylenol molecule that is in the liquid phase while the remaining isomers are all in crystal form at room temperature. In the scope of this study, we have experimentally investigated ionization and dissociation properties of xylenol isomers. All experiments were carried out by using a time of flight mass spectrometry (TOF-MS) system coupled with a femtosecond laser system. The laser pulse power-dependent multiphoton ionization of xylenol isomers was investigated by using IR (800 nm) femtosecond laser pulses having a pulse width of ∼90 fs in duration and laser intensities changing from 2.6 × 1013 to 2.6 × 1014 W/cm2. Theoretically, molecular orbitals (LUMO+1, LUMO, HOMO, HOMO–1), vertical and adiabatic ionization energies were calculated using density functional theory (DFT) with B3LYP functional and 6–311++G(d,p) basis set by following geometry optimization and performing conformational analysis.

Abstract:

5-Hydroxyisophthalic acid is of practical interest in the synthesis of polymers, drugs, cosmetics. The methods for its preparation described in the literature are characterized by a number of significant drawbacks, which hinders the use of this compound in the development of new materials with valuable consumer properties. In this regard, a method for the synthesis of 5-hydroxyisophthalic acid by the oxidation of 3, 5-xylenol has been developed. It has been established that the hydroxyl group inhibits the oxidation of methyl groups; therefore, to carry out oxidative transformations, the hydroxyl group was replaced by acetyl. For this, 3,5-xylenol was acylated with acetic anhydride in the presence of sulfuric acid. The resulting 3, 5-dimethylphenylacetate is oxidized by atmospheric oxygen in an acetic acid medium in the presence of a catalytic system containing cobalt acetals manganese and bromide ions up to 5-acetoxyisophthalic acid. The effect of temperature on the reaction was studied and the activation energy was determined. It was 50 ± 5 kJ/mol that corresponds to the activation energy of oxidation of alkylaromatic hydrocarbons. The dependence of the rate of the process and the yield of the target product on the concentrations of the starting compound and the components of the catalytic system is investigated. It has been established that carrying out the oxidation process of 3,5-dimethylphenylacetate at its initial concentration of 0.75 mol/l, temperature 110 °C and cobalt (II) acetate concentration 0.1 mol/l, sodium bromide 0.05 mol/l, manganese (II) acetate 0.003 mol/l provides the reaction with high rate and the yield of 5-acetoxyisophthalic acid 70-75%. In these conditions, the balance experiment was carried out. 5-Acetoxyisophthalic acid is of practical interest as a monomer for heat-resistant polymers. To obtain 5-hydroxyisophthalic acid, 5-acetoxyisophthalic acid is subjected to alkaline hydrolysis.

Abstract:

Abstract We describe a colorimetric method for assay of microsomal aminopeptidase (EC 3.4.11.2) activity in serum. We use a new substrate, L-leucyl-3-carboxy-4-hydroxyanilide, p-xylenol as coupler, and sodium metaperiodate as oxidizing reagent. The colored substance formed by the oxidative condensation between p-xylenol and 5-aminosalicylic acid absorbs maximally at 635 nm, and can be directly measured in serum. In a previous method for this enzyme, L-leucyl-beta-naphthylamide was used as substrate and beta-naphthylamine, a carcinogenic reagent used as a standard in making the assay, was unsuitable for routine use. We found a close correlation between results obtained with the new, safer method and with the previous method.

Abstract:

Isolation of phenols from the middle oil fraction(170-230°C) of tar produced in the multi-cogeneration system has been investigated for the purpose of recovering valuable pure phenols, such as phenol, cresols, xylenol and ethyl-phenol. Phenolic compounds were separated from the middle oil by liquid-liquid extraction using alkali and sulfuric acid. The yield of phenolic fraction from the middle oil (170-230°C) is up to 37%, which is much higher compared with those of metallurgical coke plants. Chromatography-mass spectrometry was used to analyse phenolic compounds. The result shows that the phenol content is less than 2%, and main compounds are cresol(14%), xylenol(20%) . Phenols of the middle oil fraction(230-280°C) was also analysed, which main contain methyl naphthol(20%).

