Cell-wall components (cellulose, hemicellulose (oat spelt xylan), lignin (Organosolv)), and model compounds (levoglucosan (an intermediate product of cellulose decomposition) and chlorogenic acid (structurally similar to lignin polymer units)) have been investigated to probe in detail the influence of potassium on their pyrolysis behaviours as well as their uncatalysed decomposition reaction. Cellulose and lignin were pretreated to remove salts and metals by hydrochloric acid, and this dematerialized sample was impregnated with 1% of potassium as potassium acetate. Levoglucosan, xylan and chlorogenic acid were mixed with CH3COOK to introduce 1% K. Characterisation was performed using thermogravimetric analysis (TGA) and differential thermal analysis (DTA). In addition to the TGA pyrolysis, pyrolysis-gas chromatography-mass spectrometry (PY-GC-MS) analysis was introduced to examine reaction products. Potassium-catalysed pyrolysis has a huge influence on the char formation stage and increases the char yields considerably (from 7.7% for raw cellulose to 27.7% for potassium impregnated cellulose; from 5.7% for raw levoglucosan to 20.8% for levoglucosan with CH3COOK added). Major changes in the pyrolytic decomposition pathways were observed for cellulose, levoglucosan and chlorogenic acid. The results for cellulose and levoglucosan are consistent with a base catalysed route in the presence of the potassium salt which promotes complete decomposition of glucosidic units by a heterolytic mechanism and favours its direct depolymerization and fragmentation to low molecular weight components (e.g. acetic acid, formic acid, glyoxal, hydroxyacetaldehyde and acetol). Base catalysed polymerization reactions increase the char yield. Potassium-catalysed lignin pyrolysis is very significant: the temperature of maximum conversion in pyrolysis shifts to lower temperature by 70 K and catalysed polymerization reactions increase the char yield from 37% to 51%. A similar trend is observed for the model compound, chlorogenic acid. The addition of potassium does not produce a dramatic change in the tar product distribution, although its addition to chlorogenic acid promoted the generation of cyclohexane and phenol derivatives. Postulated thermal decomposition schemes for chlorogenic acid are presented.

In this work, activated carbon (AC) materials, prepared from polyethylene terephthalate (PET) waste bottles were used as the sensing platform for the indirect detection of carbofuran. The morphology and surface properties of the PET-derived AC (PET-AC) were characterized by N2 adsorption/desorption isotherm, X-ray diffraction (XRD), field-emission scanning/transmission electron microscopy (FE-SEM/TEM) and Raman spectroscopy. The electrochemical activity of the PET-AC modified glassy carbon electrode (GCE) (PET-AC/GCE) was measured by cyclic voltammetry and amperometry. The enhanced surface area and desirable porosities of PET-AC are attributed for the superior electrocatalytic activity on the detection of carbofuran phenol, where, the proposed sensor shows low detection limit (0.03 muM) and remarkable sensitivity (0.11 muA muM?1 cm?2). The PET-AC/GCE holds high selectivity towards potentially interfering species. It also provides desirable stability, repeatability and reproducibility on detection of carbofuran phenol. Furthermore, the proposed sensor is utilized for the detection of carbofuran phenol in real sample applications. The above mentioned unique properties and desirable electrochemical performances suggest that the PET-derived AC is the most suitable carbonaceous materials for cost-effective and non-enzymatic electrochemical sensor.

A novel carbofuran-degrading strain CFD-1 was isolated and preliminarily identified as Sphingbium sp. This strain was able to utilize carbofuran as the sole carbon source for growth. The carbofuran hydrolase gene cehA was cloned from strain CFD-1 and expressed in Escherichia coli. CehA could hydrolyze carbamate pesticides including carbofuran and carbaryl efficiently, while it showed poor hydrolysis ability against isoprocarb, propoxur, oxamyl and aldicarb. CehA displayed maximal enzymatic activity at 40 C and pH 7.0. The apparent Km and Kcat values of CehA for carbofuran were 133.22 ± 5.70 muM and 9.48 ± 0.89 s-1, respectively. The site-directed mutation experiment showed that His313, His315, His453 and His495 played important roles in the hydrolysis of carbofuran by CehA. Furthermore, the sequence of cehA is highly conserved among different carbofuran-degrading strains, and there are mobile elements around cehA, indicating that it may be transferred horizontally between different strains.

A biomimetic sensor based on a carbon paste electrode modified with hemin complex and graphene oxide was developed as an alternative technique for the sensitive and selective analysis of carbofuran pesticide. The electrochemical analysis of carbofuran was initially carried out with the biomimetic sensor using cyclic voltammetry within the potential range of -0.2 to 0.8 V vs. Ag/AgCl (KClsat). The sensor showed in square wave voltammetry (SWV) a linear response between 5.0 × 10-6 and 9.5 × 10-5 mol L-1, a sensitivity of 1.1 × 105 (±1.4 × 103) muA L mol-1 and detection limit of 9.0 × 10-9 mol L-1. The sensitive and selective detection of carbofuran was confirmed through the analysis of other pesticides using SWV. When the proposed sensor was applied in food samples, the results obtained in the recovery studies were found to be close to 100%. These results obtained were similar to those of the high performance liquid chromatography (HPLC) method. Furthermore, an electrochemical study was conducted aiming at verifying the importance of the use of hemin complex and graphene oxide in the construction of the sensor. The results obtained showed a clear improvement in selectivity, reproducibility and sensitivity of the proposed sensor.

A set of new aryloxy-quinones were synthesized and evaluated in vitro against the epimastigote form of Trypanosoma cruzi and their unspecific cytotoxicity was tested on murine macrophages J-774 cells. Most of these novel compounds were found to be much more potent and selective than the standard drug nifurtimox. Interestingly, 2-phenoxy-naphthoquinone 3b displayed a remarkable nanomolar inhibitory activity, IC50 = 20 nM, and a high selectivity index, SI = 625. The Epc1 was determined for the most interesting compounds and no correlation with the trypanosomicidal effect was found. Therefore, an in silico study was carried out to obtain a pharmacophoric model and quantitative structure-trypanosomicidal activity relationship. The designed pharmacophore recognized the more potent and selective molecules, exhibiting five pharmacophoric features. A correlation coefficient R2 of 0.99 of pIC50 plotted against the predicted values indicated that the 3D-QSAR equation could be applied to further predictions of newly designed trypanosomicidal compounds.

A luxAB-mutant of the carbofuran degrading bacterium Burkholderia cepacia PCL3 was successfully constructed with the capability to emit a luminescence signal of 1.6×10-3RLUcfu-1. The mutant has a growth pattern and carbofuran degradation ability similar to PCL3 wild-type. The luminescent emission by PCL3:luxAB1 directly correlated with the metabolic activity of the cells. The optimal pH, temperature and n-decanal concentration for luminescence emission are 7.0, 35C and 0.01%, respectively. PCL3:luxAB1 was used to assess the toxicity of carbofuran and carbofuran phenol in basal salt medium (BSM) in which the different sensitivity of the cells is dependent on the biomass concentration. With the luciferase system, the degradative fraction of the augmented PCL3:luxAB1 and the difference between the active augmented PCL3:luxAB1 and indigenous microorganisms at the contaminated site could be indicated.
