Glycerol, as a nontoxic, biodegradable and sustainable solvent, together with biomass-derived ethanol was employed in this work to fractionate and purify enzymatic hydrolysis lignin (EHL) from enzymatic hydrolysis residue (EHR). Detailed characterizations, including GPC, FTIR, 13C and 2D-HSQC NMR and Py-GC/MS analysis were conducted to provide a broad evaluation of the obtained lignin fractions. The GPC analysis revealed that the proposed method could realize the efficient fractionation of EHL with relatively narrow polydispersity, and three lignin fractions (F1, F2 and F3) with gradually increased molecular weight (M¯n from 8690 to 20110 g mol?1) and reduced polydispersity were obtained. The structural characterization (FTIR, NMR and Py-GC/MS) indicated that with the increase of molecular weight, G unit content in lignin fractions increased due to the more stable C[sbnd]C bond formed by C5 in G unit. Besides, F1 contained highest phenolic acids, which indicated the potential application of F1 in bioactive products. The study of glycerol recycle showed that glycerol could be recycled with high recovery rate and re-employed to fractionate lignin efficiently. Consequently, the study indicated that compared with traditional dissolving by multiple organic solvents, the sequential dissolution in glycerol-ethanol solvent was a novel, green, and efficient way to fractionate EHL and reduce its molecular weight and structural heterogeneity.

This paper describes a fluorescence detection method for N- methylcarbamate (NMC) pesticides in micellar electrokinetic chromatography (MEKC) separation. Fulfillment of the fluorescence detection hinged on the discovery that quaternary ammonium surfactants (particularly cetyltrimethylammonium bromide, CTAB), besides serving as hydrophobic pseudophases in MEKC, are also capable of catalyzing the thermal decomposition of NMCs to liberate methylamine. Thus, a multifunctional MEKC medium consisting of borate buffer, CTAB, and derivatizing components (o- phthaldialdehyde/2-mercaptoethanol) was formulated, which allowed first normal MEKC separation, subsequent thermal decomposition, and finally in situ derivatization of NMCs. With careful optimization of the operation conditions, fluorescence detection of 10 NMC compounds was achieved, with column efficiencies typically higher than 50 000 and detection limits better than 0.5 ppm. The present work represents an unprecedented effort in capillary electrophoresis (CE), in which an intact capillary was consecutively utilized as chambers for separation, decomposition, derivatization, and detection, without involving any interfacing features. The success in the implementation of such a detection system resulted in strikingly simple instrumentation as compared with the traditional postcolumn fluorescence determination of NMCs by reversed-phase HPLC. Similar protocols should be workable in the determination of a wide range of pesticides and pharmaceuticals in CE formats.

Agriculture; Biotechnology; Microbiology; Agricultural soil science; Pesticide; Environmental pollution; Bacteria biodegradation immobilized cells carbamates; Psychrophile Carbamates are synthetic pesticides, extensively used throughout the world due to their broad specificity against various insect pests. However, their enormous and inadequate use have made them a potential threat to the environment. At low temperature, degradation of carbamates becomes difficult mainly because of low biological activity. In the present study, we isolated a bacterial strain from a low temperature climate where the N-methylated carbamates are used for crop protection. The bacterium, was identified as Pseudomonas plecoglossicida strain (TA3) by 16S rRNA analysis. Degradation experiments with both free and immobilized cells in minimal salt medium indicated that the strain TA3 utilized carbaryl, carbofuran and aldicarb as both carbon and nitrogen source. TA3 can grow well at 4 C and demonstrated the ability to degrade three carbamates (50 mugml?1) at low temperature. The immobilized cells were found more efficient than their free cells counter parts. Immobilized cells has ability to degrade 100% of carbamates at 30 C while 80% at 4 C but incase of their free cells counter parts the efficiency to degrade carbamates was less which was 60% at 4 C and 80% at 30 C. TA3 free cellsextract also depicted high activity against all the three carbamates even at 4 C indicating a possible enzymatic mechanism of degradation.

The most relevant parameters of a multimode inlet were optimized to increase the injection volume up to 25 muL using solvent vent mode in order to improve the sensitivity of the gas chromatography-mass spectrometry system. Consequently, the implementation of a concurrent backflushing was necessary to largely prevent the expected loss of performance derived from such matrix load out of a general-purpose extraction (EN-15622-QuEChERS). Additionally, four mixtures of compounds used as analyte protectants were tested using spiked physalis to enhance the quality of signals. The chosen mixture remarkably improved sensitivity and yield better peak shapes, significantly more than others also tested. The analysis of pesticide residues in exotic fruits using instruments of limited selectivity is challenging since these complex matrices usually give notably dirty extracts. This scheme included an instrumental optimization and the addition of selected compounds that enabled to selectively reach limits of quantitation of 0.01 mg kg-1 for most analytes.

Electric Literature of 1563-38-8, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 1563-38-8, 2,2-Dimethyl-2,3-dihydrobenzofuran-7-ol, introducing its new discovery.