Abstract:

The electrochemical reduction behaviour of xylenol orange, XO, in aqueous medium was studied over a pH range of 2.3–9.6 at a hanging mercury drop electrode, HMDE, on the basis of cyclic voltammetric, and double-potential step chronoamperometric and chronocoulometric data. The experimental results indicate that in acid medium (pH 2.28) the reduction of XO proceeds via an ECEC, first-order mechanism giving a single two-electron diffusion-controlled cyclic voltammetric wave. It was concluded that the rate-determining step is the protonation of the protonated anion intermediate to the final product, with rate constant k2 of 0.26 s−1. At pH 7.25 the reduction follows an ECE kinetics along two cyclic voltammetric waves in which the first wave was attributed to an EC, first-order process and the second wave to an irreversible electron transfer step, E. On addition of lanthanum(III) to xylenol orange, it forms 1:1 and 1.2 La(III)–XO chelates, which are adsorbed and reduced on the HMDE at more negative potentials than the peak potential of free XO. The adsorptive cathodic stripping voltammetry, ACSV, of these chelates was studied using the square-wave, SW, method. It was found that the SW-ACSV of La(III)–XO can be applied to the determination of lanthanum at the nanomole level. Optimum conditions and the analytical method of determination were presented and discussed. Keywords: electrochemical, reduction mechanism, xylenol orange, lanthanum complex, double potential step chronoamperometry and chronocoulometry, stripping voltammetric determination.

Abstract:

ABSTRACTIn addition to growing onp-cresol,Pseudomonas putidaNCIMB 9866 is the only reported strain capable of aerobically growing on 2,4-xylenol, which is listed as a priority pollutant by the U.S. Environmental Protection Agency. Several enzymes involved in the oxidation of thepara-methyl group, as well as the corresponding genes, have previously been reported. The enzyme catalyzing oxidation of the catabolic intermediate 4-hydroxyisophthalate to the ring cleavage substrate protocatechuate was also purified from strain NCIMB 9866, but its genetic determinant is still unavailable. In this study, the genehipH, encoding 4-hydroxyisophthalate hydroxylase, from strain NCIMB 9866 was cloned by transposon mutagenesis. Purified recombinant HipH-His6was found to be a dimer protein with a molecular mass of approximately 110 kDa. HipH-His6catalyzed the hydroxylation of 4-hydroxyisophthalate to protocatechuate with a specific activity of 1.54 U mg−1and showed apparentKmvalues of 11.40 ± 3.05 μM for 4-hydroxyisophthalate with NADPH and 11.23 ± 2.43 μM with NADH and similarKmvalues for NADPH and NADH (64.31 ± 13.16 and 72.76 ± 12.06 μM, respectively). The identity of protocatechuate generated from 4-hydroxyisophthalate hydroxylation by HipH-His6has also been confirmed by high-performance liquid chromatography and mass spectrometry. Gene transcriptional analysis, gene knockout, and complementation indicated thathipHis essential for 2,4-xylenol catabolism but not forp-cresol catabolism in this strain. This fills a gap in our understanding of the gene that encodes a critical step in 2,4-xylenol catabolism and also provides another example of biochemical and genetic diversity of microbial catabolism of structurally similar compounds.

Abstract:

An novel Lead (II)-dithizone-xylenol orange tenary complex spectrophotometry was developed for the determination of Pb2+ in wastewater. For this purpose, the parameters of spectrophotometry such as the detection wavelength, pH value, the dosage of dithizone-xylenol orange and reaction time were studied and optimized through orthogonal tests. The method was linear in the ranges from 2.1×10-3 to 6.0 μg·mL-1 for Pb2+ with R2≥ 0.999. The procedure allowed efficient recovery of the investigated Pb2+ ranging between 95 % and 103 % with a relative standard deviation (RSD) ≤ 2.1 for actual wastewater samples spiked with 1.00, 2.00 and 3.00 μg·mL-1 of standard Pb2+, respectively. These results show the method can be applied to the direct determination of Pb2+ in wastewater, avoiding the use of toxic extrant (chloroform) and masking reagent (sodium cyanide) in the traditional methods and time-consuming procedures, moreover, the investigated method is simple, accurate, reliable, and inexpensive, which implies the potential of this technique for Pb2+ monitoring in wastewater samples.

Abstract:

Photooxidized psoralen solutions possess a variety of biological effects, which implementation mechanism may presumably involve hydroperoxides. Here, the hydroperoxide content in photooxidized psoralen solutions was assessed using photometric FOX assay (from Ferrous Oxidation + Xylenol Orange). FOX reagent with 10× content of Xylenol Orange, modified for quantitative analysis of up to 50 μM of hydroperoxides in aqueous phase was used in experiments. During photooxidation of 0.1 mM psoralen in phosphate buffer solution, hydroperoxide production increases with dose of UVA irradiation (~2.5 μM eq. of H2O2 for dose of 252 kJ/m2 and ~11 μM eq. of H2O2 for dose of 1512 kJ/m2) and reaches ~16.5 μM eq. of H2O2 at the highest dose investigated (3024 kJ/m2). A comparison of kinetics of psoralen photolysis and hydroperoxide generation allows us to suggest that generation of hydroperoxide results from the secondary photochemical processes involving psoralen photoproducts, presumably from photoinduced autooxidation of aldehydic photoproducts of psoralen.

Abstract:

ABSTRACT The xlnD gene from Pseudomonas alcaligenes NCIMB 9867 (strain P25X) was shown to encode 3-hydroxybenzoate 6-hydroxylase I, the enzyme that catalyzes the NADH-dependent conversion of 3-hydroxybenzoate to gentisate. Active recombinant XlnD was purified as a hexahistidine fusion protein from Escherichia coli, had an estimated molecular mass of 130 kDa, and is probably a trimeric protein with a subunit mass of 43 kDa. This is in contrast to the monomeric nature of the few 3-hydroxybenzoate 6-hydroxylases that have been characterized thus far. Like other 3-hydroxybenzoate 6-hydroxylases, XlnD could utilize either NADH or NADPH as the electron donor. P25X harbors a second 3-hydroxybenzoate 6-hydroxylase II that was strictly inducible by specific aromatic substrates. However, the degradation of 2,5-xylenol and 3,5-xylenol in strain P25X was found to be dependent on the xlnD-encoded 6-hydroxylase I and not the second, strictly inducible 6-hydroxylase II.

Abstract:

We have developed a new fluorescence method for the histochemical localization of alkaline phosphatase activity. Calcium phosphate deposited at the sites of alkaline phosphatase activity in a Gomori-type reaction are identified by calcium binding fluorochromes. The calcium binding fluorochromes calcein, calcein blue, and xylenol orange were investigated, with each fluorochrome being included in the alkaline phosphatase incubating medium and used in a single-step procedure. Alkaline phosphatase activity was studied in freeze-substituted, resin-embedded human liver and jejunal biopsies, and each fluorochrome produced intense fluorescence of different colors at sites of alkaline phosphatase activity. Calcein, calcein blue, and xylenol orange produced green, blue, and red fluorescence, respectively. Sites of enzyme activity were accurately localized without evidence of diffusion, and there was an absence of non-enzyme-catalyzed binding of any of the fluorochromes to tissue. This fluorescence method, which is particularly suited to investigating the localization and distribution of the activity of different enzymes in the same section, was used to investigate the distribution and co-localization of alkaline phosphatase and aminopeptidase M in human liver and jejunum.