The haptens 4-[[(2,3-dihydro-2,2-dimethyl-7-benzofuranyloxy)carbonyl]- amino]butanoic acid (BFNB) and 6-[((2,3-dihydro-2,2-dimethyl-7-benzofuranyloxy)- carbonylamino]hexanoic acid (BFNH) were synthesized and then used to develop a rapid, specific and sensitive ELISA method to determine residues of the pesticide carbofuran in a variety of matrices. A hybridoma cell line (5D3) producing anti-carbofuran monoclonal antibodies (MAbs) was also established. Based on the MAbs in combination with the heterologous hapten BFNH coupled to either horseradish peroxidase (HRP) or ovalbumin (OVA), four ELISAs (formats I-IV) for the quantification of carbofuran were developed and compared. Among them, the optimized format II (the conjugate-coated direct competitive ELISA) showed the best characteristics, with an IC50 value of 18.49 ng/mL, a limit of detection of 0.11 ng/mL and the shortest assay time (1 h). This ELISA method was then applied to the determinations of carbofuran in environmental water, soil and food samples. The relative standard deviations (R.S.D.s) ranged from 1.8% to 21.3% and the mean recoveries were 104.6%, 108.3%, 106.3% and 100.1% for water, soil, lettuce and cabbage, respectively. Thus, the ELISA method of format II exhibited the potential to develop commercial ELISA kits for a rapid detection of carbofuran for human health and environmental safety.

Carbofuran is a toxic carbamate pesticide, and its use has increased in recent years. While marketing information indicates stability in different chemical media, carbofuran exhibits relative photolability. The aim of this research was to decompose carbofuran and to identify the photoproducts achieved when two different doped titania photocatalysts were employed under UV irradiation. The iron-doped TiO2 materials were obtained (a) via a hydrothermal method and (b) by an ultrasound-assisted sol?gel method. The precursors were TiOSO4?xH2O and Fe3(NO3)·9H2O. X-ray studies confirmed that the anatase phase of the iron-doped TiO2 resulted from the two preparation methods. The photocatalytic performance of the prepared materials was monitored by LC/ESI-QTOF-MS, enabling the identification of photoproducts: oxo-carbamates, hydroxylated benzofuranes, a carboxamide, and one amine. By using the iron-doped TiO2 materials, 2,2-dimethyl-2,3-dihydrobenzofuran-3,7-diol was the most abundant photoproduct, and N,2,2-trimethyl-2,3-dihydrobenzofuran-7-amine was the only compound that had not been previously reported in the photolysis and photocatalysis of carbofuran. The product 3-hydroxy carbofuran, a cholinesterase inhibitor, was quantified and was found to be transformed into compounds that lack this inhibitive property.

Carbofuran can be hydrolysed to from 2,3-dihydro-2,2-dimethyl-7-benzofuranol (BF). BF is coupled with 4-aminoantipyrene (AP) in presence of potassium ferricyanide (K3Fe(CN)6) to generate red coloured derivative(BFAP)having lambdamax 530 nm. Cloud point extraction (CPE) methodology and using surfactant Triton X-100 as extractant was applied as a preconcentration step prior to HPLC, the surfactant-rich phase containing BFAP was then analysed by HPLC in visible region. The high back ground absorbance of Triton X-100 in UV region was completely avoided. A new visible detection method with high-performance liquid chromatography (HPLC) has been developed for the determination of carbofuran. Using this method, we found that carbofuran residues could be determined with recoveries ranging from 80.4% to 84.5%, relative standard deviations in the range of 2.51-3.26% for three fortified rice levels, and the limit of detection as 5.0 × 10-4 cJ/cK.

Although the relationship between chemical intake and resulting concentration in hair remains incompletely elucidated, the transfer from blood to hair bulb living cells is generally considered the main route of incorporation. The present work investigated the correlation between blood and hair concentration of 23 pesticides/metabolites from different chemical classes in rats submitted to chronic controlled exposure. Long-Evans rats were administered pesticides by gavage three times per week over a 90-day period. After hair sample decontamination, pulverization, and extraction, compounds were analyzed by gas chromatography tandem mass spectrometry (GC-MS/MS). Blood was collected at sacrifice, immediately turned into plasma, and analyzed after extraction for the same compounds by GC-MS/MS. The data obtained for all the investigated compounds demonstrated significant association between plasma and hair concentrations (P value of 2.97E?45 and RPearson of 0.875), with the exception of three outliers. For all the target compounds, water solubility, lipophilicity, molecular weight, and charge were therefore investigated in order to understand the role of these parameters in outliers? specific behavior. Although a possible change in the charge through the transfer from blood to hair might be suspected for two outliers, on the whole the physicochemical parameters investigated here did not seem to influence incorporation of chemicals into hair. Our results support that the concentration of chemicals in hair mainly depends on the respective concentration in plasma and suggest that for most compounds, the transfer from blood to hair would not represent a limiting step in the incorporation.
